I have to agree with R. Chester's review. I found the book to be very shallow, almost like the authors were intentionally holding back information so as to not arm their competitors. For example, on page 92, under the heading of PHOTOSHOP TECHNIQUE, there is an interesting picture of a bride, groom and a young child standing on a bridge. Very nice, but no technique is supplied. The authors refer you to page 117 for more on this image but alas, no technique there either.
I bought the book to generate some ideas as I'm new to portrait post processing. I learned a little about vignettes, converting to black and white, selective coloring, all very basic stuff. I found better info by doing a search on the web and perusing tutorial sites.
