This book contains one or two relatively easy methods for getting great color from certain types of digital photos. The first is: convert to the LAB color space, sharpen the L channel with Unsharp Mask, and steepen the A and B channels with Curves. Done aggressively, it works wonders on images with subtle color variation, like photos of canyons. Done subtly, it works better than goosing the saturation if you want to make colors snap.

Beyond that, you're getting into some deep water, and the book contains a lot of the information you need to navigate those depths. Unfortunately, the writing is quite opaque thoughout most of the book, and the pages are laid out so as to be extremely difficult to follow at times (e.g., the photos and illustrations are often two pages away from the text describing them). Margulis and/or his editors need to reread their Tufte.

I give it four stars for having some bits of great content, and two stars for presentation.
