This book is terrible. I should have realised looking at the cover image that it wasn't going to be a great investment but the other reviews changed my mind.
So I'd ask you to do the same: would you want to be credited with taking that image on the cover of an out of focus lady and a blurry cat? If the answer is yes, grab it and be happy, if not, then steer clear! Every photo in the book is awful, I was willing to keep it if they were 50% decent but most look like they have been taken with a Polaroid camera, no lighting know how necessary. The lighting set-ups they discuss are pitifully simple and wouldn't cut it in the professional world or suit someone who would like their photos to be profitable at some stage. The diagrams were drawn at bizarre angles and don't follow the standard lighting diagram layout being used today (See Light & Shoot for these, I got this at the same time and am very happy with it). Most of them just show a subject standing by a window and the photographer taking their picture by it - you don't need this book to learn that!
I mostly bought this book to see the lighting set-ups of different photographers and shots so I didn't read much of it before returning. However, for me, photography is a visual process and the learning of it should be the same too. If more than a two light set-up is too complicated for the author to explain in a diagram, that author isn't likely to be able to teach me anything I don't know about photography. If you're a beginner and you are really interested in understanding how to use better lighting but aren't going to be investing in any studio or strobe equipment soon then have a look at Perfect Exposure. It contains the technical know-how to capture great shots with any light available, window or no window ;)
