Let me quote myself http://www.botzilla.com/photo/G1gear.html
"As a boy, I had a neighbor who was a shooter for the local paper. I babysat his kids and devoured his library of photo books. He reminded me: 'it's not about the equipment, it's about the people.' He's gone on to become the photo editor of National Geographic, so he must have known what he was talking about!"
Whenever I see lists of "the greatest photographers," there's usually only one name that doesn't focus on shooting photos of people (Adams). If you restrict "photographers" to "PJ's" the list is quite empty.
Even for grand physical events like, say, the WTC attack, the really indelible lasting images are those of the tiny people, not the massive pile of concrete and steel. Let me steal another web reference: http://www.esquire.com/features/arti...falling_1.html
