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.

One of the biggest mistakes a photographer can make is to look at the real world and cling to the vain hope that next time his film will somehow bear a closer resemblance to it...If we limit our vision to the real world, we will forever be fighting on the minus side of things, working only too make our photographs equal to what we see out there, but no better.

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.

Small, portable digital cameras that exceed the performance of an off-the-shelf Nikon using 35mm slide film are further away from current reality than the proposed NASA manned Mars mission, although I expect both to happen sometime during my lifetime.

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

My first thought is always of light.

When the light is right and everything is working for me, I feel as tense as when making a difficult maneuver high on a mountain. A minute - and sometimes mere seconds - can make the difference between a superb image and a mundane one.
