What is your favorite or most influential photography book?

I was asked this question in a Linkedin phtotography group. This is my answer:

1) The Ansel Adams trilogy: The Negative, The Camera & The Print. (Even if you only use a digital camera, read these books!) 

(the three books by Ansel Adams)

2) Domestic Landscapes by Bert Teunissen.

See: www.bertteunissen.com for his beautiful series of images from all over Europe:

I saw his pictures in a museum in Amsterdam in 2007 and bought the book.
It inspired me to make a "domestic landscape" portrait of my parents and it's the best portrait I have of them.

3) Barry Thornton - Edge of Darkness. I haven't read this book yet, but it is in the mail to me from the UK right now.
I've heard a lot about Barry Thornton and I'm looking forward to reading his book myself.

4) William Crawford - The Keepers Of Light. This is the "standard work" about alternate early photographic processes, like cyanotype, carbon printing, gum printing, bromoil, Van Dyke Brown, salt printing, albuminen, etc.
