This book is way beyond the happy snapper although it took me a long time to understand some of the techy bits and unusual ways of getting to the point. If you dont have a dslr camera and various lenses this book is not for you.
This book is supposed to be a field guide but it wont go in my camera bag. If your starting with digital photography this is not the book you need. Also to follow the book you need a good dslr and various lenses.
