Look at lots of exhibitions and books, and don't get hung up on cameras and technical things. Photography is about images.

I'm not faithful to one particular medium, and it's what I try to teach to people who work with me.

I have always been a very keen walker, though, and I often took a camera with me on my walks.

I don’t get wrapped up in technique and the like. I have a simple rule and that is to spend as much time in the location as possible. You can’t expect to take a definitive image in half an hour. It takes days, often years. And in fact I don’t believe there is such a thing as a definitive picture of something. The land is a living, breathing thing and light changes its character every second of every day. That’s why I love it so much.

I had been working in colour for ten years or so and looked at digital and liked the possibilities it gave me.

I had no aspirations to become a landscape photographer at all. In fact it was portraiture that was my beginning, I suppose. I have always been a very keen walker, though, and I often took a camera with me on my walks. But I was, and still am, an avid reader and so when I first started I chose to photograph many of the great writers in this country to try and earn a living.

What I loathe is the multi-national conglomerates who must take responsibility for the degradation and pollution of so much of our landscape with their factory farming and greed.
