Hi, I've recently moved to shooting RAW. I am using a canon 1d mkII N and CS2 to convert the files. However I am getting a lot of noise in the backgrounds of most of the pictures i have taken. I have taken simultaneous JPEGs which but these appear uneffected and the quality's fine. I have also switched all of the noise reduction settings on the camera to "off", i'm shooting with ISO's under 200, exposure seems fine, and i have experimented with all of the different shutter speed variations.
I've tried other raw conversion software as other people have suggested CS2's converter could be at fault, but this has made no difference. I know i may or may not be doing something really obvious thats causing this problem, but I would really appreciate if anyone has any suggestions as to where I maybe going wrong.
Many thanks, Rob
