unfortunately for you and your assertions, if you actually compare the scans
you will see that both the 4000 dpi scan and the drum scan pull off a great
deal more detail from the neg, even from a 400 asa film. Very, very visible
in enlargements greater than 8x10 from 35mm.

Of course I could be lying.
