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 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.

My first thought is always of light.

Memory selects single important images, just as the camera does. In that manner both are able to isolate the highest moments of living.

I find it some of the hardest photography and the most challenging photography I've ever done. It's a real challenge to work with the natural features and the natural light.

I began to realize that the camera sees the world differently than the human eye and that sometimes those differences can make a photograph more powerful than what you actually observed.

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.
