This book is really more a reference encyclopedia than a textbook.
The author is clearly very knowledgeable about light theory, the history of light, and the different types of lights that are available. I suspect much of the basic information provided on the different construction of various light bulbs will neither be of interest nor much use to most photographers.
However, there are several valuable chapters such as “Light and Shade” and “Controlling Light” that are well worth reading. In addition the sections on hard and soft light, direct and indirect light are very useful.
I feel this is an excellent supplementary text for anyone learning photographic lighting. For schools teaching photography, I’d recommend they include this book in their libraries.
This book is the complete package. It contains a DVD that provides all three versions (Windows, MAC, and Unix) for GIMP. In addition there is an introduction to GIMP 2.8 which is currently under development. And last, but hardly least, the images used in the book’s tutorials are included.
The book progresses in an A to Z fashion in teaching one about GIMP. In addition to the “how to” instruction, there is sufficient, but not overwhelming, information on theory, the “why” part of processing.
GIMP is the “high end” of free photo processing software and approaches Adobe CS 5 in its capabilities. Even if you are not on a budget, consider GIMP. And if you do, or if you are currently using GIMP, add this book to your library. You’ll be glad you did.
