I really liked this book. I have an expensive camera that I don't know how to use effectively so this book was perfect for me! I was able to read it in one sitting and was kept interested throughout! After the read, I feel much more confident in using my DSLR. I'm obviously an amateur and I think this book is perfect for amateur's who want to better understand the manual mode of their DSLR. This book lays it out so effectively! I now better understand aperture, shutter speed, and white balance! The author wrote this book in a way that I was able to easily understand things that I could never quite understand! I'm not sure it would be as good for those readers who already have a clear understanding of those concepts. But, either way, I definitely recommend it!
