Open Camera is a highly versatile and completely free camera app designed to enhance your photography experience on Android devices. With its robust set of features, it caters to both casual photographers and those who demand more control over their camera settings.

One of the standout features is the auto-level option, which ensures your photos are perfectly aligned, regardless of the angle at which you're shooting. This feature is particularly useful for maintaining the integrity of your shots, making them look professional and well-composed.

Open Camera unlocks the full potential of your device's camera with support for scene modes, color effects, white balance adjustments, ISO settings, exposure compensation and lock, and even a "screen flash" for selfies. It also supports HD video recording, allowing you to capture high-quality footage with ease.

For those who enjoy remote photography, Open Camera offers a timer with an optional voice countdown, an auto-repeat mode with configurable delays, and the unique ability to take a photo remotely by making a noise. Additionally, the app allows for customizable volume key functions and a user-friendly interface that can be tailored to your preferences.

Photography enthusiasts will appreciate the upside-down preview option, which is perfect for use with attachable lenses, and the ability to overlay grids and crop guides for precise composition. The app also supports optional GPS location tagging (geotagging) for both photos and videos, including compass direction information for photos, which adds valuable metadata to your captures.

Open Camera offers extensive post-capture customization, allowing you to apply date and timestamps, location coordinates, and custom text to your photos. You can even store date/time and location as video subtitles in .SRT format. For privacy-conscious users, there's an option to remove device exif metadata from photos.

The app also supports panorama shots, including for the front camera, and advanced features like HDR with auto-alignment and ghost removal, as well as Exposure Bracketing. Open Camera leverages the Camera2 API for manual controls, focus assist, burst mode, RAW (DNG) file support, camera vendor extensions, slow motion video, and log profile video.

For those looking to refine their photography further, Open Camera includes noise reduction (including a low light night mode), dynamic range optimization modes, and options for on-screen histogram, zebra stripes, and focus peaking. Focus bracketing mode is also available for those who want to experiment with depth of field.

What sets Open Camera apart is its commitment to being completely free, with no third-party ads within the app itself. It's also open-source, allowing developers to contribute to and improve the app. However, it's important to note that some features may not be available on all devices due to hardware or camera limitations and the Android version in use.
