There is no question that photography has played a major role in the environmental movement.

When the light is right and everything is working for me, I feel as tense as when making a difficult maneuver high on a mountain. A minute - and sometimes mere seconds - can make the difference between a superb image and a mundane one.

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.

You only get one sunrise and one sunset a day, and you only get so many days on the planet. A good photographer does the math and doesn't waste either.

I think landscape photography in general is somewhat undervalued.

Theres no question that photographs communicate more instantly and powerfully than words do, but if you want to communicate a complex concept clearly, you need words, too.

The most interesting parts of the natural world are the edges, places where ocean meets land, meadow meets forest, timberline touches the heights.
