If the measure of a good book is compelling readability, then this book is a good book. Two sessions is all it took, although of course it does have pictures.
And if the measure of a good photography book is inspiring you to go out and take pictures, then this is a good photography book. Even before finishing it I was trying out some of Peterson's tips.
What I like so much about this book is that it has enough "technical" information to be really useful, but not so much as to make it dry. The author clearly loves his work (and his wife) and communicates it with bubbling enthusiasm. He's "artistic" but doesn't come across as a moody, tortured soul.
I have some technical photography books that are highly informative but also dour and depressing. By contrast this book had me buzzing and raring to go. Highly recommended!
