Tim Mantoani's new book titled Behind Photographs, shows off the faces of the photographers too.

The San Diego-based photographer has created over 150 of these portraits over the past five years, using one of only a few remaining large format 20x24-inch Polaroid cameras. The book gives the world a glimpse of the talented photogs responsible for some of the most iconic photos over the past few decades.

The photographers above, Jeff Widener, is responsible for the Tiananmen Square Tank Man photo in 1989, and Neil Leifer, with his shot of Ali posing over Sonny Liston in 1965.

Behind Photographs is available in two versions: a $60 signed regular edition, and a $100 signed exclusive edition that includes a protective slip case. [Behind Photographs via Wired]
