I just shot a few shots with my new/used P25+ and I noticed there were light leaks in my bellows (I am shooting it attached to a horseman view camera with a 210mm caltar lens. When opening the files on my computer (in PS CS3) I found that there were maze shaped patterns on the image, especially where the light leak occurred. I had seen this before with one of sony's dslrs but never on a digital back. When opening the same file in Capture One Pro it seems the file's mosaic pattern either was
a) not there anymore
b) was smoothed over/affected by slight posterization.
Does anyone know what causes this/where I could find out more about the pattern, what causes it, how to remedy?
