"Climbing Mount Everest is relatively straightforward for an experienced climber," explained Robert. "I had previously attempted to ascend the notoriously difficult west ridge route but that had defeated me. So in 2001 I succeeded climbing the north face, but I must tell you that to climb Everest up the commercially popular route is easy.

"Ueli (above) is a wonderful climber, an exceptional mountaineer, we climb a lot together looking for that perfect shot that sums up the strength and balance and fitness that climbers need," explained Robert. "We go out of our way to make the photographs as difficult as possible, like in our ice-climbing route in Graubunden in Switzerland and Berner Oberland, which is also in Switzerland. His free climbing abilities are what most impresses me, he is a good friend and it is a pleasure to work with him"

"Cerro Torre (above), the 3102m peak in Patagonia, Argentina is actually considered to be one of the hardest ascents to make in the world, although it is a mountain that no one has really heard of," explained Robert. "It is all about the changeable weather there, it can turn on you in minutes. In recent years with improved weather prediction technology that mountain has decreased in danger, but like all mountains must never be underestimated"
