I recently bought a fairly decent digital camera and I found I didn't know the first thing about how to use it, so besides reading the owner's manual I read this book and it really helped me understand what's going on inside the camera when I take a photo or use different settings. If you have a digital camera that allows you to do more than point and click and you'd like to gain a basic understanding of digital photography, I learned a ton from this book and highly recommend it. The camera will no longer seem overly complicated or intimidating, the book is thorough and clearly written, the author is an expert in the field. There is a 3rd edition out (my library only had the 2nd), of course the later edition of the book will be even better.
