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.
Wanting to take a light camera with me when I climb or do mountain runs has kept me using exclusively 35 mm.
We mountaineers always live with the feeling that we came on the scene too late.
My advice for climbers or photographers is to really tune into your own passions and not just what other people are doing or aren't doing. Figure out what works for you, what turns you on, what gives you the greatest amount of energy and feeling of satisfaction.
When I go to the mountains, I intuitively know my place in the world much better through these experiences. The more intense they are, the better I know myself, and the more I am able to challenge myself.
