The writing is clear and concise, as you'd expect from an O'Reilly book. Ken clearly knows a lot about his subject and litters his pages with tons of useful advice and practical examples not only of what to do, but also *why* you should be doing it this way.

Several co-workers have pestered for a look at the book, at which point they promptly went off and bought their own copies!

I'd say that you need to know a little about your digital camera, and have a passing knowledge of Photoshop in order to get the best out of this book, but I'd certainly recommend it to anyone wanting to get more from their photography.
