This book is a more-or-less well written manual; however, I must admit that a lot of the information in this book is not very well presented, and often confusing (especially if this is a first time that you are encountering the subject). More detail should have been given to differences in aparture settings, and examples were lacking. Depth-of-Field was poorly explained, and while this book starts out with something as simple as a single-use camera, about 50% into it, explanations are assuming that you are very familiar with the concepts before reading this book. I must say that if I were a true beginner, I would not benefit from this book very much at all. I am not sure if there ever will be a book that will have a smooth transition from basics to advanced techniques, and will include many examples, but this book fails completely.
