If you are looking for a comprehensive and easy to understand book on digital wildlife photography look no further. I have a couple of other books by this author, not only is his photography ahead of the field but he can write too. Whether you are reasonably experienced with the digital workflow or picking up a digital camera for the first time, this book is a mine of information that is easily understood and very accessible.
The chapters on RAW workflow were particularly helpful to me and have been written so they won't go out of date in a hurry. The artistry in the pictures is fantastic and the book is worth buying for those alone.
