RE: GRAIN/ICE SHOWDOWN: Nikon LS8000 vs. Minolta Scan Multi Pro!

Most films have more grain when overexposed. XP2 is one exception.

Grain magnification is not a function of exposure level but rather due to
the compression of the image. Slide film is WYSIWYG, while negative film
needs dynamic range expansion which magnifies the grain.
