Hi, I've found with portraits that I am often having difficulty getting smooth gradations in caucasian skin tones without posterization - and I've been using a Canon G5 camera in the last couple of days and have just found that the same tone of grey in the overcast sky - about the tone of a grey card - has attracted noise, but the rest of the photo has not. This seemed an odd coincidence. I suspect it is just a coincidence, but it seemed interesting. Details: Epson 1200, UT inks Minolta 5400 scanner with Vuescan 35mm cameras and Canon G5, 50 iso. 1. Is this sort of mid-grey tonal gradation often a problem area? 2. Could it the posterization very likely be improved if I installed Linux and ran Quadtone Rip? 3. Any other suggestions??? thanks, Richard -- http://smallfield.vze.com http://photos.smallfield.vze.com "A liberal is someone who won't take his own side in an argument." --anon
