You can't expect to take a definitive image in half an hour. It takes days, often years.

What I loathe is the multi-national conglomerates who must take responsibility for the degradation and pollution of so much of our landscape with their factory farming and greed.

After Land I wanted to continue exploring the theme but I needed a new challenge so turned to colour. I explored Bradford and produced a series of urban landscapes that I liked, but because Land had made such an impact on the general public my colour work wasn't reviewed.

And in fact I don't believe there is such a thing as a definitive picture of something. The land is a living, breathing thing and light changes its character every second of every day. That's why I love it so much.

Look at lots of exhibitions and books, and don't get hung up on cameras and technical things. Photography is about images.

I like photographs which leave something to the imagination.

It was 1966 by the time I started taking pictures seriously and books, newspapers and magazines of the time were full of great pictures that helped to inspire me.

You can't expect to take a definitive image in half an hour. It takes days, often years.

I don't get wrapped up in technique and the like.

I hardly teach. It's more like a gathering of minds looking at one subject and learning from each other. I enjoy the process.

Born Berlin 1931, Germany, father a British diplomat, mother an American artist. Educated at various schools all over the world. 1958 Settled down to live in London. 1966 Became interested in photography through photographing my young children. No formal training.

The viewer must bring their own view to a photograph.

But I was, and still am, an avid reader and so when I first started I chose to photograph many of the great writers in this country to try and earn a living.

I have always been a very keen walker, though, and I often took a camera with me on my walks.

I've been working with the land for most of my life; walking it and photographing it. And I love it to bits.

Maybe black and white is the best medium for landscapes, I don't know.

I'm not faithful to one particular medium, and it's what I try to teach to people who work with me.

I have always loved reading, so was interested in the literary world, and took many literary portraits.

I had been working in colour for ten years or so and looked at digital and liked the possibilities it gave me.

I was surprised that the TV series was popular itself, but after that it went on to become more popular over the years and thus it seemed eventually that they would turn it into a movie.

I prefer to remember the happy things over 10 years, the things that went well. Let me see, what did go well?

What I try to do for my readers is to pass on some of the things that I found out about being thirteen after doing it for forty years.

I think I've become a much better singer and a much better player. Years and years of playing a couple of hours every day will do that.

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

The robe of flesh wears thin, and with the years God shines through all things.

The Republicans claim they are for strengthening Pell grants when the truth is that over the last four years, their legislation has done the exact opposite.

I want to thank all the fans for their support over the years. Keep supporting the Knicks, we're moving in the right direction here and we will be exciting to watch and competing against the best in the NBA. Come back to the Garden for those exciting games.

I am told that there have been over the years a number of experiments taking place in places like Massachusetts Institute of Technology that have been entirely based on concepts raised by Star Trek.

I couldn't sleep for two years, they tried to break my nerves. They used a lot of psychology to brainwash.

What the war did was give me the opportunity of three years of continuous reading, and it was in the course of reading that I became convinced that I should become an economist.

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.

We started filming in 1993 which was only four years after the fall of communism. The difference in Budapest over the last five years has been remarkable.

I had a wonderful time with the Stones but after 31 years, I thought it was time to move on.

The average life spans of many bands are not that long, up to five years if they are lucky.

For years the Trio did nothing but play for musicians and other hip people. We practically starved to death.

Had the Hebrews not been disturbed in their progress a thousand and more years ago, they would have solved all the great problems of civilization which are being solved now under all the difficulties imposed by the spirit of the Middle Ages.

There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

Plan Colombia was supposed to reduce Colombia's cultivation and distribution of drugs by 50 percent, but 6 years and $4.7 billion later, the drug control results are meager at best.

So the guy that we're really targeting our system at this year is one of the guys who brought a 16bit system three or four years ago and has pretty much had it with that, and he's ready to buy something new.

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

I have everything I had 20 years ago, only it's all a little lower.

Confidence comes from hours and days and weeks and years of constant work and dedication.

In the past 3-4 years I've developed a habit of keeping numerous small cassette recorders in my house and in a bag with me so that I'm able to commit to tape memory song ideas on a constant basis.

I've been a financial journalist for 30 years.

If Davis Cup was a little bit less or once every two years, I would be more inclined to play. But the way it is now, it is too much tennis for me.

I'd been trying for all of the eight years we'd been married to have a child, and finally I did.

I don't shop. I haven't shopped in about four years.

Yippee! I can't believe I made it. It feels like a long haul to get here. I'm so fine with it. People want you to have some sort of breakdown, but I'm relieved to be 40 years old, and I've lived a life.

It wasn't my plan to create such a record. All I did was put in the effort to win every match I played and it went on for weeks, months and years until my defeat to Ross Norman in Toulouse in 1986.
