After reading several photo books, this was the one that finally let me take control of my camera and get away from all of the auto modes. The chapters on flash, for the first time, gave me an understanding of how flash works and how to manipulate it in both TTL and manual. Contains info on design and composition as well as approaching wildlife, but it was the exposure and flash info that made it an invaluable reference for me.
Joe has done a very good job in writing this book explaining the basics of exposure control in the field including some flash techniques. I find this book to be indispensable in my library. I am now reading through it the second time. The pictures in this book are all very inspirational and well taken. I certainly recommend this book to anyone who is interested in wildlife and nature photography.
