Note: using iPad2 running iOS6
Version 2.5: Still crashes while trying to load imges over 8mp, very stable with images below 7mp. Unstable between 7 and 8mp. Does produce nice results. Includes a single slider to adjust level of adjustment. This really needs to be fixed. For a "one trick pony" to stumble out of the gate is a real disappointment. I refuse to downsample all my images and lose the resolution just to use this app. There are other options available that don't step on my images.
Additionally, the "Compare" funtion that splits the screen doesn't go off without Reset, and with the splitscreen displayed showing before and after, if you hit Save, it saves the image with the split screen! What? Why?
Version 2: Crashes trying to load images over 8mp. The app does save at original resolutions up to 8mp, obviously I don't know beyond that since the app will not load anything higher without crashing.
Version 1.1: This app does a nice job of correcting color casts, however like dozens of other photo apps, it arbitrarily reduces the original image size, reducing the resolution of the saved image. There are no size options and the app, nor the description above, mentions this "feature".
Fix it so it saves the original resolution, especially hi-res 12mp images, and you get 5 stars, until then, it gets deleted as it is worthless to me if it can't load my images.
