You look at it [a photograph] and all around the real world is humming, buzzing and moving, and yet in this little frame there is stillness that looks like the world. That connection, that collision, that interfacing, is one of the most astonishing things we can experience.

I think about photographs as being full, or empty. You picture something in a frame and it's got lots of accounting going on in it-stones and buildings and trees and air - but that's not what fills up a frame. You fill up the frame with feelings, energy, discovery, and risk, and leave room enough for someone else to get in there.

A lot of what I am looking for is a moment of astonishment, he says. Those moments of pure consciousness when you involuntarily inhale and say 'Wow!'

One of the things I learned on the street was to trust life and to keep hands off of it, and that feeling continues in the rest of the works that I do, the portrait, the landscapes, or any interest that I have. Things are good enough as they are, there's no reason to tamper with them.

Making any statement of your feelings is risky. It's just like making pictures.

I photographed the entire thing in color because to photograph it in black and white would be to keep it as a tragedy. Because there is a tragic element to photographing, in this case not war, but the collapse. It was just destruction.

Photography is about being exquisitely present.
