Digital BW, The Print

Martin

I almost always scan at the maximum resolution of the scanner, 
in this case, 1600 dpi for the 1680. I can see the difference 
between this scanner and its predecessor, the 1600. The 
difference is not so much the resolution, but the density range, 
which is 3.6 in the 1680 and 3.2 in the 1600. The shadows are 
better and don't posterize with the 1680, whereas sometimes 
they did with the 1600 and the 800. Even the 1640SU Photo for 
$350 is pretty good. For 35mm and 120 you need more than 
1600 dpi(at least 2500) if you're going to 11x14. My number is in 
the back of View Camera and Camera Arts if you want to talk 
about this at length.
