The Earth is Art, The Photographer is only a Witness.

The whole world is determined by trade - which is really the blood of the world. The driving force is everyone's desire to have a better life. How? By consuming. For countries, the "Holy Grail" is economic growth.

The lions taught me photography. They taught me patience and the sense of beauty, a beauty that penetrates you.

I never lose an opportunity to speak about my obsession: humankind and the environment.

For me, an aerial picture is no different than a close-up portrait. It's a question of framing and angle. Helicopters are great for that. But I've also used planes. Of course, I always have a harness.

I'm not an expert when it comes to technology, but what changed things for me was autofocus. I used to have to throw away half my pictures because it was so difficult to get the focus right.

I learned to be a hot-air balloon pilot to take tourists over the Masai Mara Reserve in order to earn some money and finance the work I was doing with my wife, Anne. We were studying the life of a family of lions for more than two years. Taking pictures was a way to capture information we could not put in words.
