GIMP 2.8 for Photographers by Klaus Goelker is a beginner’s guide to the world's most advanced open-source image editing application. A powerful, multi-platform solution running on Linux, Mac OS X and Windows, GIMP 2.8 is a fairly complex proposition. This book guides users through the new user interface and tools, the basics of image editing and simple adjustments, advanced techniques using layers and masks, developing raw images, working with the improved text tool, and preparing high-quality black-and-white images. The most important editing functions are presented in individual, easy-to-follow "workshops." Published by Rocky Nook, the 400-page volume is available for $39.95.
