[Leica] 20D B&W

[bdcolen at earthlink.net (B. D. Colen)]

That depends upon a number of things, Daniel - The first is, of course,
the size of the print. The second is the quality of the printer. And the
third is what you do to those areas in terms of dodging and burning. If
you have an underexposed, noisy area without detail you want or need to
keep, you can eliminate the noise/grain by burning it in. But if you're
looking at an image at 50-66-100% on screen and see it as noisy, but
then printing it at a fraction of that, you may not see any more noise
than you would see grain in a film image, and therefore don't notice it.

But BD ... how much of that noise is seen in a print?

I have some really noisy files but when they are printed out you can't
even find it. I just noticed that recently.

When I edit the files in fullsize on the screen I think "that will look
really bad". But when I print them out, I just don't see it anymore.
