Reddit mentions of Black & White: Photographic Printing Workshop

Let's see, there was Understanding Exposure, which is especially helpful for people who have only ever shot digital b/c it explains so much of the basic functions of the camera that most people take per granted and can improve your pictures dramatically, another one of Peterson's books, Learning to See Creatively is also really good, I also like The Photographer's Eye. Another really good book if you're into B&W is Black & White: Photographic Printing Workshop, which was written for using enlargers in a darkroom but can equally be used with basic Photoshop technique, shows how to convert blah pictures into really amazing imagery using basic dodging and burning techniques. I'll post some examples of his later when I get home.

I've read the 'holy trinity' (The Camera, The Negative, The Print) but I've found that I like Way Beyond Monochrome (second edition) much more. It's more modern and covers why multigrade papers are so awesome, Ansel only covers this slightly in The Print while WBM covers in in detail.

Also, for printing in general, Larry Bartlett's B&W photographic printing workshop is the best piece I've ever written. The technical side of things is covered better in other books (and here it's only covered in a few pages in the introduction chapter), but this book is a description on how a master printer approaches and prints several tricky images, as well as more normal images. I've read it several times and will most likely read it several times again.

The technical bits are easy, however. Better read photography books, for portraiture I really like the work of Inta Ruka (People I know is...magic) and Gregory Heisler (50 portraits).
