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.

When we tune in to an especially human way of viewing the landscape powerfully, it resonates with an audience.

The combination of pictures and words together can be really effective, and I began to realise in my career that unless I wrote my own words, then my message was diluted.

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

I think landscape photography in general is somewhat undervalued.

I almost never set out to photograph a landscape, nor do I think of my camera as a means of recording a mountain or an animal unless I absolutely need a 'record shot'. My first thought is always of light.

There is no question that photography has played a major role in the environmental movement.

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.

The reason that I keep writing is that all my most powerful messages about the fates of wild places that I care about need to have words as well as images.

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

I began to realise that film sees the world differently than the human eye, and that sometimes those differences can make a photograph more powerful than what you actually observed.

Wanting to take a light camera with me when I climb or do mountain runs has kept me using exclusively 35 mm.

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.

What I mean by photographing as a participant rather than observer is that I'm not only involved directly with some of the activities that I photograph, such as mountain climbing, but even when I'm not I have the philosophy that my mind and body are part of the natural 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.

There's 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.

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 first thought is always of light.

And most of my early pictures failed but about one in a 100 somehow looked better than what I saw.

Ever since the 1860s when photographers travelled the American West and brought photographs of scenic wonders back to the people on the East Coast of America we have had a North American tradition of landscape photography used for the environment.

I'm exchanging molecules every 30 days with the natural world and in a spiritual sense I know I am a part of it and take my photographs from that emotional feeling within me, rather than from an emotional distance as a spectator.

I remember when an editor at the National Geographic promised to run about a dozen of my landscape pictures from a story on the John Muir trail as an essay, but when the group of editors got together, someone said that my pictures looked like postcards.

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.

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

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.

Luckily, many other people tell me how they have had a particular landscape photograph of mine in their office or bedroom for 15 years and it always speaks to them strongly whenever they see it.

I think that cognitive scientists would support the view that our visual system does not directly represent what is out there in the world and that our brain constructs a lot of the imagery that we believe we are seeing.

There is no executive order; there is no law that can require the American people to form a national community. This we must do as individuals and if we do it as individuals, there is no President of the United States who can veto that decision.

Young people discovering their sexuality must know they walk with a strong tradition and that they are not alone. They have a right to information without being pressured.

Many are needed to plant and water what has been planted now that the faith has spread so far and there are so many people... No matter who plants or waters, God gives no harvest unless what is planted is the faith of Peter and unless he agrees to his teachings.

DJs and people in the street know what they like.

People who keep stiff upper lips find that it's damn hard to smile.

Some people are directors and I think they should stay behind the camera.

We dominated Survivor - there is no way we would not dominate that, too. I can see it already, us making deals with people. That's the best part, and with the Race, it would be even more fun because I've got a lot of tricks up my sleeve.

I'm getting a wider circle of fans now. More women, more middle class people.

We must support initiatives that provide clear, concrete measures and milestones that our troops need for defeating the insurgency, building up Iraqi security forces, and handing over Iraq to the Iraqi people.

Yeah, that's what kind of, we get the idea a little bit yeah, because other people from different countries also try as hard as they can to get a medal or a gold medal in the Olympic Games. And you know, if they can work hard, we can work hard as well.

Well concerning the world records that I did, I think it helps a lot to me, yeah. I think it's a very individual thing because I heard some people say, like, oh I don't like it at all. But I definitely, for me it really made a big difference.

My goal is, of course, for this show to do well, and I would love it if people liked it.

I hate wasting people's time.

Religions get lost as people do.

I also do not like the idea of soft money, these issue ads - people don't know where the money is coming from, millions and millions of dollars outside of the control of a candidate - there's no accountability.

The people of England are the most enthusiastic in the world.

The avantgarde are people who don't exactly know where they want to go, but are the first to get there.

My theory is if you have a religion, it's a good one. Because some people don't have any at all.

It's sometimes shocking to find out what people really believe in.

That's Tommy, this great producer who comes in contact with people and must have a mental library of personnel who are great for this and great for that, and he brought this whole group of musicians to the project that I'd never worked with before.

Rock and rollers can get you the youth buzz, and younger people are fanatical readers.
