This book will teach you absolutely everything you need to know to be able to process your photos like a pro with CS4, even if you've never worked with Photoshop before. Well-written and easy to understand, it's filled from cover to cover with easy to follow, step-by-step explanations. It includes an excellent DVD also packed with information, as well as the photos that are in the book, so you can practice the techniques presented by the author on the exact same photo to ensure you get the same results. This book is worth every penny! I highly recommend it!
