RE: [APML] Film Scanability

["Dale Ireland" <direland@drdale.com>]

Hi
It isn't grain, it is noise from the sensor chip on the scanner due to the
limited dynamic range (3.2) of the scanner. making two scans, one for the
light areas of the negative, and one for the dark, then layering them
together will help reduce the problem a little.
