Re: Excessive grain in scanned images

2002-01-26 by peter_in_seattle

There has been extensive discussion of this problem and the 
phenomenon of "grain aliasing" in general on the Usenet 
newsgroup comp.periphs.scanners, so you might post a 
message there .... It seems that this effect is far more 
pronounced on some scanners than others. Many Nikon 
scanner users say it's not a problem for them. I use a Polaroid 
Sprintscan 4000 and haven't found it to be a problem, but I've 
used a Kodak Rapid Film Scanner in the past, and the grain was 
extremely pronounced.
