Is there an app to use PNG for the FFC? This is semi-related to a previous question and I have a new theory I want to test. I am looking for a camera app that will store it's images in PNG format (what screenshots are stored in) instead of the lossy jpeg.

Camera FV-5 is the only app I could find that mentions PNG support, but it does not support the FFC.
JPEG with 100% compression quality is not lossless but maybe the picture quality will be good enough for you, here are two apps I know which has the ability to set the compression quality to 100%:


Snap Camera HDR (JPEG Quality: Best = 100% according to the developers website), trial here
Camera MX
