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.

At its most successful, my 'touch' looks into the heart of nature; most days I don't even get close. These things are all part of a transient process that I cannot understand unless my touch is also transient - only in this way can the cycle remain unbroken and the process be complete.

Time gives growth, it gives continuity and it gives change. And in the case of some sculptures, time gives a patina to them.

I take the opportunity each day offers.

I can't edit the materials I work with. My remit is to work with nature as a whole. I find nature as a whole disturbing. Nature can be harsh – difficult and brutal, as well as beautiful. You couldn't walk five minutes from here without coming across something that is dead or decaying.

You must have something new in a landscape as well as something old, something that's dying and something that's being born.

The main source of my income is through the commissions of the large-scale works and big sculptures, the projects.
