Re: speckly, grainy shadows, eliminating

2006-10-16 by john dean

I suspect you are using a ccd scanner like a Nikon or something like
that. Oh man, not the scanner for that film. Don't give up on the
Photoshop Noise Reduc filter though. I've saved many a Nikon scan with
that capability. It just takes some time. Make sure you are judging at
100%.

maybe it's that nasty grain aliasing affect that I read about some
scanning doing. The grain manifests itself in a pattern of speckly
white dots.
