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

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.

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.
