For Christmas, I got a copy of John Beardsworth's "Advanced Digital Black and White Photography." It's probably the single most useful book on photography I've read, and most of what it discusses is as applicable to color as to black and white. Post-processing whizzes might not learn much from it, but those of us who are challenged in that regard may. Among the things I learned (that most of you probably knew) was how to set the white and black points with a levels layer. Shazam, previously muddy photos looked much better. He also gets into adding local contrast via multiple curves layers and masks rather than dodging and burning. That had me re-processing a number of photos with much better results. He apparently also has a different book called "Digital Black and White Photography." Don't know anything about that one.
