Is there a lot of pressure to turn pictures around quickly for clients?
"That's one of the biggest problems, actually, and it's hard to send pictures from the middle of the desert or the Himalayas. I have access to a satellite phone, but it's really expensive to use. In the mountains, I have to use it because the sponsors have invested a lot of money and they need to have those pictures. For something like the Dakar Rally, I try to find a gas station or some place in a small town on the route so that I can try to send some images back from."
Have you had any close calls or found yourself in a dangerous situation?
"My whole job is like a close call! When I'm in the really big mountains, such as 6,500 metres above sea level on K2, then everything you do is dangerous. So you have to be focused on your health and safety, but at the same time be thinking about the picture. Working alone in the desert with cars going extremely fast next to you, that's dangerous too. Most of the drivers know me and I know them, so if they see me they know that they can go close and I won't do anything stupid. But of course, anything can happen."
How do you look after your gear when you're shooting in the dust of a desert rally?
"If you don't change lenses there's really not a problem – in my experience the dust can't get inside the camera. To avoid changing lenses, I always try to use two cameras, whether I'm in the mountains or the desert. On one I have a Canon EF 24-70mm f/2.8L II USM lens and on the other a Canon EF 70-200mm f/2.8L IS II USM."
What's the hardest part of the job for you?
"Flying. I am almost two metres tall and seats in planes are getting smaller and smaller."
Where is your favourite place to take pictures?
"I really like to spend time in the mountains, so anything we can do there – be it something simple like running or more ambitious like ice climbing – is cool."
