I like to feel that all my best photographs had strong personal visions and that a photograph that doesn't have a personal vision or doesn't communicate emotion fails.

Small, portable digital cameras that exceed the performance of an off-the-shelf Nikon using 35mm slide film are further away from current reality than the proposed NASA manned Mars mission, although I expect both to happen sometime during my lifetime.

At the heart of all photography is an urge to express our deepest personal feelings - to reveal our inner, hidden selves, to unlock the artist. Those of us who become photographers are never satisfied with just looking at someone else's expression of something that is dear to us. We must produce our own images, instead of buying postcards and photo books. We seek to make our own statements of individuality.

One of the biggest mistakes a photographer can make is to look at the real world and cling to the vain hope that next time his film will somehow bear a closer resemblance to it...If we limit our vision to the real world, we will forever be fighting on the minus side of things, working only too make our photographs equal to what we see out there, but no better.

When I go to the mountains, I intuitively know my place in the world much better through these experiences. The more intense they are, the better I know myself, and the more I am able to challenge myself.

Ever since the 1860s when photographers travelled the American West and brought photographs of scenic wonders back to the people on the East Coast of America we have had a North American tradition of landscape photography used for the environment.

I almost never set out to photograph a landscape, nor do I think of my camera as a means of recording a mountain or an animal unless I absolutely need a 'record shot'. My first thought is always of light.
