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.

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.

We mountaineers always live with the feeling that we came on the scene too late.

My first thought is always of light.

And most of my early pictures failed but about one in a 100 somehow looked better than what I saw.

A lot of people think that when you have grand scenery, such as you have in Yosemite, that photography must be easy.

The landscape is like being there with a powerful personality and I'm searching for just the right angles to make that portrait come across as meaningfully as possible.
