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

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

My first thought is always of light.

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.

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.

Today, I'm very careful not to mention very specific locations when I write or give captions.

I began taking pictures in the natural world to be able to show people what I was experiencing when I climbed and explored in Yosemite in the High Sierra.
