SEBASTOPOL, Calif. -- Two books will be making their debut at Macworld 2009 -- just in time for all of the photographers and graphic designers present at the show. Lesa Snider King's Photoshop CS4: The Missing Manual (O'Reilly Media, $49.99) covers the newest version of Photoshop and teaches you everything from editing photos to creating beautiful documents -- whether you're a beginner or a power user ready to try some advanced techniques.

"Lesa's book is a great resource for Photoshop pros and newbies alike," says Missing Manuals Editor Dawn Frausto. "For people who are new to the program, she explains basic concepts like resolution that folks need to understand when working with images. For experienced Photoshop jockeys, Lesa guides you through advanced techniques and explains all the features that are new in CS4."

The newest installment to Deke McClelland's renowned One-on-One series will be there as well. Photoshop CS4 Channels & Masks One-on-One (O'Reilly Media, $49.99) contains a unique combination of step-by-step text lessons, DVD-video demonstration and real-world projects. You'll quickly learn how to select and composite highlights, shadows, clouds, fabric, flame, eyes, hair and more. Digital Media Editor Colleen Wheeler says about this book, "I've never seen 500 pages like this. It truly delivers on its deep-dive promise and it's gorgeously crafted."
