Ideas must be put to the test. That's why we make things; otherwise they would be no more than ideas. There is often a huge difference between an idea and its realization. I've had what I thought were great ideas that just didn't work.

I have worked with this red all over the world - in Japan, California, France, Britain, Australia - a vein running round the earth. It has taught me about the flow, energy and life that connects one place with another.

When it does get below freezing and there is - it's cold enough for ice to form, then that changes the whole landscape, and it makes the landscape a different landscape to the one that I worked with previously. And I want to understand that. But the big tension of the ice works is that they're often made when it's cold enough to freeze one piece of ice to another.

If I'm going to understand the land, I have to understand the wind, the snow, the rain, the leaves, the ice, and changes in temperature. It just reflects a reality for me.

If I had to describe my work in one word, that word would be time.

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.

Time confined into blind caves or extended through tunnels, responds to the call of infinity, which teases with its promise of freedom. outside the body, time is a pair of compasses in the hands of eternity, but inside it is a pendulum, fastened to the heart. the heart takes its measure from the lengthening swing of the pendulum surveying what time is left. in its own rhythm time spreads itself wildly here and there and is crippled elsewhere. its unequally distributed weight wounds my body - that is how the particularities of my life are manifest.
