Photographer Tim Mantoani released a photo book of photographers holding their most famous photographs. That's it, I've seen it all. Photographs of photographers!? Get a rope. Anyway, many of them are special and stunning, and there's lots of cool celebrity shots, and one of Mandela that gave me the chills. Mantoani's got quite a few of the photos-within-photos up at his site, and it's definitely worth taking a peek.
