<p>Simply point, and press the blue camera icon <img src="take_photo.png" alt="Take Photo icon" width="32" height="32"> to take a photo.

<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). To zoom, use the slider next to the take photo button, or do a multi-touch "pinch"

</ul>

<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 will switch to video mode. The photo and video icons will then swap: click the larger video icon to

    start/stop video recording, and click the smaller photo icon to switch back to photo mode.</p>

    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

    <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>In continuous focus mode, a white circle shows to indicate that the camera is focusing. When touching to focus, or in

    autofocus mode, a white square is shown (depending on the focus mode), which turns green to indicate that the auto-focus was

    successful, or red if it was not.</p>

photos look right whether you hold the device in "portrait" or "landscape" mode. But Open Camera has the option to rotate the

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

        that expose multiple cameras).
