This book is for people with visual imagination. If you're a scientist or engineer looking for some fast 1-dimensional formulae that will let you pop out great photos without having to stop and think long and hard about your subject and your message, you won't understand this book. This isn't a book about rules and exposure. It's a brilliant book that finally explains everything that goes into making a serious photograph — and why rules are “…mindless things that raise you quickly to a level of acceptable mediocrity, then prevent you from progressing further.”
If you are willing to expend the mental effort required to create great photographs, this is the book that explains what matters and about what you need to be thinking to create extraordinary images.
