A photograph is a moment - when you press the button, it will never come back.

My photography is the result of being there at the right moment.

If you are truly successful in capturing the pulse of life, then you can speak of a good photograph.

In 1958, a year before the revolution, Magnum wanted to send me to Cuba because they had contacts with the rebels. I'd just spent six months in South America and said 'No', so I missed everything.

What counts is putting the intensity that you yourself have experienced into the picture. Otherwise it is just a document.

I never had the time or luxury to think about inventing my own colour theory. When colour came, I was interested in expressing things that happened around me in time.

Looking back, I didn't have the patience to work in fashion. I like women so much, but I was never qualified to torture them in photo shoots. You have to be really tough and brutal.

For me, Picasso was the ultimate man. He taught me that photography is all about how you approach an image: what you do and what you don't do. He inspired me to go beyond what you think is in front of you.

I witnessed the building of the Space Shuttle Columbia, the first orbiter to be launched into space.

It took me six years to get close to Picasso. I learnt a lot from him, and he was an absolute genius. He almost became my grandfather at the time. It was like he was a magician or something.

I grew up in Switzerland, in this kind of rigidity. It was Protestant, and I was rather shy. That influenced me a lot.
