I don't know about you, but the only thing I have bought more of (and been more disappointed by) than camera bags, is books about lighting. Just got a book that makes up for all the rest of the ones I've read. Steve Bavister, Lighting for Portrait Photography Unlike most books, all the pictures are NOT his, which means that you get examples of a very wide range of styles and approaches instead of a tremendous amount of detail on how one photographer views the world. For each picture, you get a discussion of why the approach was chosen, a diagram of the layout, shooting info, and a big full page image. The portrait examples are a bit on the "hipper than hip" side - I can't remember the last time I saw so many cross processed images in one place - but you get to see an amazing amount of creativity with relatively modest setups. Don't usually get so enthusiastic about "how to" photography books. This one is different.
