Query: Review: "Understanding Exposure" (Revised Edition)

After a long break in amateur FILM SLR photography, I purchased this book because I thought it may offer some good advice for the DIGITAL SLR amateur photographer--- and does it ever! Bryan Peterson offers some really great advice for attaining exposures which transform normal photographs into really dramatic photographs. Whether you are into film OR digital photography, this book is worth your time and money. The author manages to use great examples of dramatically exposed photographs, then he very briefly explains how he shot it. If you enjoy taking pictures, this book fires you up; Peterson motivates you to pack up the camera and use his easy-to-understand advice to capture his visions in your own pictures. An easy, enjoyable, and enlightening read. Highly recommend.
