Digital BW, The Print

Austin/Bill

I have sent to each of you copies of two scans. Each a 300% enlarged section
of a 6x6 negative. One scanned at 4000dpi @100% and the other at 364dpi at
24"x24". Can either of you see any difference other than contrast as one
Iadjsuted earlier? I can not see anything that would lead me to believe that
the scanner is softening or rezzing up the 364dpi scan.

Mike
