I don't often review books, but I do know a gem when I see one. Joe McNally's "The Moment It Clicks" is clearly one of them.

This book is filled with two-page stories. On one page is a full-size photograph -- and typically these are tremendous photojournalism or studio shots by McNally, who is one of the great photographers working today. On the other side is a short explanation by McNally of how he made the image.
