Digital BW, The Print

I made a similar test by placing a ruler on the glass and raising the other
end of the ruler to find the optimal focal plane with a 2450 scanner. The
focal plane was very close to 2 mm (3/32").
I'm now scanning my 4x5 negs with a 1680 Pro scanner. With that scanner you
can choose between two focal planes, i.e. 0 and 2 mm (3/32"). I lay the
negative emulsion side down on the glass and keep it flat with an antinewton
treated piece of glass on top.

here's and article showing why your probably *don't* want to lay your
negatives on the glass:

(see Focus and Spacing)

This made a big difference in the quality I get out of the scanner.
