I had the honor of editing a textbook written by a friend of mine. The Architecture of Light, by Sage Russell, is a lighting textbook that focuses primarily on lighting design and not just the physics of light. Because of the excellent presentation of design principles, I have decided to use this text as the book for my lighting design class.
Sage has taken his experience as a lighting educator and developed a unique method of presentation for many of the topics. Specifically, the light mapping technique is a proven method of presenting lighting concepts and one I use on a regular basis.
I would not only recommend this book to students of lighting design, but I think even experienced designers will gain a new perspective of their lighting design process. I urge anyone in the lighting industry to take a look, given the opportunity- you will not be disappointed.
