These days, most nature photographers are deeply committed to the environmental message.

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.

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.

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.

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.

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.

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.

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

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.

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.

The sarcasm made a slight whistling noise as it flew over Loafers' head.

Truth is buried, deep inside of men, sweep away each day.

Occasio praeceps, experimentum periculosum, iudicium difficile."..' Opportunity is fleeting, experiment dangerous, and judgement difficult.

I don't even think about fame at all.

Learn from the masses, and then teach them.

Vodafone is building a digital stadium in Istanbul. It is really worth going to see that. The whole experience will change with the possibilities viewers will have.

We need our president to be successful because our futures are all tied to the success of America, which means America's government, which means, in essence, the president.

It's strange, isn't it. You stand in the middle of a library and go aaaaagghhhh' and everyone just stares at you. But you do the same thing on an aeroplane, and everyone joins in.

Today I may way before an awestruck world; I am still master of my fate. I am still captain of my soul.
