I use GIMP for some of my image editing but I never really knew the capabilities of the program. After working through this book, I was blown away by the tools and options GIMP had to offer. Needless to say, it may be better to just stick with GIMP and save my money than to buy Photoshop for hundreds of dollars.
The content was neat, informative, direct, organized, and easy to follow. The pictures are colored and I like how most of the pictures in the examples are reused throughout the book. I also like how they use examples on pictures of real people so you can actually see the effects of tools, details, and etc. There is a good balance of information and pictures so you can maneuver through the book without feeling overwhelmed.
The book covers many areas such as photograph retouching, colorizing/personalizing images, logo creation, composite photography, and much more. Has an amazing table of contents so you can easily find what you need and reference it when needed. Also, the appendices include a lot of extra helpful information such as tips and hints for exercises within the book, resources, frequently asked questions, and how to install GIMP in various Linux distributions.
