Technical photography books are often a bore, either dumbed down to the point where any moron should know this stuff or up in the stratosphere where it takes a genius to understand.
In "Raw Skin," however, you get a step-by-step explanation of how a true artist accomplishes his art. Not all of his methods are typical for Photoshop wizards. Indeed, his masking method offers a great and simple alternative to those used by most people. The strength of this book is that it shows us how to let Photoshop do a lot of the work for us, instead of making us work harder in a rather complex program.
Once you've mastered his basic techniques for making people look good and for creating masks, you're ready to advance into his fantasy territory. Even for people who seldom make composites, the explanations are clear and easily followed.
Acquiring all of the author's skills could take years, but improving our own skills won't take long.
As a real bonus, we have pictures of his lovely muse to illustrate all the techniques. The book is worth its price simply for the photographs used as samples.
"Raw Skin" is neither dry nor dull. But, as with anything new, it can challenge you to rethink some of your methods and to incorporate new ones into your workflow.
