I am trying to understand why anyone wouldn't like this book? Then I realized, its a person who doesn't support the notion of photographing animals in zoos, game farms, parks, etc. Other than the crusaders who don't think we should have zoos, everyone else will enjoy this book. It's packed full of detail. The tips on exposure, equipment, lighting and metering offer some of the best explanations I have ever seen.
I have been studying photography for three years now and bought this book to learn more about photographing animals. It gave me tips I could use at my local zoo with great effect. I saw an immediate improvement in my photos after reading 88 Secrets to Wildlife Photography.
Ignore the crusaders and buy this book. It's affordable, easy to read and packed with lots of great secrets!
