A friend loaned me the older version of this book, and I was amazed at how much help it provided. Even though the old book was based around film cameras, the fundamentals that were taught and the example pictures were very, very helpful. This book is an almost complete update, with most sections rewritten, several new subsections added with specific information for digital users, and has a slew of new example photographs.
This book is even better than the old edition, and expands on some of the topics that were only briefly touched on in the first book. One in particular that sticks out in my mind is that he explains the "don't care" apertures of F8 and F11 that he uses often. The old book mentioned it in passing, but I don't recall an explanation on why those apertures were useful. There is a short section on just that in this book and suggestions on when to use them.
Full color photos are used throughout the book, and are a great help in understanding the concepts that he talks about. Each picture has a caption with the information used to take the exposure. He shows you the same picture with different settings so you can see the effects the settings have on the exposure.
I find the book pleasant and easy to read. The tone and writing are very agreeable and easy to follow. While some aspects are technical, they are written in a manner that makes them easily understandable.
This is all about how to capture the image, not processing of the image after it is captured. There is brief mention of pushing or pulling film and the effects it can create, but in general, this is about how to get take a proper picture. If you are looking for a book on how to process the picture after you have taken it, this is not the book for you.
I can not recommend this book enough if you are interested in photography. I don't know how useful it would be for professionals, but for the person just starting out or serious amateur, I can't see how you could go wrong with this. While all of the information can be applied to SLR cameras (film or digital), the majority of it can be applied to the point and shoot cameras of either variety as well.
