Photography is a response that has to do with the momentary recognition of things. Suddenly you're alive. A minute later there was nothing there. I just watched it evaporate. You look one moment and there's everything, next moment it's gone. Photography is very philosophical.

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.

When you're on the street, and, as you're walking along, a woman turns the corner going away from you, and for an instant you have a glimpse of the side of her face, of the gesture of her shoulder, the shape of her body, and you are committed... You are in love for an instant, or your senses are rocked for an instant. That person then disappears and is lost to you forever.

[The small camera] taught me energy and decisiveness and immediacy ... The large camera taught me reverence, patience, and meditation.

'Tough' meant it was an uncompromising image, something that came from your gut, out of instinct, raw, of the moment, something that couldn't be described in any other way. So it was tough. Tough to like, tough to see, tough to make, tough to understand. The tougher they were the more beautiful they became.

Then I thought, Whoa. If there are no photographs, then there is no history. I'm going to get in there. I'm going to make these pictures. We need a record.

The thought for us [street photographers] was always: How much could we absorb and embrace of a moment of existence that would disappear in an instant? And, Could we really make it live as art? There was an almost moral dimension.
