I should start by saying this is a book for those who are serious about B&W and their art. If you are looking for a guide with 10 quick and easy tips for better B&W, this book is not for you. If you are into using Lightroom and Photoshop to do conversions and want to step it up to the next level by studying how one of the best does it, you want this book. Although it is brief it isn't light reading and I'm sure you will learn something that benefits your work even if you are already an advanced digital photographer. The insight into his thought process and methods alone are worth studying. I recommend it highly.
