This book could equally well be named Understanding Exposure and Photographic Composition. Printed on high-quality paper, the images Peterson uses to illustrate his points are all great examples not just of correct exposure, but also of photographic composition.
The author's style is engaging and right from the start, I found myself reaching for my camera to try out his suggestions.
Not only is Peterson a great photographer, he is also a great teacher projecting his enthusiasm for photography onto the reader.
I found this book a more compelling read than any edge-of-our-seat thriller I ever read, only putting it down to go out and shoot some photographs.
After reading this book, I no longer let the camera make my exposure decisions - choice of Aperture, Shutter speed, ISO setting are now concious decisions with a particular effect in mind.
If you want to move from "point & shoot - unpredictable result" to "think, compose, point, shoot - expected result", this is a worthwhile investment.
