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

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.

When the magic hour arrives, my thoughts center on light rather than on the landscape. I search for perfect light, then hunt for something earthbound to match with it.

Often when I walked alone in the mountains, I tried to make sense out of the two halves of my life. What went on in the city during the week seemed chaotic and unrelated to the events in my mountain world.

My mountaineering skills are not important to my best photographs, but they do add a component to my work that is definitely a bit different than that of most photographers.

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 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.
