I've been going through the lessons and this is probably the most helpful Photoshop book I've read in years. Each lesson starts with a RAW or JPG image. Kelby takes you step by step through the process beginning with Adobe Camera RAW and then finishing up in Photoshop CS3.
Here are a few before and after examples from the lessons I've completed. These are not my original images. These images we're provided as part of the book.
