A highly regarded professional photographer, teacher and author, Peterson's writing style is engaging and his book is highly readable and easy to digest without being too wordy. While seemingly elementary, budding photographers and more advanced ones alike will likely find Peterson's book a great source of reference. I did find this book highly readable and a worthy investment in helping me improve my own photography skills. I do habitually try to visualise a powerful image in my mind's eye first before I release the shutter these days.
