Subject: [Leica] Re: scanning B&W: salt and pepper appearance

I tracked down the origin of the salt-and-pepper texture I was seeing. It
results from trying to use unsharp masking to resolve the grain and recover
the acuity of the B&W image. Basically with the Nikon LS-2000 at 2700 dpi
you hit the salt and pepper before you satisfactorily recover the grain. For
me its especially acute with Neopan 1600.

Here's an example:
