[Digital BW] Diffusion sheet in scanner (was Re: 40" Print, How many Megapixels?

2005-12-24 by djon43

Paul, I've got a Scanhancer, have used it with my Nikon V and slides.

Until I got Nikon's FH-3 carrier I couldn't use Scanhancer with
negatives (FH-3 uses Nikon's slide slot and light chamber which works
with Scanhancer but the SA-21 strip film carrier doesn't cooperate).

I have no observations as yet about silver B&W because I've seen no
reason for it, have been very happy with Vuescan's "slight grain
reduction" which does reduce grain while leaving it sharp.

With color slides I'm certain that there's a faint advantage to
Scanhancer Vs careful use of gaussian blur and USM, but I don't
believe it's often worth the effort because few images have ever been
improved meaningfully by diffusion enlargers or cold lamp heads,
despite Ansel's advice...Scanhancer does simulate that effect.

In additon, Scanhancer does defeat popcorn grain, which you'll get 
with large enlargements from C41 B&W films...but I find C41 B&W
plastic-looking, charmless, so I stick to my knitting with silver films.
