I discovered that close to half the planet is 'pristine.' We live in towns such as London, Paris or Sao Paulo and have the impression that all the pristine areas are gone, but they are not.

I have a way to photograph. You work with space, you have a camera, you have a frame, and then a fraction of a second. It's very instinctive. What you do is a fraction of a second, it's there and it's not there. But in this fraction of a second comes your past, comes your future, comes your relation with people, comes your ideology, comes your hate, comes your love - all together in this fraction of a second, it materializes there.

I work on stories rather than individual pictures.

So many times I've photographed stories that show the degradation of the planet. I had one idea to go and photograph the factories that were polluting, and to see all the deposits of garbage. But, in the end, I thought the only way to give us an incentive, to bring hope, is to show the pictures of the pristine planet - to see the innocence.

I have tried to bring about better communication between people. I believe that humanitarian photography is like economics. Economy is a kind of sociology, as is documentary photography.

I work alone. Humans are incredible, because when you come alone, they will receive you, they accept you, they protect you, they give you all things that you need, and they teach you all things you must know. When you come with two persons or three persons, you have a group in front of them. They don't discuss with the new persons what is important to them.

The picture is not made by the photographer, the picture is more good or less good in function of the relationship that you have with the people you photograph.
