RE: Proposal for Scanner Comparison

["gary" <gsellani@xxxxxxxxxxxxx>]

You might want to think about what the image should be in each photo. In the
past, I've done experiments with various people by photographing $20 bills,
that is something everyone had handy. Not full frame as you might get in
trouble, but a good shot of Andrew Jackson.  These product nice high
contrast images. Perhaps you can think of a common household item that will
produce continuous tones.

Also, don't you want to vary the type of film as well? Can this be opened up
to 35mm scanners later once you establish a baseline on the high end
scanners. It would be interesting to see how the various 4000ppi scanners
compare (ss4000, ss4000 plus, artixscan 4000t and the canon 4000ppi
scanner.).
