My favourite book on underwater photography. Read my review of the third edition. The fourth edition is a must get, even for owners of the previous editions (I have all four editions in my library). There is a significant injection of new content and formatting.

Jill Heinerth is one of diving's top-notch explorers. She is a first class underwater photographer, and her ability to explains technical concepts in a simple way shows through in all sorts of subjects from cave diving to underwater photography.
