I'm pretty familiar with some of the basic functionality of Photoshop. Stuff like cloning, resizing and the like are easy. But I see some work from others and can quickly tell that they know this tool much better than I do. Does anyone have a suggestion on a book or two that covers some of the more intermediate to advanced features in Photoshop? I'm looking for something along the lines of a "how-to" teaching style. One that covers the latest Photoshop CS would be preferred. Thanks for any input you can offer, Ed
