Photo Mate R2, a Raw converter app for Android that we covered in a comprehensive review almost exactly a year ago, has received a major update putting a new Library function at its core. The feature is still in beta but appears to be working pretty reliably. It allows you to arrange all the images on a device, including EXIF-data and XMP-files in a library and offers a wide range of multi-level sorting options. You can sort by date, ISO, aperture, rating and other criteria and create combinations from all of those.

The update also includes a new "High Quality Color Noise" option in the editing section, a new keyword-view and a range of bug fixes. As before, Photo Mate R2 offers a wide range of raw editing options including digital exposure compensation, white balance, fill-light and highlight recovery. You can adjust the sharpening amount and radius and control both luminance and color noise reduction. In the lens section you can correct distortion, vignetting and chromatic aberrations among other lens flaws. If you only want to work on a specific area on an image gradient, circular, brush and lasso selection tools are at your disposal. There are also functions for batch processing, keywording and image rating.

The video below gives you a more detailed description of the new Library feature. If you think Photo Mate R2 could be a useful addition to your set of photographic tools you can download the app for $9.99 from the Google Play Store. It is compatible with Android 4.0 and newer versions. 2GB of RAM and a dual-core processor are recommended.
