The Book of GIMP: A Complete Guide to Nearly Everything

For many photographers, Adobe Photoshop is a must-have in their digital post-processing workflow. Unfortunately, Photoshop is not cheap. For those photographers who are finding Photoshop's price tag to be a significant barrier, there is a free alternative - GIMP (GNU Image Manipulation Program).
 
From GIMP's website:

"GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.
 
It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.
 
GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted."

While GIMP does not offer the latest features found in Adobe's Photoshop, it is a very powerful and capable image editing program. Unfortunately, GIMP's interface is not as user-friendly as Photshop's. For someone who is used to working in Photoshop, GIMP can be especially cumbersome.
 
Thankfully, there is a book that may be able to help:
