You can't expect to take a definitive image in half an hour. It takes days, often years.

I've been working with the land for most of my life; walking it and photographing it. And I love it to bits.

I hardly teach. It's more like a gathering of minds looking at one subject and learning from each other. I enjoy the process.

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

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.

It was 1966 by the time I started taking pictures seriously and books, newspapers and magazines of the time were full of great pictures that helped to inspire me.

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.
