I'm always interested in finding new aesthetic problems to deal with and challenge myself, even if the aesthetic problem is one of content.

There's something arbitrary about taking a picture. So I can stand at the edge of a highway and take one step forward and it can be a natural landscape untouched by man and I can take one step back and include a guardrail and change the meaning of the picture radically... I can take a picture of a person at one moment and make them look contemplative and photograph them two seconds later and make them look frivolous.

A work can do many things at once, and it doesn't have to be just about the world, it could also be about photography, it could be about perception, it could be an exploration of the medium. It could be a document, it could be a visual poetry, and it could be a formal exploration all at the same time.

I've been the head of the photography program at Bard College for over 30 years, and I take that as seriously as I do my photography. My time is devoted to that too.

I realize that as I get more experience as I get older, my perception changes and that feeds the photograph.

Photography is inherently an analytic discipline. Where a painter starts with a blank canvas and builds a picture, a photographer starts with the messiness of the world and selects a picture. A photographer standing before houses and streets and people and trees and artifacts of a culture imposes an order on the scene - simplifies the jumble by giving it structure. He or she imposes this order by choosing a vantage point, choosing a frame, choosing a moment of exposure, and by selecting a plane of focus.
