"I find it very helpful to work within a defined set of constraints. In this case, I got this idea in my head to shoot a ski-action feature on 8 x 10 film—with cumbersome equipment, slow shutters and limited focus controls—basically, giving up everything action photographers take for granted and seeing where it took us. I've always loved Vittorio Sella's mountaineering images from the late nineteenth century and wanted to explore working in a much more deliberate way. The editor was very enthusiastic about the approach and miraculously managed to get the substantial overage approved. Turns out Vittorio is much more of a badass than I am."
