Digital BW, The Print

The technical coverage on this subject has (as usual) been excellent.
 

One piece of advice I'd give is to judge in the print (at "normal"
magnification), not on the screen.   One can get tied in knots with
the vast range of interpolation/sharpening options available, not all
of which make that much difference in a print at normal viewing
distance.   Until (unless) you know how the screen view transfers to
the print it is safer to judge in the print.

Fortunately, as usual, most options have free trial versions, it is up
to you to decide whether a little extra noise is good or bad in your
prints, or if a harder/softer approach to edges works well in your
images.  

Apologies if someone already mentioned this and I missed it.
