Image editing has become a key element in the photographic workflow. Image editing tools, most notably Photoshop, are sophisticated and deep applications-and fairly expensive.

The only open source tool in this market is the GIMP, which has developed into a powerful multiplatform system, running on Linux, as well as OS X and Windows. This beginner's guide to GIMP has evolved from classroom materials the author developed and used in courses and workshops on image editing.

Topics include the basics of image editing and simple adjustments, as well as advanced techniques using layers and masks, stitching of panoramic images, and preparation of high-quality black and white images.

The most important editing functions are presented in individual, easy-to-follow workshops.
