I actually enjoyed all the chapters on preparation of your images and setups before tackling a compositing job, it was learning some new things mixed with reviewing/validating overall Photoshop features and workflow sequencing. I equated this book to being similar to painting a room. 90% of the work that will determine a superior quality paint (compositing) job lies in the hours spent getting the right materials, tools (images), and taping/prepping the room (prep-retouching/correcting). The actual painting (compositing) is just the almost-final step in the process, with some cleanup/tweaking at the end. Most important is to collect images with similar lighting source and image quality. It is very fakey to Photoshop-change the lighting on faces, buildings, landscapes, etc. to match other images' lighting if you don't have any artistic sense or experience.
My big gripe is the example composites in the back of the book. They were very amateurish, fakey and dorky, and did not show much of the tutorial lessons in them. One of the images of an old village countryside with a domed building - a mansion and a tree in the far background were too huge and out of proportion for their distance. I was hoping for more commercial compositing samples, like theatrical movie key art collages with FX layers, automotive brochure-type beauty shots and advertising art, and/or fantastic fantasy/sci fi composite imagery. This is not an ultra-advanced book, seemed aimed for high-beginner/low intermediate Photoshop students.
