To me, style is like your fingerprint. Nobody else has it.

The work is primarily subject-driven. All decisions flow from there. The photographs are all made in response to a unique subject, in particular context, at a specific moment in time. The thoughtful preparedness that defines my working method actually facilitates spontaneity and allows me to embrace surprise. I always have a game plan but view it as merely the jumping off point.

The weirdest thing to me is that magazines would never do this for their writers. They would never hire a writer who writes for another magazine; they want to have their own stable of writers. Newsweek would never hire a TIME writer, and TIME would never hire a Newsweek writer - but they would both hire the same photographer to shoot a cover for them.

I'm an artist in residence, I've still been able to accept commercial jobs, and what I'll do is I'll make little videos on the side that I then bring back to the school and show the students the next day.

A lot of the challenge and the reason for the success of those one-shot photographers is that their pictures almost have to be subject proof. Because you usually only have a few minutes with the person. You never know who's going to walk into the room - whether they're going to be friendly, grumpy, sick of photographers, or between meetings.

To me, style is like your fingerprint. Nobody else has it.

People aren't hiring just a picture, they're hiring someone they can work with. That plays a big role .
