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.

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

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

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.

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.

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