|
||
|
|
<p>Simply point, and press the blue circular camera icon to take a photo.
|
||
|
|
If your device supports focus areas, you can touch the part of the screen you want to focus. Touching an area will also
|
||
|
|
(if your device supports it) control the exposure level (e.g., so clicking on a bright area will adjust the exposure
|
||
|
|
so that it becomes less bright). Double tapping will reset the focus and exposure area.</p>
|
||
|
|
|
||
|
|
<p>To zoom, use the slider next to the take photo button, or do a multi-touch "pinch"
|
||
|
|
gesture, or a double-tap-drag gesture. You can also control via the volume keys on your phone or tablet - by default, pressing them will take a
|
||
|
|
photo, but you can change this to zoom in/out from the <a href="#settings">Settings</a>.</p>
|
||
|
|
|
||
|
|
<p>You can press the gallery icon to view your photos
|
||
|
|
(by default saved in the OpenCamera folder) - it will show the most recent image or video. The gallery button's
|
||
|
|
icon will also show a thumbnail for the most recent image/video.</p>
|
||
|
|
|
||
|
|
<p>The screen display is kept on when Open Camera is running as the foreground app (if
|
||
|
|
you want to switch off the display, do so on your device manually).</p>

<p><b>Shutter button</b> - Click the blue circular icon to take
|
||
|
|
a photo. In some cases, you can also hold (long press) for a continuous burst:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Photo mode must be Standard or Fast Burst</li>
|
||
|
|
<li>Settings/"Camera API" must be set to "Camera2 API".</li>
|

<li>Continuous burst only supported on some devices and resolutions.</li>

<p><img src="take_video.png" alt="Switch to video icon" width="32" height="32"><b>Switch to video mode</b> - Clicking the
|
||
|
|
smaller video icon next to the shutter button will switch to video mode. The shutter button will now show a smaller
|
||
|
|
blue dot in a white circle to indicate video mode. Pressing the shutter button will now start and stop video recording.
|
||
|
|
You can return to photo mode by clicking the

|
||
|
|
<ul>
|
||
|
|
<li>When recording video, the main shutter button will turn red to indicate this. A smaller blue shutter button will show,
|
||
|
|
pressing this will take a photo while recording video. Note that different
|
||
|
|
photo modes are not supported when taking photos while recording video, nor is RAW supported. The photo resolution will not
|
||
|
|
in general match the resolution set in preferences, rather it will be set automatically (usually to match the aspect ratio
|
||
|
|
of the video resolution).

<p><img src="switch_camera.png" alt="Switch Camera icon" width="32" height="32"><b>Switch camera</b> - Switches between front and back camera (if your
|
||
|
|
device has both front and back cameras). If your device has more than one front and/or back camera, then this will switch
|
||
|
|
between the first front and back camera.</p>
|

|
|
|

|
|
<p><img src="baseline_add_a_photo_white_48.png" alt="Switch multi-camera icon" width="32" height="32"><b>Switch multi-camera icon</b> -
|
||
|
|
This icon only shows on devices with more than one front and/or back cameras, and allows you to switch between those
|
||
|
|
cameras. For example, a device might have two back cameras, one standard and one ultra-wide, this icon will switch between
|
||
|
|
the standard and ultra-wide camera.
|
||
|
|
Some devices also support cameras that are made up of multiple lenses. The device will automatically switch cameras as required
|
||
|
|
when zooming in or out, but this menu allows you to choose a specific physical lens (e.g. telephoto) to use (requires Camera2 API).
|
||
|
|
If Settings/On screen GUI/"Multiple cameras icon" is disabled, then this icon will not show; instead the "Switch camera"
|
||
|
|
icon can by used to cycle through all the cameras.
|
||
|
|
Note that some other devices do not allow third party applications to access their multiple cameras at all, in which case Open Camera isn't
|
||
|
|
able to use them.</p>

<p><img src="exposure_unlocked.png" alt="Lock Exposure icon" width="32" height="32"><b>Exposure lock</b> - Click to lock or unlock the exposure.
|
||
|
|
When locked, the icon will change to <img src="exposure_locked.png" alt="Exposure Locked icon" width="32" height="32">. Locking the exposure means
|
||
|
|
the exposure doesn't change based on the brightness of the current scene (though you can still adjust the exposure
|
||
|
|
compensation). Note that this isn't guaranteed to work on all devices (doesn't seem to work on Galaxy S3, Nexus 6).</p>

|
|
|
||
|
|
<p><img src="ic_exposure_white_48dp.png" alt="Exposure Compensation icon" width="32" height="32"><b>Exposure compensation, ISO and Manual White Balance</b> - Clicking this will bring
|
||
|
|
a panel with various controls:</p><ul>
|
||
|
|
<li>
|
||
|
|
<b>ISO (top row)</b> - (Not supported on all devices.) A higher ISO setting means the camera is more sensitive to light, though may
|
||
|
|
also result in more noise. This mimics the film speed on traditional film cameras. Select "AUTO" to switch back to
|
||
|
|
automatic ISO mode.
|
||
|
|
If Camera2 API is used, then selecting a non-auto ISO will bring up sliders allowing direct control over the ISO and exposure
|
||
|
|
time (in place of the exposure compensation slider). You can also select "M" to switch straight to manual mode, keeping to the
|
||
|
|
current ISO value.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<b>Exposure compensation (slider)</b> - A higher value increases the exposure, so that pictures come out brighter in low light; a
|
||
|
|
lower value makes pictures darker. One unit of EV changes the brightness of the captured image by a factor of two. +1 EV
|
||
|
|
doubles the image brightness, while -1 EV halves the image brightness. Set to 0 for the default exposure.
|
||
|
|
See <a href="https://en.wikipedia.org/wiki/Exposure_compensation">Exposure compensation</a>.
|
||
|
|
(Only available if the camera supports control of the exposure.)
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<b>ISO and shutter speed sliders</b> - If Camera2 API is used, and a non-auto ISO mode is selected, instead of the exposure
|
||
|
|
compensation sliders, two sliders will appear allowing you to control the ISO more finely, and (if supported) the exposure
|
||
|
|
(shutter speed) time.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<b>Manual white balance</b> - If Camera2 API is used, and manual white balance is enabled (from the popup menu), then this
|
||
|
|
will also show a slider allowing you to control the white balance temperature.

|
||
|
|
various options:</p><ul>
|
||
|
|
<li><b>Flash</b> - Typical options are off, auto, on and torch mode. For front cameras without a real flash, flash and torch options
|
||
|
|
will be available which instead work by making the screen light up (note, front screen flash "auto" is only available with Camera2 API).</li>
|
||
|
|
<li><b>Focus</b> - Controls the focusing method used. Available options depend on your device. These may include:<ul>
|
||
|
|
<li><img src="focus_mode_continuous_picture.png" alt="Continuous focus icon" width="32" height="32"><b>Continuous (default)</b> -
|
||
|
|
The camera focuses continuously. This is generally the best mode - the preview will usually always be in focus, and taking photos
|
||
|
|
is quick when the preview is already in focus. Note that you can still manually focus by touching the screen.
|
||
|
|
</li>
|
||
|
|
<li><img src="focus_mode_auto.png" alt="Auto focus icon" width="32" height="32"><b>Auto</b> -

A slider appears allowing you to manually control the focus distance (only available if Camera2
|
||
|
|
API is used). Also see the options "Focus assist" and "Focus peaking" under Settings/Camera preview/
|
||
|
|
which may be useful when using manual focus.

|
|
<li><b>STD</b> - Standard operation: takes a single photo.</li>
|
||
|
|
<li><b>NR</b> - Enables <a href="#noise_reduction">Noise Reduction</a> mode. (Only available on some devices,
|
||
|
|
and if Camera2 API is used.)</li>
|

|
|
<li><b>DRO</b> - Enables <a href="#dro">Dynamic Range Optimisation</a> mode.</li>
|
||
|
|
<li><b>HDR</b> - Enables <a href="#hdr">High Dynamic Range</a> mode.</li>
|
||
|
|
<li><b>Pano</b> - Enables <a href="#pano">Panorama</a> mode.</li>
|
||
|
|
<li><b>[]]]</b> - Enables Fast Burst mode. Takes multiple images in quick succession. (Only available on some
|
||
|
|
devices, and if Camera2 API is used.) In this mode, you can change the number of photos to take from the
|
||
|
|
popup menu.</li>
|
||
|
|
<li><b>Expo {}</b> - Enables Auto Exposure Bracketing (AEB) mode. Takes multiple images at different exposure
|
||
|
|
levels. See Settings/"Photo settings" for options to control the number of images and stops. These images can
|
||
|
|
be processed in other applications to create HDR images. For Android, you can try my own
|
||
|
|
<a href="https://play.google.com/store/apps/details?id=uk.org.opencamera.vibrancehdr">Vibrance HDR</a>.</li>
|
||
|
|
<li><b>Focus {}</b> - Enables <a href="https://en.wikipedia.org/wiki/Bracketing#Focus_bracketing">Focus Bracketing</a>
|
||
|
|
mode. (Only available on some devices, and if Camera2 API is
|
||
|
|
used.) This mode takes a series of photos each with a different focus distance. Two sliders appear, allowing you
|
||
|
|
to change the "source" and "target" focus distance. In this mode, you can change the number of photos to take from
|
||
|
|
the popup menu, and the option "Add infinite distance" if enabled will mean an extra photo is taken, at infinite focus distance.
|
||
|
|
Also on the popup menu, enabling "Auto source" will mean that the "source" focus distance will be set automatically via
|
||
|
|
continuous focus (or touching to focus will also select the source focus distance in this mode). Manually adjusting the
|
||
|
|
source focus distance slider will exit "Auto source" mode.
|
||
|
|
Focus bracketing is typically used with
|
||
|
|
<a href="https://en.wikipedia.org/wiki/Focus_stacking">Focus stacking</a> software to merge the images into a single
|
||
|
|
photo. Note that whilst taking a set of focus bracketed photos, you can cancel the set by pressing the "take photo"
|
||
|
|
button again. Also see the options "Focus assist" and "Focus peaking" under Settings/Camera preview/
|
||
|
|
which may be useful when adjusting the focus distances.</li>
|
||
|
|
<li><b>X- modes</b> - These extension modes enable device specific algorithms or effects that manufacturers have exposed to
|
||
|
|
third party applications (via Android's camera extensions API) (requires Android 12; only available on some devices,
|
||
|
|
and if Camera2 API is used).
|
||
|
|
<ul>
|
||
|
|
<li><b>X-Auto:</b> Allows the device to choose which algorithm to use based on the current scene. Note this differs to
|
||
|
|
"STD" mode in that it allows the use of the other camera extensions e.g. Night mode for low light scenes.</li>
|
||
|
|
<li><b>X-Night:</b> Improves image quality under low light conditions.</li>
|
||
|
|
<li><b>X-Bokeh:</b> Blurs the background of photos. This is typically intended when taking portraits of people.</li>
|
||
|
|
<li><b>X-Bty:</b> Face retouch or "beauty", applies cosmetic effects to people's faces.</li>
|
||
|
|
</ul>
|
||
|
|
Note many features may be unavailable when using an extension mode, including flash and manual controls.
|
||
|
|
</li>

||
|
|
</ul></li>
|
||
|
|
<li><b>Auto-level</b> - Enable the auto-level feature for photos (see
|
||
|
|
<a href="#auto_stabilise">below</a>). (Only available if the device has enough memory.)</li>
|
||
|
|
<li><b>Aperture</b> - Allows changing the current camera aperture. Large numbers mean smaller aperture, which means less
|
||
|
|
light is allowed into the camera. (Only available on some devices, and if Camera2 API is used.)</li>
|

|
|
<li><b>Camera resolution</b> - Change the photo resolution (also available under Settings/Photo

Settings/"Video resolution".</li>
|
||
|
|
<li><b>Speed</b> - This allows you to record video at either a faster rate (time lapse) or slower
|
||
|
|
rate (slow motion). Note that slow motion is only available on some devices, and requires
|
||
|
|
Camera2 API to be enabled. Also note that sound is not recorded in time lapse or slow motion
|

<p>All mobile phone cameras will rotate the photo depending on the orientation of the camera, but only to the nearest 90 degrees - so the
|
||
|
|

|
||
|
|
photos so they are perfectly level, so your shots come out looking perfectly level every time!</p>

</a></p>
|
||
|
|
|
||
|
|
<p>The above shows a rather exaggerated example - in practice, you can probably take better photos, but this feature ensures they
|
||
|
|
come out perfectly level, without you having to edit them afterwards in a photo editor. Of course you won't always want this -
|
||
|
|
perhaps you're going for artistic 45-degree shots - so this is an option. By default it is disabled. To enable, open the
|
||
|
|
<a href="#user_interface">Popup menu</a>, and enable "Auto-level". Note that this feature is memory intensive - it will not be available
|
||
|
|
on devices with low memory. Even where it is available, the performance of taking photos will be
|
||
|
|
slower.</p>
|
||
|
|
|
||
|
|
<p>Also note that the feature reduces the available space in the image - because rotating an image
|
||
|
|
makes it no longer fit into a rectangular image, so we have to crop it. So it's still advisable
|
||
|
|
to try to hold the camera reasonably level when using this feature.
|
||
|
|
When auto-level is enabled, an on-screen rectangle will display the frame of the resultant
|
||
|
|
rotated photo (note that this won't necessarily be 100% accurate depending on device/resolution,
|
||
|
|
in the same way that normally the preview frame may not perfectly match the resultant photo -
|
||
|
|
this will especially be true if Settings/Camera preview/"Preview size" is set to
|
||
|
|
"Maximise preview size".</p>

|
||
|
|
|
||
|
|
<p>In Noise Reduction photo mode, Open Camera takes a burst of photos which are then automatically merged, to improve photo quality.
|
||
|
|
This is particularly useful in low light scenes to reduce noise.

<!--The image below shows an example with one of the input burst photos on the left, and the resultant merged photo on the right:-->

|
|
||
|
|
<p>Some things to note about Open Camera's NR feature:</p>
|
||
|
|
<ul>
|
||
|
|
<li>In dark scenes, NR will also apply pixel binning, merging 4 pixels into 1 to reduce noise. Therefore in such cases , the
|
||
|
|
resultant photo resolution will be halved in width and height.</li>
|
||
|
|
<li>In bright scenes where there is a high dynamic range, NR mode will perform better than Standard at capturing the dynamic range.
|
||
|
|
This is similar to what Open Camera's <a href="#hdr">HDR</a> mode can achieve. Also see <a href="#nr_vs_hdr">NR vs HDR</a>.</li>
|
||
|
|
<li>Taking photos with NR is significantly slower than regular photos.</li>
|
||
|
|
<li>Although Open Camera applies auto-alignment to the images, it's still best to try to hold your device steady while the photo is
|
||
|
|
being taken. Aside from reducing the risk of ghosting effects, the more steady the camera is, the more effective the noise reduction
|
||
|
|
algorithm is in reducing noise and enhancing detail.</li>
|
||
|
|
<li>If you have a Google Pixel with Pixel Visual Core, you should get Google's HDR+ photos when using Open Camera's Standard photo mode, so there
|
||
|
|
is generally little benefit to using Open Camera's NR mode on these devices. See "Does Open Camera support HDR+" in the
|
||
|
|
<a href="#faq">FAQ</a> for more details.</li>
|
||
|
|
<li>If the photo mode "X-Night" is available, this may get better results for low light scenes.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>In Noise Reduction photo mode, an additional "NR mode" option will appear on the popup mode. This defaults to Normal, but
|
||
|
|
you can change to "Low Light" mode, which further improves results in dark scenes. If Open Camera detects poor light in this
|
||
|
|
mode, it will take a burst of images for a duration of around 5 seconds. For best results, use a tripod, or try to hold the
|
||
|
|
camera as steady as possible.</p>

<p><a name="dro"><b>DRO</b></a></p>
|
||
|
|
|
||
|
|
<p>Dynamic Range Optimisation (DRO) is a technique that optimises the dynamic range available in the image. In particular, dark
|
||
|
|
regions will have their brightness boosted to bring out the detail. This mode is useful for capturing scenes with a wide range
|
||
|
|
of brightness (e.g., on a bright sunny day) as well as being useful to automatically optimise photos in low light scenes. Also
|
||
|
|
see <a href="#dro_vs_hdr">DRO vs HDR</a>.</p>

|
|
<p><a name="hdr"><b>HDR</b></a></p>
|
||
|
|
|
||
|
|
<p>High Dynamic Range Imaging (HDR) is a technique where the camera takes multiple shots at different exposures, and combines them
|
||
|
|
into a single image. A typical problem in photography is that a scene may contain a brightness range that is wider than what can be
|
||
|
|
captured in a single shot. Varying the exposure (whether by touching on the screen, or exposure compensation or manual exposure) might
|
||
|
|
make darker regions brighter, but leave other areas over-exposed. Or reducing the exposure to prevent over-exposure may result in
|
||
|
|
the rest of the scene being too dark. HDR uses an algorithm to combine the best parts of each image, and adjusts the colors so that
|
||
|
|
the full range of brightness values are captured in the scene:</p>

<p>The left set of three images show the individual exposures, the right the final HDR image.</p>
|

|
||
|
|
<p>Some things to note about Open Camera's HDR feature:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Taking photos with HDR is significantly slower than regular photos (although note that HDR will give much faster performance if Camera2 API is enabled, see Settings - not all devices support this).</li>
|
||
|
|
<li>HDR isn't so good for scenes with movement, due to combining an image from multiple shots. Open Camera does apply "deghosting"
|
||
|
|
to reduce the problem, but this isn't perfect.</li>
|
||
|
|
<li>Although Open Camera applies auto-alignment to the images, it's still best to try to hold your device steady while the photo is
|
||
|
|
being taken.</li>
|
||
|
|
<li>HDR can sometimes result in less accurate color reproduction (due to trying to estimate the colors from multiple exposures).</li>
|
||
|
|
<li>Some camera apps use "HDR" to mean "apply a whacky-looking filter". Whilst HDR filters can be used to apply a rather
|
||
|
|
unreal or vivid image, for now Open Camera's HDR is more geared towards capturing the range of exposures. Also note that many camera
|
||
|
|
apps that advertise "HDR" don't even make use of multiple images - this is more a case of filtering, than HDR.</li>
|
||
|
|
<li>If you have a Google Pixel with Pixel Visual Core, you should get Google's HDR+ photos when using Open Camera's Standard photo mode, so there
|
||

<p><a name="dro_vs_hdr"><b>DRO vs HDR</b></a></p>
|
||
|
|
|
||
|
|
<p>Both DRO and HDR share in common that they are ways to handle wide ranges of brightness. They each have their pros and cons:</p>
|
||
|
|
<ul>
|
||
|
|
<li>DRO requires only a single image from the sensor, so shots are fast to take, and fine for scenes with movement, unlike HDR.</li>
|
||
|
|
<li>Photos will still take longer to process compared with Standard photo mode, but it will still be faster than HDR.</li>
|
||
|
|
<li>HDR will in general be better at scenes with a high range of brightness values. It can take advantage of the information from
|
||
|
|
three separate images, rather than reprocessing a single image.</li>
|
||
|
|
</ul>

|

|
|
<p><a name="nr_vs_hdr"><b>NR vs HDR</b></a></p>
|
||
|
|
|
||
|
|
<p>In scenes with high dynamic range, HDR should do better at capturing the high dynamic range (although NR should still be better
|
||
|
|
than Standard photo mode). Though NR still has the advantage that it is less prone to ghosting and misalignment. NR is also better
|
||
|
|
suited to working in a wide range of scenes.</p>
|
||
|
|
|
||
|
|
<p>In summary: NR is better if you just want a "works best in most cases" option. HDR may be a better choice specifically in
|
||
|
|
scenes with high dynamic range, that also don't have movement in the scene.</p>

If you find it's taking photos too often unintentionally, or isn't responding to your sounds, try adjusting this option.</p>
|
||
|
|
|
||
|
|
<p><b>Bluetooth LE remote control</b> - Open Camera supports connecting to some specific "smart housing" cases via the
|
||
|
|
options in these settings. See "Remote device type" for supported types. At the time of writing, only one make/model
|
||
|
|
is supported. Once connected via Bluetooth, it should be possible to control Open Camera from the device.
|
||
|
|
The on-screen display of Open Camera will also display information from the housing (temperature and depth).</p>
|
||
|
|
|
||
|
|
<p><b>Lock photo/video orientation</b> - Normally the orientation of the photo/video will be rotated by some multiple of
|
||
|
|
90 degree such that the orientation looks right - e.g. if your device is held in portrait, the resultant image/video will
|
||
|
|
be in portrait. This option allows fixing the camera to either be in portrait or landscape. Note that if
|
||
|
|
<a href="#auto_stabilise">auto-level</a> is also enabled, it will have the effect of aligning photos to the nearest
|
||
|
|
90 degrees.</p>

<p><a name="save_location"><b>Save location</b></a> - Select the folder to store the resultant photos or videos in.</p>
|
||
|
|
<ul>
|
||
|
|
<li><b>On Android 9 or earlier:</b> This opens a file dialog. Click on a folder (or "Parent Folder") to navigate through
|
||
|
|
the filesystem. Select "New Folder" to create a new folder in the currently displayed folder. Select "Use Folder"
|
||
|
|
to choose the currently displayed folder. Note that on Android, there are some folders that cannot be written
|
||
|
|
to - Open Camera will display a message if you try to use one of these folders.</li>
|
||
|
|
<li><b>On Android 10 or later:</b> This opens a dialog to type the name of the folder. This
|
||
|
|
will be a subfolder of DCIM on your internal storage. You can specify subfolders with the "/"
|
||
|
|
character. For example, specifying Camera/holiday will save inside DCIM/Camera/holiday/
|
||
|
|
on your internal storage.</li>
|
||
|
|
<li><b>If "Storage Access Framework" is enabled</b>: Then on any Android version, this option
|
||
|
|
will show up the Android standard file chooser - navigate to the desired folder, and click "SELECT" or
|
||
|
|
"ALLOW ACCESS" (wording varies depending on Android version).</li>
|
||
|
|
</ul>
|
||
|
|
<p>Once you have specified a new save location, you can long press on the Gallery icon to quickly switch between recent save
|
||
|
|
locations. If you want to save to an SD card, see "How can I save to my external SD card?" under the <a href="#faq">FAQ</a>.</p>
|
||
|
|
|
||
|
|
<p><b>Storage Access Framework</b> - If selected, Open Camera will instead use the Android
|
||
|
|
<a href="https://developer.android.com/guide/topics/providers/document-provider.html">Storage Access Framework</a>. This
|
||
|
|
has some advantages, such as using the standard Android file picker, and being the only way to save to SD cards on Android 5+.
|
||
|
|
In some cases it may allow you to save to cloud or local storage providers provided by other apps or services.
|
||
|
|
Furthermore on Android 10+, it is the only way to save outside of the DCIM/ folder.</p>
|
||
|
|
|
||
|
|
<!--Enter the folder to store the photos in. This can be either a relative path (e.g.,
|
||
|
|
OpenCamera or even something like MyPics/Camera) in which case the folder will be located inside the "DCIM"
|
||
|
|
folder (usually something like /sdcard/DCIM/ ). For more advanced users, if the folder name starts with "/", then
|
||
|
|
it indicates the full absolute path (e.g., /sdcard/Pictures/Photos ). Note that folder names are case sensitive.
|
||
|
|
OpenCamera will attempt to create the folder (and any sub-folders as required) if it doesn't exist. If you specify
|
||
|
|
a path that you don't have write permissions for, then OpenCamera will fail to save images/videos (and this will
|
||
|
|
be reported when you try to take a photo or video).-
|
||
|
|
You can also use this option to save to an external SD card, though unfortunately the path varies depending on the
|
||
|
|
device, so you'll have to look this up yourself (it's usually something inside /mnt/ ).-->
|
||
|
|
|
||
|
|
<p><b>Save photo prefix</b> - This option allows you to customise save filenames for photos.</p>
|
||
|
|
|
||
|
|
<p><b>Save video prefix</b> - This option allows you to customise save filenames for videos.</p>
|
||
|
|
|
||
|
|
<p><b>Time format for filename</b> - By default, Open Camera uses the local timezone for the save filenames, but you
|
||
|
|
can also select UTC <a href="https://en.wikipedia.org/wiki/Coordinated_Universal_Time">(Coordinated Universal Time / Zulu Time)</a>.
|
||
|
|
For the latter option, a "Z" will be appended to the filename (e.g., "IMG_20160524_155116Z.jpg"). The Z (Zulu) suffix
|
||
|
|
is a standard convention for identifying UTC timestamps.</p>
|
||
|
|
|
||
|
|
<p><b>Use milliseconds in filename</b> - If enabled, the datestamp used for filenames will include
|
||
|
|
milliseconds (e.g. "IMG_20250312_210531.350.jpg")</p>
|
||
|
|
|
||
|
|
<p><b>Allow vibration feedback</b> - Whether to allow haptic vibration feedback, for example when
|
||
|
|
adjusting some controls. Note this also requires touch interactions to be enabled in your
|
||
|
|
device's settings, this is usually under the "Sound and vibration" settings or similar.</p>
|
||
|
|
|
||
|
|
<p><b>Show camera when locked</b> - If you have a lock screen on your device (e.g., PIN to unlock), if this option
|
||
|
|
is enabled Open Camera will show above the lock screen - i.e., if locked, you won't have to enter the PIN to
|
||
|
|
use Open Camera. The device still needs to be unlocked in order to go to the Settings or Gallery. If you would
|
||
|
|
prefer Open Camera to always be unavailable when your device is locked, this option should be disabled.</p>
|
||
|
|
|
||
|
|
<p><b>Perform auto-focus on startup</b> - Whether Open Camera should auto-focus when starting the camera. Some devices
|
||
|
|
have a bug where the flash turns on when this happens, so a workaround is to disable this option.</p>
|
||
|
|
|
||
|
|
<p><b>Allow long press actions</b> - Some icons support a "long press" action (touching and holding on the icon). For example,
|
||
|
|
long press on the gallery icon to change the save location, or in some cases long press on the shutter icon will enable a
|
||
|
|
burst. If you prefer, you can disable these long press actions.</p>
|
||
|
|
|
||
|
|
<p><b>Calibrate level angle</b> - The options <a href="#auto_stabilise">Auto-level</a>, "Show angle" and "Show angle line"
|
||
|
|
rely on your device's ability to detect which orientation it's being held (the accelerometer). On some device's this might not
|
||
|
|
be calibated correctly. If so, you can use this option to calibrate the acceleromer (or reset the calibration back to the
|
||
|
|
default behaviour).</p>
|
||
|
|
|
||
|
|
<p><b>Camera preview...</b> - Select to access the following controls:</p>
|
||
|
|
|
||
|
|
<p><b>Preview size</b> - By default, Open Camera matches the aspect ratio of the preview (the image that is
|
||
|
|
displayed on the phone/tablet's display) with that of the photo resolution ("Match photo size (WYSIWYG)" mode). The
|
||
|
|
advantage is that what you see in the preview will match what will be in the resultant photo
|
||
|
|
("What-You-See-Is-What-You-Get") - though this may mean you will have "black bars" on the display in order to do
|
||
|
|
this. If instead you select "Maximise preview size", then the camera preview will be as large as possible, trying to
|
||
|
|
fill the available space. However if the resolution of the photo is a different aspect ratio to that of your device,
|
||
|
|
this will result in the preview being cropped. In video mode, the preview is always in WYSIWYG mode.</p>
|
||
|
|
<ul>
|
||
|
|
<li>Note that Android 4.4.3 <a href="https://code.google.com/p/android/issues/detail?id=70830">introduced a bug</a>
|
||
|
|
which means that the aspect ratio will be wrong if you select "Maximise preview size" (i.e., the preview will look
|
||
|
|
squished). To avoid this problem, stick with "Match photo size".</li>
|
||
|
|
<li>Also note that even in "Match photo size" mode, on some devices and resolutions, it may not be possible to match
|
||
|
|
the preview to the resultant photo/video exactly; in such cases, Open Camera will try to match as closely as
|
||
|
|
possible.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Ghost image</b> - You can overlay a previous photo. This is useful for aligning photos (e.g., for stop
|
||
|
|
motion animation). This can also be used to create a custom "grid", by selecting an image with transparency.</p>
|
||
|
|
<ul>
|
||
|
|
<li><b>Last photo taken</b> - When you take a photo, a ghost of that photo will be displayed. The ghost is
|
||
|
|
reset either by leaving and returning to Open Camera, switching between photo/video modes, or turning
|
||
|
|
this option off.</li>
|
||
|
|
<li><b>Selected image</b> - Select a specific image on your device to be displayed as a ghost
|
||
|
|
Note that for this option, the ghost image will not be displayed if Open Camera is running
|
||
|
|
when your device is locked. If the image doesn't show at all, it may be that Open Camera was unable to
|
||
|
|
load the selected image.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Ghost image opacity</b> - If a "Ghost image" is selected, this option controls how transparent/opaque the ghost
|
||
|
|
image should be drawn with.</p>
|
||
|
|
|
||
|
|
<p><b>Focus assist</b> - If enabled, this will show a zoomed in view on the camera preview when in manual focus mode, and you
|
||
|
|
are changing the manual focus distance. Similarly in focus bracketing mode, the preview will zoom in when changing the focus
|
||
|
|
distances to bracket between. Note not supported when recording video.</p>
|
||
|
|
|
||
|
|
<p><b>Show zoom</b> - Whether to display the current zoom level of the camera (when zoomed in).</p>
|
||
|
|
|
||
|
|
<p><b>Show angle</b> - Whether to display the orientation angle of the device's camera.</p>
|
||
|
|
|
||
|
|
<p><b>Show angle line</b> - Whether to display a horizontal "level" line that visually indicates the orientation of the device.</p>
|
||
|
|
|
||
|
|
<p><b>Show pitch lines</b> - Whether to display horizontal pitch lines that visually indicate the pitch of the device.</p>
|
||
|
|
|
||
|
|
<p><b>Angle highlight color</b> - This controls the color to be used for the angle display and "level" line when the camera is nearly
|
||
|
|
level; and also for the 0 degree pitch line when the camera is held at nearly zero pitch.</p>
|
||
|
|
|
||
|
|
<p><b>Show compass direction</b> - Whether to display the compass direction of the device's camera.</p>
|
||
|
|
|
||
|
|
<p><b>Show compass direction lines</b> - Whether to display vertical lines that visually indicate the compass direction of the device.</p>
|
||
|
|
|
||
|
|
<p><b>Show battery</b> - Whether to display the current battery level.</p>
|
||
|
|
|
||
|
|
<p><b>Show time</b> - Whether to display the current time.</p>
|
||
|
|
|
||
|
|
<p><b>Show camera ID</b> - For devices with multiple front/back cameras. Whether to display the currently used camera ID.
|
||
|
|
This will be a value starting from 0, that distinguishes between the different cameras on your device.</p>
|
||
|
|
|
||
|
|
<p><b>Show free memory</b> - Whether to display the remaining storage space of the device.</p>
|
||
|
|
|
||
|
|
<p><b>Show ISO</b> - If selected, the current ISO, exposure time and frame rate (FPS) will be displayed (only available if Camera2
|
||
|
|
API is used). The text will be shown in red when the auto-exposure routine is scanning.</p>
|
||
|
|
|
||
|
|
<p><b>Show a histogram</b> - Allows displaying an on-screen histogram (only available if Camera2 API is used). Note that the
|
||
|
|
histogram reflects the currently display on-screen preview, and will not necessarily be accurate for the final resultant photograph,
|
||
|
|
especially if modes such as NR, DRO, HDR are used. Also note that displaying a histogram may use more battery.
|
||
|
|
The follow options are available:</p>
|
||
|
|
<ul>
|
||
|
|
<li>RGB Colors - Displays a histogram for each color channel.</li>
|
||
|
|
<li>Luminance - The brightness is computed as a weighted average of the RGB components: 0.299*R + 0.587G + 0.114*B.</li>
|
||
|
|
<li>Value - The brightness is computed as the maximum of the RGB components.</li>
|
||
|
|
<li>Intensity - The brightness is computed as an unweighted average of the RGB components.</li>
|
||
|
|
<li>Lightness - The brightness is computed as an average of the minimum and maximum of the RGB components.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Show zebra stripes</b> - Allows displaying on-screen zebra stripes (also known as
|
||
|
|
<a href="https://en.wikipedia.org/wiki/Zebra_patterning">zebra patterning</a>) to show whether the
|
||
|
|
image is over-exposed (only available if Camera2 API is used). Note when using photo modes NR and HDR,
|
||
|
|
a region that is shown as over-exposed on-screen may not necessarily be over-exposed in the resultant image,
|
||
|
|
since these modes are able to better handle a high dynamic range. Also note that enabling zebra stripes
|
||
|
|
may use more battery.</p>
|
||
|
|
|
||
|
|
<p><b>Zebra stripes foreground/background colour</b> - If "Show zebra stripes" is enabled, these options allow you to
|
||
|
|
choose the colours of the stripes.</p>
|
||
|
|
|
||
|
|
<p><a name="focus_peaking"><b>Focus peaking</b></a> - Allows displaying on-screen highlights to indicate edges (contours) that are in-focus
|
||
|
|
(only available if Camera2 API is used). This is particularly useful in conjunction with manual focus mode, to help show
|
||
|
|
which regions of the image are in focus. Note that enabling focus peaking may use more battery.</p>
|
||
|
|
|
||
|
|
<p><b>Focus peaking color</b> - This controls the color to be used for the highlights when "Focus peaking" is enabled.</p>
|
||
|
|
|
||
|
|
<p><b>Show audio level meter</b> - If selected, when recording video an on-screen meter will display the current audio level.</p>
|
||
|
|
|
||
|
|
<p><b>Show a grid</b> - Whether to display one of a choice of grids on the camera preview. Grids are useful in photography to help
|
||
|
|
compose your image. Options are:</p>
|
||
|
|
<ul>
|
||
|
|
<li>3x3 - helps with applying the <a href="https://en.wikipedia.org/wiki/Rule_of_thirds">rule of thirds</a>.</li>
|
||
|
|
<li>Phi 3x3 - 3x3 grid with ratios 1:0.618:1.</li>
|
||
|
|
<li>4x2</li>
|
||
|
|
<li>Crosshair</li>
|
||
|
|
<li>Golden - displays a <a href="https://en.wikipedia.org/wiki/Golden_spiral">Golden spiral</a> (or technically,
|
||
|
|
a Fibonacci spiral). You can use this to improve your photography.</li>
|
||
|
|
<li>Golden Triangles</li>
|
||
|
|
<li>Diagonals</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Show a crop guide</b> - A crop guide is a rectangle displayed on-screen, which has the specified aspect ratio
|
||
|
|
(if different to the photo/video aspect ratio). This is useful if you plan to crop the resultant photos or videos
|
||
|
|
to a particular aspect ratio. For photos, the crop-guide requires "Preview size" to be set to WYSIWYG mode.</p>
|
||
|
|
|
||
|
|
<p><b>Show thumbnail animation</b> - Whether to display the moving thumbnail animation when taking a photo.</p>
|
||
|
|
|
||
|
|
<p><b>Show border when taking photo</b> - Whether to display a border effect when taking a photo.</p>
|
||
|
|
|
||
|
|
<p><b>Rotate preview</b> - this option rotates the on-screen preview by 180 degrees (i.e., upside down). Most users
|
||
|
|
won't ever need this, but this option can be useful if you are using Open Camera with equipment such as zoom lenses
|
||
|
|
which invert the image. Note that this doesn't rotate the resultant photos/videos - you'll still have to rotate those
|
||
|
|
yourself afterwards - but this will correct the preview so that you can still see what you are shooting properly.</p>
|
||
|
|
|
||
|
|
<p><b>On screen GUI...</b> - Select to access the following controls:</p>
|
||
|
|
|
||
|
|
<p><b>UI placement</b> - Allows you to choose between various layouts for the on-screen user interface icons.</p>
|
||
|
|
|
||
|
|
<p><b>Immersive mode</b> - Allows you to choose between various modes which affect the behaviour of the user-interface, in order to
|
||
|
|
make it more immersive:</p>
|
||
|
|
<ul>
|
||
|
|
<li><b>Off (default)</b> - Don't use immersive mode, and on-screen virtual navigation buttons are always visible.</li>
|
||
|
|
<li><b>Hide on-screen virtual navigation buttons</b> - After a short delay, any on-screen virtual navigation buttons will disappear.<li>
|
||
|
|
<li><b>Hide GUI</b> - After a short delay, any on-screen virtual navigation buttons will disappear, along with most of the GUI buttons.
|
||
|
|
To exit this immersive mode, either touch on-screen, or swipe in from the top/bottom sides when the device is held in landscape (or
|
||
|
|
left/right sides if held in portrait).</li>
|
||
|
|
<li><b>Hide everything</b> - Same as "Hide GUI", but when in immersive mode everything will disappear except the camera preview. This
|
||
|
|
mode probably isn't useful for most people (since you need to exit immersive mode even to take a photo), but is available if you wish
|
||
|
|
to only have the preview showing.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Show face detection icon</b> - Whether to display an on-screen icon for enabling or disabling face detection. See

|
|
<a href="#auto_stabilise">Auto-level feature</a> above for more details.</p>
|
||
|
|
|
||
|
|
<p><b>Show flash icon</b> - Whether to display an on-screen icon for cycling through flash modes. If this is enabled, then
|
||
|
|
flash modes won't show on the popup menu. Also note that it is not possible to enable the torch with this method.</p>
|
||
|
|
|

<p><b>Show auto white balance lock icon</b> - Whether to display an on-screen icon for locking or unlocking auto white
|
||
|
|
balance.</p>
|
||
|
|
|
||
|
|
<p><b>Show auto exposure lock icon</b> - Whether to display an on-screen icon for locking or unlocking auto exposure.</p>
|

|
<p><b>Show zoom slider controls</b> - Whether to display to a slider to control zoom.</p>
|
||
|
|
|
||
|
|
<p><b>Show "Take Photo" icon</b> - Whether to display the shutter button
|
||
|
|
for taking a photo (or recording video). Uncheck if you'd
|
||
|
|
rather take photos by other methods (e.g., if your device has a hardware shutter button, or using the volume keys).</p>
|
||
|
|
|
||
|
|
<p><b>Show on-screen messages</b> - Open Camera will sometimes display temporary on-screen text with information (in some
|
||
|
|
cases using "toasts"). This option can be used to disable them.</p>
|
||
|
|
|
||
|
|
<p><b>Show What's New dialog</b> - When updating to a major new version, Open Camera displays a dialog explaining the new
|
||
|
|
features and other options. You can disable this dialog from being displayed if you prefer.</p>
|
||
|
|
|
||
|
|
<p><b>Multiple cameras icon</b> - This option only shows on devices that allow explicitly switching between more than
|
||
|
|
one front and/or back cameras. When
|
||
|
|
enabled (the default), such devices will have two on-screen icons: one to switch between front/back cameras, and another
|
||
|
|
to switch between the multiple front or back cameras (and if supported, selecting a physical lens). If this option is disabled, only a single icon will show, which
|
||
|
|
will cycle between all cameras (selecting a specific lens is not possible with this method).</p>
|
||
|
|
|
||
|
|
<p><b>Keep display on</b> - Whether to force keeping the screen display on, while the main Open Camera UI is active.</p>
|

<p><b>Photo and Video Settings:</b></p>
|

|
|
|
||
|
|
<p><b>Photo settings</b> - Select to access the following controls:</p>
|
||
|
|
|
||
|
|
<p><b>Camera resolution</b> - Select the resolution of photo images taken by the camera.</p>
|
||
|
|
<ul>
|
||
|
|
<li>If <a href="#auto_stabilise">auto-level</a> is enabled, images will in general come out as a
|
||
|
|
slightly lower resolution (due to the rotation and cropping that's required).
|
||
|
|
</li>
|
||
|
|
<li>Note that in some photo modes, the actual photo mode may be different to that selected here.
|
||
|
|
For example, advanced photo modes such as HDR, NR, Fast Burst, Expo Bracketing may have a
|
||
|
|
maximum supported resolution - if the resolution selected here is too high, the largest
|
||
|
|
allowed resolution will instead be used. To see the resolution currently used (or to change
|
||
|
|
it), see the "Camera resolution" setting on the popup menu.
|
||
|
|
</li>
|
||
|
|
<li>The resolution setting is ignored altogether in Panorama mode.
|
||
|

|
|
|
||
|
|
<p><b>Optimise focus for...</b> - How to optimise the behaviour when using continuous focus mode.
|
||
|
|
Latency means take the photo as soon as possible - on modern devices, the result will typically
|
||
|
|
already be in focus. If this isn't the case, select "Quality" to ensure that the scene is focused.
|
||
|
|
(Requires Android 12+ and Camera2 API; on other devices this will default to "Quality".)</p>
|
||
|
|
|
||
|
|
<p><b>Save preview shots</b> - When enabled, a short video will be saved alongside each photo,
|
||
|
|
containing shots from the moment before the photo was taken. Not supported for expo bracketing,
|
||
|
|
focus bracketing or panorama modes. Typically the video will contain 12 shots, over approximately
|
||
|
|
just over a second. Note that this is not intended to be a 30fps (or better) video, rather the intent
|
||
|
|
is to save a burst of photos. You can use various gallery apps to export individual frames (usually by
|
||
|
|
selecting "Edit" when viewing the video).
|
||
|
|
(Requires Android 8+ and Camera2 API.)
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p><b>Image quality</b> - The image quality of saved JPEG (including Ultra HDR) or WebP images. Higher means better quality, but the image files will take up
|
||
|
|
more storage space. Note that 100% does not necessarily mean there is no lossy compression, rather that there is minimum
|
||
|
|
compression. Also note this option has no effect if "Image format" is set to PNG.</p>
|
||
|
|
|
||
|
|
<p><b>Image format</b> - The image file format for saving photos:</p>
|
||
|
|
<ul>
|
||
|
|
<li>JPEG - This is the fastest option. Also note that only JPEG and Ultra HDR JPEG support saving various photo
|
||
|
|
metadata (Exif), including camera details, location, and artist/copyright tags.</li>
|
||
|
|
<li>Ultra HDR JPEG - This is a format that saves additional high dynamic range data, for viewing on
|
||
|
|
HDR displays, but is backwards compatible with JPEG (so resultant images can still be viewed by older
|
||
|
|
JPEG viewers, and on standard non-HDR displays). (Requires Android 14+ and Camera2 API, and even then,
|
||
|
|
only available on devices that support Ultra HDR for third party applications.) This is not supported for
|
||
|
|
NR, HDR, Pano or "X-" extension photo modes - in these modes, images will be saved as regular JPEG.</li>
|
||
|
|
<li>WebP - This is an alternative (lossy) file format to JPEG. It offers smaller file sizes,
|
||
|
|
but saving takes longer, and some applications may not support WebP images. Note that WebP
|
||
|
|
images are generated by converting from a JPEG with 100% quality (since the Android camera API does not
|
||
|
|
have native WebP output).</li>
|
||
|
|
<li>PNG - This is a lossless format, but note that file sizes will be large, and saving will
|
||
|
|
take significantly longer. Note that this doesn't mean there will be absolute no loss in quality:
|
||
|
|
cameras on Android offer images in JPEG or RAW (DNG) file formats. When using PNG, Open Camera
|
||
|
|
receives the JPEG with the quality set to 100%, and converts to PNG - this means that there is minimal
|
||
|
|
lossy compression. The only way to have truly lossless is via RAW (see option below).</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><a name="raw"><b>RAW</b></a> - Only available if Camera2 API is used. If set to "Standard and DNG (RAW)", then photos
|
||
|
|
will also be saved in RAW (DNG) format. If set to "DNG (RAW) only" (requires Android 7), then photos
|
||
|
|
will only be saved in DNG format. DNG stands for
|
||
|
|
<a href="https://en.wikipedia.org/wiki/Digital_Negative">"digital negative"</a>, and contains the full
|
||
|
|
uncompressed and unprocessed information from your camera. Please note the following points:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Some gallery applications don't recognise DNG files - if this is the case, you won't even see them listed.
|
||
|
|
Either install a gallery application that does, or use specialised RAW viewer or editing tools.
|
||
|
|
Or transfer to a PC to use DNG editing applications there. Note that newer versions of Android
|
||
|
|
(7 onwards) seem to have better support for DNG images.</li>
|
||
|
|
<li>If your gallery application doesn't show DNG files, a file explorer application may also be useful,
|
||
|
|
to delete DNGs if you don't want them (DNGs take up a lot of space - and won't be deleted when you delete
|
||
|
|
the corresponding JPEG from a Gallery application).</li>
|
||
|
|
<li>Note that various processing options such as DRO photo mode, "Stamp photos" and <a href="#auto_stabilise">"Auto-level"</a> will only apply
|
||
|
|
to the JPEG images, and not the DNG images. This is not a bug - the DNGs represent the RAW output
|
||
|
|
of the camera device. This also means that these options have no relevance for photos in "DNG (RAW) only" mode, therefore such
|
||
|
|
options will not show on the popup menu.</li>
|
||
|
|
<li>Options to store extra Exif tags ("Store compass direction", "Artist", "Copyright") are only supported for
|
||
|
|
JPEG formats.</li>
|
||
|
|
<li>Some devices only support saving RAW images in the Standard or DRO photo modes. Higher end devices will also support saving RAW
|
||
|
|
images also in Expo Bracketing and Focus Bracketing modes, as well as HDR where "Save all images for HDR mode" is enabled.
|
||
|
|
The X- modes do not support saving RAW images.
|
||
|
|
The on-screen "RAW" icon will show if RAW is enabled for the current photo mode.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Allow RAW for expo bracketing</b> - If this option is disabled, the RAW images won't ever be saved in expo bracketing or HDR
|
||
|
|
photo modes.</p>
|
||
|
|
|
||
|
|
<p><b>Allow RAW for focus bracketing</b> - If this option is disabled, the RAW images won't ever be saved in focus bracketing photo
|
||
|
|
mode.</p>
|
||
|
|
|
||
|
|
<p><b>Noise Reduction original images</b> - When using <a href="#noise_reduction">Noise Reduction</a> mode, if
|
||
|
|
this option is enabled, then the input images from the burst of images taken will be saved, as well as the
|
||
|
|
final NR photo. You can choose to save either a single image from the burst, or all images. This may be useful
|
||
|
|
if you want to use external image stacking applications to merge the images. Note that these images will
|
||
|
|
typically be noisier than a typical photo from Standard mode, because the device's noise reduction algorithms
|
||
|
|
are disabled (this seems counter-intuitive, but in order to improve quality by merging multiple images, noise
|
||
|
|
reduction algorithms need to be applied after the merging, not before).
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p><b>Save all images for HDR mode</b> - When using <a href="#hdr">HDR</a> mode, if this option is enabled,
|
||
|
|
then the three base exposure images will be saved as well as the final HDR photo. This is useful if you want
|
||
|
|
to use external HDR applications (such as my own
|
||
|
|
<a href="https://play.google.com/store/apps/details?id=uk.org.opencamera.vibrancehdr">Vibrance HDR</a> for Android,
|
||
|
|
or various HDR applications for PC) to
|
||
|
|
create the final HDR image (although if you don't want Open Camera's HDR mode at all, you can instead use the
|
||
|
|
Exposure Bracketing Photo Mode). Note this will make saving slower, especially if options like "Stamp photos" or
|
||
|
|
<a href="#auto_stabilise">Auto-level</a> are also used.</p>
|
||
|
|
|
||
|
|
<p><b>HDR tonemapping</b> - When using <a href="#hdr">HDR</a> mode, the high dynamic range image needs to be converted
|
||
|
|
back to a regular image, using a process called tonemapping. This option allows you to choose some different
|
||
|
|
tonemapping algorithms.</p>
|
||
|
|
|
||
|
|
<p><b>HDR contrast enhancement</b> - When using <a href="#hdr">HDR</a> mode, in some (bright) scenes a local contrast
|
||
|
|
enhancement algorithm is applied to improve the look of the image. It also gives such images a look that is stereotypically
|
||
|
|
associated with "HDR". If you prefer not to apply this at all, you can change this option from "Smart" to "Off". Or you can
|
||
|
|
choose "Always" to have it applied in all cases.</p>
|
||
|
|
|
||
|
|
<p><b>Exposure Bracketing</b> - Specifies the total number of images to save in Exposure Bracketing Photo Mode
|
||
|
|
(Camera2 API only).</p>
|
||
|
|
|
||
|
|
<p><b>Exposure Bracketing Stops</b> - Specifies the number of stops to subtract/add from the "base"
|
||
|
|
exposure level to the darkest/brightest image, in Exposure Bracketing Photo Mode. An increase of 1
|
||
|
|
stop means a doubling of the amount of light. So a setting of "2", with 3 images, will produce
|
||
|
|
images with exposure set to [-2, 0, +2]. For 5 images, this will produce [-2, -1, 0, +1, +2].</p>
|
||
|
|
|
||
|
|
<p><b>Panorama auto-crop</b> - Normally <a href="#pano">panoramas</a> are cropped to give a rectangular result.
|
||
|
|
Disabling this option will show the full extent of the panorama, but will leave wavy black borders.</p>
|
||
|
|
|
||
|
|
<p><b>Panorama original images</b> - Whether to save the original shots in <a href="#pano">Panorama</a> mode. This can be useful
|
||
|
|
if you want to use a third party application to stitch the images together to create a panorama. Note that these original
|
||
|
|
images are always saved in PNG format. This option can also be useful for debugging purposes, to send me example images when
|
||
|
|
reporting problems with panorama - for this, it's best to select to include the debug XML file. Note the XML files will be
|
||
|
|
saved inside <small>Android/data/net.sourceforge.opencamera/files/</small>, and you'll typically need
|
||
|
|
a third party File Explorer application to see and delete XML files.</p>
|
||
|
|
|
||
|
|
<p><b>Front camera mirror</b> - Normally for front cameras, the preview will behave like a mirror, but resultant
|
||
|
|
photos will still be as the camera (or other people) view the scene. This option can be used to mirror the
|
||
|
|
resultant photo, so the resultant photo matches the mirrored image you see on the screen.</p>
|
||
|
|
|
||
|
|
<p><b>Remove device EXIF data</b> - Whether to remove device EXIF metadata from JPEG photos. Note that
|
||
|
|
this will not remove exif tags applied by other Open Camera settings that apply EXIF metadata (e.g.
|
||
|
|
location/geotagging, artist, copyright etc). Those other options are independent and will override this
|
||
|
|
setting. Also note that RAW/DNG and videos are not affected.</p>
|
||
|
|
|
||
|
|
<p><b>Artist</b> - If text is entered in this setting, then the text will be stored in the image's Exif metadata as the
|
||
|
|
"Artist" tag. Only supported for JPEG formats. Not supported for RAW photos (DNG format).</p>
|
||
|
|
|
||
|
|
<p><b>Copyright</b> - If text is entered in this setting, then the text will be stored in the image's Exif metadata as the
|
||
|
|
"Copyright" tag. Only supported for JPEG formats. Not supported for RAW photos (DNG format).</p>
|
||
|
|
|
||
|
|
<p><a name="stamp_photos"><b>Stamp photos</b></a> - Option to add a date and timestamp to the resultant photos. If "Store
|
||
|
|
location data" is enabled (see "Location settings" below), then the current location latitude
|
||
|
|
and longitude coordinates, and altitude, will also be stamped on the resultant photos (if the location is known).
|
||
|
|
Similarly for "Store compass direction". Note that if this option is enabled, then it will take
|
||
|
|
longer to save the photo. Also see "Video subtitles".</p>
|
||
|
|
|
||
|
|
<p><b>Datestamp format, Timestamp format</b> - If "Stamp photos" is enabled, these options allow
|
||
|
|
extra control over the date and time formatting. Also used for Video settings/"Video subtitles".</p>
|
||
|
|
|
||
|
|
<p><b>GPS stamp format</b> - If "Stamp photos" is enabled, this allows extra control over the GPS
|
||
|
|
formatting. Also used for Video settings/"Video subtitles".</p>
|
||
|
|
|
||
|
|
<!--<p><b>Use addresses</b> - If "Stamp photos" and "Store location data" is enabled, this allows the location
|
||
|
|
to be displayed on the resultant photo in the form of an address, either as well as or instead of GPS
|
||
|
|
coordinates. Similarly also used for Video settings/"Video subtitles".
|
||
|
|
An Internet connection is required for this to succeed.
|
||
|
|
Note that if enabled, this requires that your device transmits location data across the Internet to a third party
|
||
|
|
in order to convert GPS coordinates to an address (this uses the
|
||
|
|
<a href="https://developer.android.com/reference/android/location/Geocoder">Geocoder API</a>).
|
||
|
|
This feature provides no guarantees on availability or accuracy. Results are a best guess, and not

|
|
guaranteed to be meaningful or correct.
|
||
|

</p>-->
|
||
|
|
|
||
|
|
<p><b>Distance unit</b> - If "Stamp photos" is enabled, this controls whether to use metres (m) or
|
||
|
|
feet (ft) when recording the GPS altitude. Also used for Video settings/"Video subtitles".</p>
|
||
|
|
|
||
|
|
<p><a name="custom_text"><b>Custom text</b></a> - Here you can enter some text to be stamped onto resultant photos (e.g.,
|
||
|
|
this could be used for a copyright image). Note that if this option is enabled, then it will take
|
||
|
|
longer to save the photo. Also note that this option is only supported for photos, not video.</p>
|
||
|
|
|
||
|
|
<p><b>Font size</b> - Sets the font size used for text for options "Stamp photos" or
|
||
|
|
"Custom text".</p>
|
||
|
|
|
||
|
|
<p><b>Font color</b> - Sets the font color used for text for options "Stamp photos" or
|
||
|
|
"Custom text".</p>
|
||
|
|
|
||
|
|
<p><b>Text style</b> - Whether to render the text on the image with a shadow background effect, for
|
||
|
|
options "Stamp photos" or "Custom text".</p>
|
||
|
|
|
||
|
|
<p><b>Use alternative flash method</b> - (Camera2 API only.) Unfortunately many devices have poor support for the
|
||
|
|
Camera2 API. A common issue is poor flash behaviour (either flash doesn't fire, or photos are over or under exposed).
|
||
|
|
If so, enabling this option may help - this uses an alternative algorithm for flash (using the torch to simulate flash
|
||
|
|
as a workaround). Note that this is enabled by default for Samsung devices.</p>
|
||
|
|
|
||
|
|
<p><b>Enable dummy capture HDR/expo fix</b> - (Camera2 API only.) Enable this option if your device has problems taking photos
|
||
|
|
in HDR or Exposure Bracketing photo modes, specifically if some expo images come out with the same exposures. This option
|
||
|
|
takes an additional "dummy" image which may resolve such problems. Note that "Enable fast HDR/expo burst" (below) must
|
||
|
|
be enabled for this option to have an effect.</p>
|
||
|
|
|
||
|
|
<p><b>Enable fast HDR/expo burst</b> - (Camera2 API only.) Disable this option if your device has problems taking photos
|
||
|
|
in HDR or Exposure Bracketing photo modes (disabling this option will result in a longer delay between the photos being
|
||
|
|
taken, but may give more stable behaviour if your device is having problems with this).</p>
|
||
|
|
|
||
|
|
<p><b>Allow photos whilst recording video</b> - (Camera2 API only.) Some devices support taking photos whilst recording video,
|
||
|
|
but there's the problem that enabling such functionality make cause problems with regular video recording. If you have problems
|
||
|
|
recording video with Camera2 API enabled, try disabling this option.</p>
|
||
|
|
|
||
|
|
<!--<p><b>Use background thread</b> - Whether to process and save photo in the background. Normally this should
|
||
|
|
be left set to true for faster operation, but it's an option just in case.</p>-->
|
||
|
|
|
||
|
|
<p><b>Video settings</b> - Select to access the following controls:</p>
|
||
|
|
|
||
|
|
<p><b>Video resolution</b> - Select the resolution of videos taken by the camera.</p>
|
||
|
|
|
||
|
|
<p><b>Enable digital video stabilization</b> - Video stabilization reduces the shaking due to the motion of the camera in
|
||
|
|
both the preview and in recorded videos. This enables a digital method in the camera driver, and may be unnecessary if
|
||
|
|
your device supports optical image stabilization (OIS).</p>
|
||
|
|
|
||
|
|
<p><b>Video format</b> - Allows choice of various video file formats and codecs. Please test before using, as some may
|
||
|
|
not work properly on all devices! Also note:</p><ul>
|
||
|
|
<li>WebM does not support recording audio (at the time of writing, it seems encoding in Vorbis audio format is
|
||
|
|
<a href="https://developer.android.com/guide/topics/media/media-formats#audio-formats">not supported</a> on
|
||
|
|
Android).</li>
|
||
|
|
<li>WebM does not support storing location data ("Store location data" option).</li>
|
||
|
|
<li>If using 3GPP, then restarting video when hitting maximum filesize will not be seamless (even on Android 8).</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Video picture profiles</b> - Enables different color profiles for recording video. Only available if Camera2
|
||
|
|
API is used, and only supported on some devices. Additional notes:</p><ul>
|
||
|
|
<li>The various "log" profiles enable a "flat" color profile, and are intended to create videos
|
||
|
|
for further editing in post production.</li>
|
||
|
|
<li>Note that it may be necessary to increase the video bitrate when shooting with a "log" profile
|
||
|
|
or with high custom gamma.</li>
|
||
|
|
<li>When "Gamma" is selected, you can specify the gamma value used with the next option "Video gamma value".</li>
|
||
|
|
<li>This feature is somewhat experimental, please test if it fits your need before shooting your masterpiece!</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Max duration of video</b> - This option can be used to set a maximum duration of the video. If set, video recording
|
||
|
|
will stop after the specified time (unless already stopped earlier).</p>
|
||
|
|
|
||
|
|
<p><b>Restart video after max duration</b> - If a max duration has been set (see above), this option can be used to make
|
||
|
|
the video automatically stop and restart the specified number of times. So this can be used to take a video for a long
|
||
|
|
period, broken up into multiple video files. If a max duration has not been set, then this option has no effect.</p>
|
||
|
|
|
||
|
|
<p><b>Maximum file size of video</b> - This allows to set a maximum file size for videos. Note that many Android devices
|
||
|
|
set a maximum file size (typically around 2GB or 4GB), and there is no way Open Camera can work around such a limitation (and
|
||
|
|
using exFAT doesn't get round it). This option allows you to set a smaller maximum file size - note that it can only
|
||
|
|
be used to reduce the device's maximum file size (so if a device has a 2GB limit, you can't increase it by setting this option to
|
||
|
|
a larger value). Note that the value is approximate - typically
|
||
|
|
the resultant videos may be slightly smaller. Note that if you using this option together
|
||
|
|
with "Max duration of video", then - if "Restart on maximum file size" is enabled - hitting the maximum file size will cause a
|
||
|
|
restart that doesn't reset the max duration timer, nor does it count as one of the number of restarts. E.g., if you requested a
|
||
|
|
maximum duration of 30m, with 1 restart, but the video hits the maximum file size after 20m, rather than getting two times 30m
|
||
|
|
videos, you'd get four videos, of lengths 20m, 10m, 20m, 10m (i.e., the 30m videos are split at the maximum file sizes). If
|
||
|
|
"Restart on maximum file size" is disabled, then hitting the maximum file size will always cause the video to end without
|
||
|
|
restarting, even if you've set "Restart video after max duration".</p>
|
||
|
|
|
||
|
|
<p><b>Restart on maximum file size</b> - Whether to automatically restart if the maximum file size is met. As noted above, almost all
|
||
|
|
Android devices have a maximum file size for videos, even if you don't explicitly set one. So it's advisable to keep this option to true,
|
||
|
|
so that Open Camera will restart as soon as possible if you're recording video, and hit this limit. Note that on devices that
|
||
|
|
are not running Android 8 or later, there will still be a loss of a few seconds while the video stops and restarts. On Android 8
|
||
|
|
or later, the resume should be seamless (unless using 3GPP video file format).</p>
|
||
|
|
|
||
|
|
<p><b>Record audio</b> - Whether to record audio when recording a video.</p>
|
||
|
|
|
||
|
|
<p><b>Audio source</b> - Select the audio source for recording video. The effect of this depends on your device -
|
||
|
|
if it supports an external microphone, you may be able to use this by selecting "External mic". The other options may
|
||
|
|
provide different settings affecting the resultant audio (e.g., automatic gain control), though this behaviour is
|
||
|
|
device specific. These options are just controls for the Android MediaRecorder API, and so the exact behaviour is
|
||
|
|
up to the device.</p>
|
||
|
|
|
||
|
|
<p><b>Audio channels</b> - If recording audio with video, this option allows you to specify mono or stereo recording.
|
||
|
|
Note that most devices do not support stereo recording. Even for devices that do support this, you may need to modify
|
||
|
|
the "Audio source" option to another value for this to work.</p>
|
||
|
|
|
||
|
|
<p><b>Lock screen when recording video</b> - If enabled, the GUI will be locked when recording video (i.e., the GUI
|
||
|
|
won't respond to touch presses). You can use this to prevent accidental presses that might change settings or stop
|
||
|
|
recording. To unlock the GUI, swipe the screen (in any direction). Note that this won't prevent the video being
|
||
|
|
stopped if you press your device's Home, Recent Apps or Power button (it is not possible for apps to override the
|
||
|
|
behaviour of these buttons).</p>
|
||
|
|
|
||
|
|
<p><b>Video subtitles</b> - This option is analogous to the "Stamp photos" option, but rather than embedding text into
|
||
|
|
the video itself, it stores the text in a separate subtitles
|
||
|
|
(<a href="https://www.matroska.org/technical/subtitles.html#srt-subtitles">".SRT"</a>) file. Most decent video players should support
|
||
|
|
SRT files, and use them to display the information as subtitles. The subtitles will record the date and time. If "Store location data" is enabled (see
|
||
|
|
"Location settings" below), then the current location latitude and longitude coordinates will also be recorded (if the location is
|
||
|
|
known). Similarly for "Store compass direction". Note that you can control the formatting style for date, time and location using
|
||
|
|
the options under the "Photo settings" menu (Datestamp format, Timestamp format, GPS stamp format, Distance unit).</p>
|
||
|
|
<ul>
|
||
|
|
<li>Note that on Android 10, using this option means the ".SRT" files will show in most gallery apps as separate unplayable video
|
||
|
|
files. A workaround is to enable Settings/More camera controls/"Storage Access Framework".</li>
|
||
|
|
<li>On Android 11+, this option is only available if Settings/More camera controls/"Storage Access Framework" is
|
||
|
|
enabled. This is due to changes in Android 11 which affect how applications are able to save files.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Video bitrate (approx)</b> - If set to a value other than "default", the default video bitrate is overridden. Higher values mean better
|
||
|
|
quality video, but the files take up more disk space. Note that some values may be unsupported by your device, and may
|
||
|
|
cause the recording to fail - in some cases, this can cause problems with the camera that require a reboot to fix. So
|
||
|
|
please test before using. Also note that the bitrate setting is approximate - the resultant video file will typically be slightly different
|
||
|
|
to that requested.</p>
|
||
|
|
|
||
|
|
<p><b>Video frame rate (approx)</b> - If set to a value other than "default", the camera will try to match this frame
|
||
|
|
rate.</p>
|
||
|
|
<ul>
|
||
|
|
<li>This is very approximate, as frame rate depends on many factors such as your device and lighting
|
||
|
|
conditions, and this is only a "recommendation" to the camera driver, so there is no guarantee that the
|
||
|
|
resultant video's frame rate will match with the requested value.</li>
|
||
|
|
<li>Some frame rate values may be unsupported by your device, and cause the recording to fail, so please test before
|
||
|
|
using.</li>
|
||
|
|
<li>Even if video recording is successful, if achieving a specific FPS is desired, please check the resultant video's
|
||
|
|
frame rate rather than assuming that it was achieved.</li>
|
||
|
|
<li>For best results (especially for 120fps or higher), please set Settings/"Camera API" to "Camera2 API".</li>
|
||
|
|
<li>This setting is ignored in slow motion mode, where instead Open Camera will choose an appropriate high speed frame
|
||
|
|
rate.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Force 4K UHD video (may not work on all devices)</b> - Enable recording in 4K UHD (3840x2160) on the back camera (if ticked,
|
||
|
|
this overrides the setting in "Video resolution"). This is provided for some phones that don't properly expose their 4K video resolution to 3rd party camera apps
|
||
|
|
(and so 4K resolution doesn't show in the Video resolution option above).
|
||
|
|
It turns out that some such devices can be made to record in 4K resolution if it's requested, but on other devices this won't work.
|
||
|
|
If you enable this on a device that doesn't support it, you may either get an error
|
||
|
|
message when you try to record, or it may succeed but create a video where the resolution isn't 4K, or may even result in a crash! So
|
||
|
|
please test this out first. I've tested this successfully on a Samsung Galaxy S5 and Note 3, but even there it only works on some
|
||
|
|
variants of those devices. If this doesn't work, it isn't a bug in Open Camera, it's because your device doesn't support 4K recording
|
||
|
|
for third party camera apps. (If this option doesn't show up at all, it's either because your device already lists 4K in the Video
|
||
|
|
resolutions options above, or because Open Camera thinks this is a device that probably doesn't support 4K video.)</p>
|
||
|
|
|
||
|
|
<p><b>Critical battery check</b> - If a device runs out of power while recording video, in theory the video should safely stop in time.
|
||
|
|
However in some cases this doesn't happen in time (if the video file is large, post-processing may still be occurring when the device
|
||
|
|
switches off), causing the entire video file to be corrupted! To reduce this risk, Open Camera will stop video recording when the
|
||
|
|
battery level is low (3%), but before the device is about to shut off. If for some reason you don't want this behaviour, you can
|
||
|
|
switch this option off.</p>
|
||
|
|
|
||
|
|
<p><b>Flash while recording video</b> - If enabled, the camera flash will flash every second while recording video. This
|
||
|
|
isn't something most people will need, but it can be useful if the phone is being operated remotely, as a signal that the
|
||
|
|
video is still recording.</p>
|
||
|
|
|
||
|
|
<p><b>Location settings</b> - Select to access the following controls:</p>
|
||
|
|
|
||
|
|
<p><a name="store_location_data"><b>Store location data (Geotagging)</b></a> - If selected, then photos will be tagged with the current
|
||
|
|
location. Location data will also be stored in videos (though only for devices that record in MPEG4 or
|
||
|
|
3GPP formats).</p>
|
||
|
|
|
||
|
|
<p><b>Store compass direction</b> - If selected, then photos will be tagged with the compass direction.
|
||
|
|
Only supported for JPEG formats. Not supported for RAW photos (DNG format) or videos.</p>
|
||
|
|
|
||
|
|
<p><b>Store yaw, pitch and roll</b> - If selected, then photos will be tagged with the device's yaw, pitch and roll.
|
||
|
|
Note that Exif data does not have direct support for this, instead it will be written as a string in the Exif data's
|
||
|
|
User Comment for the image. Only supported for JPEG formats. Not supported for RAW photos (DNG format) or videos.</p>
|
||
|
|
|
||
|
|
<p><b>Require location data</b> - If "Store location data" is enabled, then also enabling this option means that
|
||
|
|
photos and videos can only be taken if location data is present (this can be useful if you need pictures/videos to
|
||
|
|
have location data in them).</p>
|
||
|
|
|
||
|
|
<p><b>Processing settings</b> - Select to access the following controls:</p>
|
||
|
|
|
||
|
|
<p><b>Anti-banding</b> - Some kinds of lighting, such as some fluorescent lights, flicker at the rate of the power supply
|
||
|
|
frequency (60Hz or 50Hz, depending on country). While this is typically not noticeable to a person, it can be visible to
|
||
|
|
a camera. If a camera sets its exposure time to the wrong value, the flicker may become visible in the viewfinder as flicker
|
||
|
|
or in a final captured image, as a set of variable-brightness bands across the image. Therefore, the auto-exposure routines
|
||
|
|
of the camera include antibanding routines that ensure that the chosen exposure value will not cause such banding. The choice
|
||
|
|
of exposure time depends on the rate of flicker, which the camera can detect automatically, or the expected rate can be
|
||
|
|
specified by using this option.</p>
|
||
|
|
|
||
|
|
<p><b>Edge mode algorithm</b> - Only available if Camera2 API is used. Allows control over the algorithm used by the camera
|
||
|
|
driver for applying edge enhancement. Edge enhancement improves sharpness and details in the captured image, though on
|
||
|
|
some devices you may prefer to turn it off if it introduces undesirable effects. Note that this setting is ignored in

<p><b>Camera API</b> - If set to "Camera2 API", this enables support for the Camera2 API that was introduced
|
||
|
|
in Android 5. Changing this setting will cause Open Camera to restart. Camera2 API enables more advanced features
|
||
|
|
(including manual ISO/exposure, manual focus, HDR, exposure bracketing).
|
||
|
|
Note that not all Android 5+ devices have full support for the Camera2 API (Open Camera will only show this
|
||
|
|
option if at least one camera reports either "LIMITED" or "FULL" support for the API; "LEGACY" only devices are not supported).
|
||
|
|
Also note that even if devices support Camera2 API, some
|
||
|
|
devices have poor support.
|
||
|
|
These are not necessarily bugs in Open Camera, but problems with manufacturer support for Camera2 API. If you have
|
||
|
|
problems with flash behaviour, try the "Use alternative flash method" setting under "Photo Settings".

<p><a name="faq"><b>Frequently Asked Questions</b></a></p>
|
||
|
|
|
||
|
|
<p><b>How can I save to my external SD card?</b> - This depends on your Android version:</p>
|
||
|
|
<ul>
|
||
|
|
<li><b>Android 5.0 onwards</b> - enable Settings/More camera controls/"Storage Access Framework", and this should allow you
|
||
|
|
to save to external SD cards. If when choosing a folder, you only see "Recent", you may need to click on the
|
||
|
|
three dots at the top right to open the menu, to enable showing the drives (e.g., "Show internal storage").</li>
|
||
|
|
<li><b>Android 6.0 onwards</b> - From Android 6, some devices support "Adoptable Storage" allowing you to
|
||
|
|
select to use
|
||
|
|
an SD card as internal storage. Note that not all devices support this, even if running Android 6 or later. If your device
|
||
|
|
doesn't support this, or you want to instead use an SD card as "portable storage", you'll have to use
|
||
|
|
the Storage Access Framework method as with Android 5.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>Can you implement disabling shutter sound for my phone?</b> -
|
||
|
|
If Open Camera shows the option Settings/"Camera API", then changing to "Camera2 API" means you'll be able to disable
|
||
|
|
shutter sounds under "Settings/More camera controls...".
|
||
|
|
When not using Camera2 API, if the option "Shutter sound" under "More camera controls..." isn't shown,
|
||
|
|
then it's not available. There
|
||
|
|
are possible workarounds for some of these devices (which is why some third party camera applications
|
||
|
|
may be able to silence the shutter), though the issue is these don't work on all devices, and tend
|
||
|
|
to use methods that Google now discourage. The fault is with the device for not supporting
|
||
|
|
standard method for cameras to disable the shutter sound on Android. In particular, if under Settings/About
|
||
|
|
you see that "Can disable shutter sound?" says No, it means the device's camera API is telling 3rd
|
||
|
|
party camera apps that shutter sound can't be disabled (so either it can't do it, or the API is lying
|
||
|
|
- either way, this should be reported to your manufacturer).</p>
|
||
|
|
|
||
|
|
<p><b>Photos or videos fail to save!</b> - Firstly, if you're trying to save to an
|
||
|
|
external SD card, see "How can I save to my external SD card?" above. Otherwise:</p>
|
||
|
|
<ul>
|
||
|
|
<li>If Settings/More camera controls/"Storage Access Framework" is enabled,
|
||
|
|
in some cases the permission may be lost, try rechoosing the save location (from
|
||
|
|
Settings/More camera controls/"Save location").</li>
|
||
|
|
<li>If not using Storage Access Framework, but you have changed the save location,
|
||
|
|
it may be you've chosen somewhere where applications don't have permission to save
|
||
|
|
files.</li>
|
||
|
|
<li>Or sometimes simply restarting the devices fixes such problems.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>I switched to a new phone, and now something doesn't work!</b> - Google's auto-backup will
|
||
|
|
typically transfer settings to a new phone, but this may mean a camera-specific setting is no
|
||
|
|
longer relevant. In particular, if you set a non-default save location, it may be that the path is
|
||
|
|
not valid on the new device, or if using Settings/More camera controls/"Storage Access Framework",
|
||
|
|
you may need to rechoose the save location (from Settings/More camera controls/"Save location") to
|
||
|
|
grant permission to the new device. You can use Settings/Settings manager/"Reset settings" to reset
|
||
|
|
Open Camera to its original state, to rule out any issues from an Android backup from another
|
||
|
|
device.</p>
|
||
|
|
|
||
|
|
<p><b>My pictures are being rotated/cropped!</b> - This likely means the <a href="#auto_stabilise">auto-level</a>
|
||
|
|
option is on. (If they're being rotated even when the phone is held level, it may mean the accelerometer sensor on your
|
||
|
|
device isn't calibrated.) It's off by default, but you may have accidentally switched it on. To turn off, go to the "popup" menu
|
||
|
|
and untick Auto-level.</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't Open Camera support dual / multiple cameras?</b> - Open Camera supports cameras
|
||
|
|
that are made available to third party applications, although you may need to set Settings/"Camera API"
|
||
|
|
to "Camera2 API". When using Camera2 API, many devices expose multiple cameras via the zoom - zooming out to less
|
||
|
|
than 1x switches to the ultra-wide camera, zooming in automatically switches to the telephoto when
|
||
|
|
required. On other devices, the cameras can be manually switched by using the
|
||
|
|
<img src="baseline_add_a_photo_white_48.png" alt="Switch multi-camera icon" width="16" height="16">switch multi-camera icon.
|
||
|
|
Note that some devices don't allow third party applications to use their extra cameras, either
|
||
|
|
via zoom or by explicitly switching to the camera. In such cases Open Camera cannot access them.</p>
|
||
|
|
|
||
|
|
<p><b>But another third party camera app can access the extra cameras on my device, why can't Open Camera?</b> -
|
||
|
|
On some devices, it may be possible to access the camera by ignoring what the device claims, and trying to
|
||
|
|
access the camera IDs anyway. This is a hack - on other devices, this will lead to buggy behaviour where
|
||
|
|
cameras are exposed that hang or otherwise don't work. The problem here is that the device does not
|
||
|
|
support exposing the cameras to third party camera applications via the Android camera API.</p>
|
||
|
|
|
||
|
|
<p><b>But can't you use the hacky method to access the extra cameras anyway?</b> - Put it this way:
|
||
|
|
you paid hundreds of pounds for a device from a large company with lots of resources, but you
|
||
|
|
want the free application to do the extra work to workaround the device's limitation, even when it's a hacky
|
||
|
|
method? Sometimes I do implement workarounds for device limitations - but it is risky to do so here.</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't Open Camera support the maximum video resolution on my device?</b> - If you
|
||
|
|
are using Camera2 API, make sure that you're not in slow motion mode (see "Speed" under
|
||
|
|
the popup menu), and you don't have a non-default frame rate set (under Settings/Video settings). If
|
||
|
|
a high speed frame rate is in use, then this usually limits the maximum video resolution. If this
|
||
|
|
isn't the case, then it may be that the device isn't exposing the highest video resolution to third
|
||
|
|
party applications (e.g., this is common for 4K/UHD video resolutions on older devices, especially
|
||
|
|
if Camera2 API isn't enabled).</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't the FPS/bitrate setting for video work?</b> - These settings only give "recommendations" to the
|
||
|
|
camera, and there is no guarantee that they will be met. For best chance of success, try setting Settings/"Camera API" to "Camera2 API".</p>
|
||

<p><b>But my camera can do 60/120FPS, so why can't Open Camera?</b> - High frame rates often are achieved only by the
|
||
|
|
"stock" camera app (or "mods" of it) because these are written for a specific device and don't have to go through
|
||
|
|
the standard Android camera API. Some devices do now support high speed frame rates when Camera2 API is enabled.</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't Open Camera show 23MP resolution on my Sony Xperia, only 8MP?</b> - This was a problem on older devices
|
||
|
|
and/or with the old Camera API because of Sony not making this available to third party camera applications. On newer Sony
|
||
|
|
devices, this should become available if you set Settings/"Camera API" to "Camera2 API".</p>
|
||
|
|
|
||
|
|
<p><b>Why does the resolution of my photos not match the specified camera resolution?</b> - This happens if
|
||
|
|
<a href="#auto_stabilise">auto-level</a> is enabled. The image is rotated to be level, which means the
|
||
|
|
resolution (and aspect-ratio) will change.</p>
|
||
|
|
|
||
|
|
<p><b>Why can't I change the ISO?</b> - Even if your device supports ISO, this may not be made available through the
|
||
|
|
standard Android API for 3rd party camera apps to use.</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't touch to focus work?</b> - Touching the screen should allow you to choose a particular region to focus
|
||
|
|
on. If this doesn't work:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Check the focus mode (under the popup menu), for best results you usually want
|
||
|
|
<img src="focus_mode_continuous_picture.png" alt="Continuous focus icon" width="16" height="16">Continuous or
|
||
|
|
<img src="focus_mode_auto.png" alt="Continuous focus icon" width="16" height="16">Auto focus modes.</li>
|
||
|
|
<li>Check that <a href="#face_detection">Settings/"Face detection"</a> is disabled (focus regions aren't possible in face detection mode).</li>
|
||
|
|
<li>Some devices or cameras (especially front cameras) don't support touch to focus.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p><b>I get "FAILED TO OPEN CAMERA"</b> - In some cases this is fixed by restarting
|
||
|
|
Open Camera, or otherwise make sure nothing else is using the camera (including the
|
||
|
|
torch being enabled). In some cases a phone gets into a state where the camera can't
|
||
|
|
be opened, which is fixed by rebooting. If it persists even after restarting your
|
||
|
|
device, try other camera applications in case the camera is faulty.</p>
|
||
|
|
|
||
|
|
<p><b>Why has Open Camera stopped working properly?</b> - If something stops working in Open Camera
|
||
|
|
first try a reboot of your device. If that doesn't resolve the problem, try resetting
|
||
|
|
the settings to the defaults (under Settings/Settings manager/"Reset settings"), or try reinstalling
|
||
|
|
the app (or go to your device's App Settings and select "Clear data" for Open Camera) to
|
||
|
|
reset it to its initial conditions. Obviously ideally this shouldn't happen, but can be a way of
|
||
|
|
working around any unresolved bugs that appear. If something stops working in an upgrade to a new
|
||
|
|
version of Open Camera, and the problem isn't resolved by a reinstall/Clear data, please let me
|
||
|
|
know, but in the meantime you can install the older versions from
|
||

|
<p><b>Why doesn't the preview display match the resultant photo/video? One of them is cropped.</b> - Firstly, make
|
||
|
|
sure that Settings/Camera preview/Preview size is set to "Match photo size (WYSIWYG)". However if that doesn't fix
|
||
|
|
the problem, this is a limitation on some devices and photo/video resolutions (it happens if the device doesn't offer
|
||
|
|
a "preview" with the same aspect ratio as the chosen photo/video resolution). A workaround may be to try a different
|
||
|
|
resolution for photos and/or videos.</p>
|
||
|
|
|
||
|
|
<p><b>Why isn't Open Camera available in my language?</b> - I can only speak English I'm afraid. Please contact me
|
||
|
|
if you're willing to do a translation (this doesn't require any knowledge of Android programming, it's just a case
|
||
|
|
of translating a set of strings in a text file).</p>
|
||
|
|
|
||
|
|
<p><b>Why is the non-English translation of my language incomplete?</b> - Scene modes and color effects aren't
|
||
|
|
currently translated, as these are just strings returned by the camera. Also note that even if I get someone to
|
||
|
|
translate Open Camera, when I later add new features/options, this may require additional strings which aren't
|
||
|
|
translated. I don't have a team of paid translators, so it's not always possible to keep translations up to date :)</p>
|
||
|
|
|
||
|
|
<p><b>The non-English translation is wrong!</b> - I can only speak English, and am dependent on other people to
|
||
|
|
offer translations. If you think a particular translation is inaccurate, please let me know.</p>
|
||
|
|
|
||
|
|
<p><b>Why is the screen forced to maximum brightness?</b> - If you don't like this feature, you can switch it off
|
||
|
|
by going to Settings/On screen GUI/Force maximum brightness.</p>
|
||
|
|
|
||
|
|
<p><b>Does Open Camera support selfie sticks / bluetooth remotes?</b> - Open Camera has support for some selfie sticks
|
||
|
|
though different sticks work in different ways, so it's hard to guarantee this. Sticks and bluetooth remote controls
|
||
|
|
which work by triggering a volume key press should work (and the behaviour can be configured by
|
||
|
|
Settings/More camera controls/"Volume keys").</p>
|
||
|
|
|
||
|
|
<p><b>Why is auto-level slow?</b> - This feature requires doing a decompress of the JPEG data, followed by a
|
||
|
|
rotation of a multi-megapixel image, then recompressing, which typically results in a short pause on most devices.
|
||
|
|
And as devices get faster CPUs, they typically come with cameras with even bigger megapixels! This is why I've made
|
||
|
|
it optional (and you can set the volume control to quickly switch it on and off if you like).</p>
|
||
|
|
|
||
|
|
<p><b>Why is auto-level for photos only?</b> - Doing auto-level for video is a <i>massively</i> harder
|
||
|
|
problem. This wouldn't be possible in real-time - rotating images causes a noticeable pause as it is, imagine
|
||
|
|
having to do that for every frame. Also the rotation angle wouldn't be constant, so it's a much harder problem
|
||
|
|
figuring out what the correct result should actually be.</p>
|
||
|
|
|
||
|
|
<p><b>Can I launch a different gallery app when I press the gallery icon? Why doesn't Open Camera
|
||
|
|
have its own gallery app?</b> - If you have more than one Gallery app on your device, you should be
|
||
|
|
given the choice which to use when you press the gallery icon. If one app is already set up as the
|
||
|
|
default and you want to change it, then go to the App Settings for that app, and under
|
||
|
|
"Launch by default" (or something like that) it will list if it is set as the defaults for any
|
||
|
|
actions, with an option to clear them. There are plenty of gallery apps for Android, and it seems
|
||
|
|
better for users to have this choice, rather than Open Camera having its own custom gallery.</p>
|
||
|
|
|
||
|
|
<p><b>Clicking on the thumbnail icon only shows the photo briefly?</b> - This can happen if you've changed the save location
|
||
|
|
for photos/videos to one that is not typical (e.g., not inside DCIM/ ). Some gallery applications will not show a photo in
|
||
|
|
such cases.</p>
|
||
|
|
|
||
|
|
<p><b>Why does Open Camera have ads?</b> - Open Camera does not have ads in the application (there may be ads on the online
|
||
|
|
webpage you're reading now, but not in the app). There are however some clones on Google Play with ads inserted.
|
||
|
|
Please ensure that you've downloaded from one of the places listed above
|
||
|
|
on this page.</p>
|
||
|
|
|
||
|
|
<p><b>Does Open Camera support features like manual controls for exposure/ISO/focus, and RAW?</b> -
|
||
|
|
Set Settings/"Camera API" to "Camera2 API" for such features (if the option isn't there, it's not supported on your device).
|
||
|
|
This is turned off by default as some <a href="devices.html">devices</a> have poor behaviour.</p>
|
||
|
|
|
||
|
|
<p><b>Why can't I select the Camera2 API?</b> - Some devices only have
|
||
|
|
"legacy" Camera2 support, which means it isn't any better than the original Camera API. Open Camera doesn't support
|
||
|
|
enabling Camera2 on such devices.</p>
|
||
|
|
|
||
|
|
<p><b>Does Open Camera support HDR+, or use the Pixel's Visual Core?</b> If you have a Google Pixel with Pixel Visual Core, then Open Camera
|
||
|
|
should be using HDR+ when the following settings are set: Photo Mode Standard, flash off (or auto if the flash doesn't fire),
|
||
|
|
white balance auto, color effect none, no exposure compensation, no manual ISO/exposure, no RAW. HDR+ should be
|
||
|
|
supported in both old and Camera2 API. See
|
||
|
|
<a href="https://sourceforge.net/p/opencamera/discussion/general/thread/61950751/">this thread</a> for more discussion.
|
||
|
|
Note that some Google Pixels (e.g., 3a) do not have a Pixel Visual Core chip, and may not support HDR+ in third party
|
||
|
|
camera applications (see <a href="https://sourceforge.net/p/opencamera/tickets/592/">this thread</a>).</p>
|
||
|
|
|
||
|
|
<p><b>Why isn't Panorama supported on my device?</b> - To support panorama in Open Camera, this requires
|
||
|
|
a gyroscope and compass, and at least 256MB of "large heap" memory (note, this isn't the same as the device's RAM).
|
||
|
|
Bear in mind that even if your device supports panorama, with Open Camera I have to support thousands of Android devices,
|
||
|
|
and I don't have the luxury of targetting functionality towards one particular device.</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't Open Camera's HDR images look like other HDR camera apps?</b> - There are a great many different ways
|
||
|
|
of applying a HDR algorithm, some may do better or worse in different circumstances; some may look more or less pleasing
|
||
|
|
depending on what you are after. Also note that some camera apps use "HDR" to mean "apply a whacky-looking filter".
|
||
|
|
Whilst HDR filters can be used to apply a rather unreal or vivid image, for now Open Camera's HDR is more geared towards
|
||
|
|
capturing the range of exposures.</p>
|
||
|
|
|
||
|
|
<p><b>Why doesn't Open Camera's HDR photos look as good as other HDR photos I see?</b> - Firstly, see the previous question.
|
||
|
|
Beyond that, many HDR photos you see on the Internet may have been manually processed in HDR software that allows the
|
||
|
|
user to tweak settings for optimal results for a given image. Such photos may have had additional processing done. Open
|
||
|
|
Camera's HDR algorithm tries to get the best results for most purposes automatically, but isn't going to beat manual
|
||
|
|
editing.</p>
|
||
|
|
|
||
|
|
<p><b>I ran out of space while recording video, and the video is corrupted, how can I get it back?</b> - Firstly, this sadly
|
||
|
|
isn't an Open Camera bug - it's an issue that the video recording API doesn't stop or report an error when storage
|
||
|
|
runs out. As a workaround, Open Camera does try to stop videos when storage space is low (although note this workaround
|
||
|
|
may not be feasible in some cases if saving to non-default locations). In order to recover a file, you can try
|
||
|
|
"MP4Fix Video Repair Tool" by Smamolot (com.smamolot.mp4fix) (not affiliated with me or Open Camera!).</p>
|
||
|
|
|
||
|
|
<p><b>My device ran out of power while recording video, and the video is corrupt! How can I get it back?</b> - This can happen if
|
||
|
|
the device is very slow at processing the video file after stopping, and this doesn't finishing when the device powers off. Open
|
||
|
|
Camera will stop the video in advance of the device shutting down to help reduce this risk (see "Critical battery check" option),
|
||
|
|
but if this still happens, the best hope is to try MP4Fix, see the previous question. Note that if this happens, it isn't an
|
||
|
|
Open Camera bug - it's a problem that will happen on any device where the device shuts off before the video can be processed.</p>
|
||
|
|
|
||
|
|
<p><b>Does Open Camera support external USB cameras?</b> - Unfortunately Open Camera does not support USB cameras. These don't
|
||
|
|
seem to use the standard Android camera APIs, and it would be a lot of work to add support for these.</p>
|
||
|
|
|
||
|
|
<p><b>I don't like the UI!</b> - The UI for Open Camera has improved significantly over the versions (both in terms
|
||
|
|
of having a consistent look, and the operation), so this criticism seems to have gone down, but there's always room
|
||
|
|
for improvement! However, in order for me to improve, please be specific: comments like this could mean all sorts of
|
||
|
|
things, such as the style of the icons, the arrangement of the icons, wanting more things on the main screen, wanting
|
||
|
|
less things on the main screen, preferring swipes to icons, wanting it easier to change certain options, or even that
|
||
|
|
some devices may have a bug that I'm not aware of. Also bear in mind that some preferences may be a matter of opinion
|
||
|
|
and it's not possible to get an app that satisfies everyone (e.g., some camera apps hide everything behind popup menus
|
||
|
|
that you swipe to enable; others have as much on screen as possible - I try to achieve a balance in Open Camera).</p>
|
||
|
|
|
||
|
|
<p><b>Why is the UI cluttered?</b> - Under Settings/"On screen GUI", there are options to disable various controls and
|
||
|
|
so on from the main view.</p>
