I've ready quite a few books about photography. Most have been about how to use Photoshop to improve digital photos. However, I've also read a couple of books on how to get in to the business of stock photography (not for me) as well as how to pay attention to the things that'll make a photo memorable (still working on this). Here's my collection.
