One big advantage Photoshop professionals have always had was the understanding of channels. It was their secret weapon, and it enabled them to do things, and work in an entirely different way than their competitors, and maybe that's why the secret power of Photoshop's channels has been such a closely guarded secret. Until now. Award-winning, bestselling author Scott Kelby (Editor of Photoshop User magazine) shows you how to unlock the power of Photoshop's Channels and really start using Photoshop like a pro. But this isn't a book of theory and technical explanations, this is a step-by-step project-based book that will teach you exactly how to the pros use channels in their everyday work (Using channels is one of the secrets they use to get twice the work done in half the time). You'll learn how today's top photographers and graphic designers employ channels to make impossible selections, to speed their production workflow, to color correct images, to mask images, to create stunning color to black and white conversions, and to do dozens of inside tricks that set them apart from the field. There's a reason there's always been a mystique to using channels, and why Photoshop users who understand and use them stay on the cutting edge. Now, their secrets are revealed using the same plain-English style that has made Scott one of the leading Photoshop authors and instructors in the world today. You'll be amazed at not only what you're able with channels, but you'll love the competitive advantage that using channels will give you. If you're ready to take your Photoshop skills to the next level, you're holding the book that will take you there, and you're gonna love it! http://rapidshare.com/files/138028171/channel.rar.html
