The book is organized by photographic subject such as waterallfs, shorelines, valleys, sunset, etc. It gives advice o the lens selection, camera placement, and exposure for photographing each subject. At the end of each topic is a list of Oregon specific locations for photographing these subjects.
I can find plenty of books on how to photograph waterfalls or sunsets. What I was hoping for was advice on specific beaches or locations in Oregon. This book will not give you that. Look for places on the web for "Photograph America" and "Phototraveler" for location specific advice.
