My first thought is always of light.

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 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 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.

The principal rule of art is to please and to move. All the other rules were created to achieve this first one.

All enterprises that are entered into with indiscreet zeal may be pursued with great vigor at first, but are sure to collapse in the end.

Let me first state that I believe that marriage is a sacred union between one man and one woman.

Entropy theory is indeed a first attempt to deal with global form; but it has not been dealing with structure. All it says is that a large sum of elements may have properties not found in a smaller sample of them.

There is no need to do any housework at all. After the first four years the dirt doesn't get any worse.

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

I never taste the wine first in restaurants, I just ask the waiter to pour.

After the first miscarriage, I tried to take the attitude that it was my body's way of telling me that this pregnancy wasn't meant to be.

Before and during the first phase of the war his administration repeatedly maligned the UN but now, that Iraq has turned into a quagmire, it is asking the UN for help.

You look at the whole Human Rights questions, I happened to be there at just the right time when the country was awakening - this goes to the first question you asked - the whole country was awakening to a hundred years of injustice that hadn't been resolved yet.

So, first you have to be able to play with a metronome. Then you take your freedom. If you play in an orchestra, you got to watch the conductor, he is like a metronome, but it is more difficult because he can change rhythms.

My first figure was a SLAYER eagle. And the dragons and the tribals are all I have got.

We're parents first, and once you have kids, everybody knows that you have priority lists. Number one is your family and everything else just kind of finds its place.

Everything has to be pulling weight in a short story for it to be really of the first order.

But in the first Gulf war the United Kingdom was not under any threat from Iraq, and is still less so in the second one. Then there is no justification for obstructing freedom of information, particularly as nations have a right to know what their soldiers are being used for.

I sort of understood that when I first started: that you shouldn't repeat a success. Very often you're going to, and maybe the first time you do, it works. And you love it. But then you're trapped.

Working-class Americans have waited too long, close to a decade in fact, for an increase in the minimum wage. This has been the second longest period without a pay raise since the Federal minimum wage law was first enacted in 1938.

The first thing you do when you get out to center field is put up your finger and check the wind chill factor.

Christians must be Jews. The truth of what we believe depends on the truth of Judaism, depends on the first covenant.

The international proletariat first appeared on the scene in the early Thirties of the nineteenth century, and its first great action was the French Revolution of 1848.

Success requires first expending ten units of effort to produce one unit of results. Your momentum will then produce ten units of results with each unit of effort.
