Digital BW, The Print

16 bit is essentially irrelevant. Nikon's 4000ppi and
the defunct Minolta's 4000ppi seemed identical in my
tests to Minolta's alleged 5400ppi, though the latter
does make a much bigger file. Obviously, the alleged
higher numbers from flatbeds and discount scanners do
not suggest they are even equal to Nikon. Several
"lower resolution" drum scanners reportedly do better
than Nikon.
