[APG Public List] Digitizing 35mm slides

My testing of a similar solution six years ago failed. Since imaging 35mm
slides involves so much magnification I found that slight imperfections in
the backlight material affected the final digital image in noticeable and
negative ways. I took a 20+ magnifier to two sorters and one passive viewer
and was astonished at how imperfect the media were. The three I tested were
all white translucent plastic and were most likely made for general viewing.
I did not test any glass sorters, so they might return much different

Yes, exactly.  The trick is to make sure the camera is squared up with the 
sorter.  Also position the slides so that all are evenly lit.  I don't use a

close up setting on the camera, but you could if you wanted to do a smaller 
group (or a single) instead which would give you a higher resolution result

a slide sorter, or a homemade light box/table, anything with a translucent 
surface that can be backlit
