Here's a foolproof way to sell a book of photographs: reconceptualize the best ones in the world. That's what photographer Tim Mantoani has done with his new book "Behind Photographs," a compilation of famous photographers holding their famous works. Mantoani, a San Diego-based commercial advertising photographer, came up with the clever concept as a way to pay homage to his distinguished, often hidden, colleagues. The project wasn't cheap -- Montoani used a rare, enormous type of Polaroid at $200 a portrait, hoping to preserve an endangered technology and entice his savvy subjects to sign on with one stone.
