Popdisplay
There seems to be a major flaw with the exposure. When you apply "fix" I get horizontal banding across the image. If I turn the exposure off entirely, the banding goes away. Unfortunately, exposure is a very important component in image correction.
Fix this problem and I will review the app again. Until the exposure control is fixed, the app is useless.
