There are only a few books that I find myself going back to reference over and over. This is one of them. Many light placement diagrams with the resultant photo make this an excellent quick reference guide. The author stimulates the reader to attempt new combinations. My only objection is the use of many white bookends. Those are not staples in most studios. Also, reflectors do not accomplish the same result. I would have preferred more diagrams without the bookends. Maybe I will buy my own now. But, where to store them.
