My approach to photograph is kept simple, almost routine. All work, good and bad, is documented. I use standard film, a standard lens and no filters. Each work grows, strays, decays-integral parts of a cycle which the photograph shows at its height, marking the moment when the work is most alive. There is an intensity about a work at its peak that I hope is expresses in the image. Process and decay are implicit.

The first snowball I froze was put in my mother's deep freeze when I was in my early 20s.

I can't edit the materials I work with. My remit is to work with nature as a whole.

The stones tear like flesh, rather than breaking. Although what happens is violent, it is a violence that is in stone. A tear is more unnerving than a break.

Sometimes you need to stop doing something to really see it afresh.

If you've ever come across a tree that you've lived with for many years and then one day it's blown over, there's incredible shock and violence about that.

It's frightening and unnerving to watch a stone melt.
