I have recently started working with black and white again and I am looking for advice on some good books on the subject. Right now I am really not interested in technical books on the subject, rather I am more interested in books that may discuss how to "see" in black and white. I have been shooting color for years and I am having a really tough time recalibrating my eyesight to tones, shadows and forms. I realize it is a bit of a tall order but I thought I would throw out a feeler. I have several Ansel Adams books, he is obvously very good and they are helpful, but I am interested in getting more then one perspective on the craft. So other books recommendations would be much appreciated. Thank you in advance. And, I wouldn't doubt that this topic has probably been discussed before so any links to similar threads would also be appreciated. Unfortunately my own search skills seem to be limited.
