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

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.

Socialism proposes no adequate substitute for the motive of enlightened selfishness that today is at the basis of all human labor and effort, enterprise and new activity.

I am tomorrow, or some future day, what I establish today. I am today what I established yesterday or some previous day.

If I had to come up with something that just came to me, I think growing up in a small town, I want knowledge. I still think today, knowledge is one of the keys.

There's more than a few remnants left in German welfare policy today. Many Germans eagerly condemn Hitler's fascism but won't examine the other reasons why the Third Reich succeeded for a season.

Compared to today's salaries, our cut was minuscule but it was very good for the time.

The NFL today has bigger, stronger, bodies than ever, moving faster than ever, hitting a stationary object harder than ever before - so the physics of the hit have changed.

The President of today is just the postage stamp of tomorrow.

I'm so happy because today I found my friends - they're in my head.

I don't know where the stock market is going, but I will say this, that if it continues higher, this will do more to stimulate the economy than anything we've been talking about today or anything anybody else was talking about.

I'm not up on today's television for children, because it's mostly cartoons that don't seem to interest me.

We aim in the domain of politics at republicanism; in the domain of economics at socialism; in the domain of what is today called religion, at atheism.

Today's interpretations of religion are often backward and contradict the needs of civilization.

The most profound, tangible influence in my life has been my wife, Monique. I don't know that I would even be alive were it not for her, and I certainly would not be the person that I am today.

Were you to read the British press today, you would learn that the British Empire never forgets its defeats.

As patients and consumers, we are better informed today about our health care than any previous generation.

A couple of guys won Academy Awards for the things that I turned down. Today, after coming to terms with everything, after being in therapy for a long time-there are areas where I will compromise.

I know the history of the record business so well because I followed Billie Holiday into the record studios. It was so primitive compared to the sophisticated business today.

Especially today as we fight the war on terror - against an enemy that represents hatred, extremism and stands behind no flag - we need to remember the sacrifices that have gone into protecting our flag.

The investor of today does not profit from yesterday's growth.

The Lord gave us Ten Commandments, but the bill before the House today gives us 39.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.
