Scott Kelby unveils photoshop channels in this book. As usual, Scott interjects his own brand of humor, which occasionally is actually funny and often is just extraneous to the subject. Scott, however is straight forward and very clear with regard to step by step instruction on using channels in photoshop. He covers many different ways in which channels can be used to enhance photo's as well as masking and some special effects. This book will be very helpful to both beginning and intermediate photoshop users, it is easy to read and you can follow along with the example photos you can download from Scott's web site.
