Digital BW, The Print

I also made a few experiments, and actually found that using the levels tool
will actually enhance grain/grain aliasing more than curves or the
burn/dodge tool. Anyway, the burn/dodge tool is quite awkward to use when
you have a large section of the image to burn or dodge, as it is incremental
(i.e. every stroke adds) so it's almost impossible to evenly darken skies,
for instance. On the other hand, curves are better than levels in general,
but it depends how steep a curve you have to apply to get the image where
you want to.
What I found can be a solution (but I'm still exploring) is to save a copy
of the image before setting black and white points, so that contrast is very
low (i.e. grain doesn't show). You can then  darken/lighten it as needed and
use it as a layer above the "correct" image, with a mask to affect only the
parts you want to, playing with the blending mode (overlay, multiply and
soft/hard light being the most effective) to fine tune the results.

Subject: [Digital BW] levels and grain


As a result of all of the posts over the last week about levels and 
grain, spent some time this afternoon experimenting with a scanned 
image that degrades easily -- a very dirty white door on a rotting 
old house.  It did appear that using curves rather than levels (16 
bit) did lessen image degradation considerably.  Is that an artifact 
of this particular scan or will hold generally?  The only problem 
with working in levels in 16 bit is that as you cannot use an 
adjustment level, there is no going back to revise what you have done.
