"But seeing – really seeing – has nothing to do with photography. And it rewards you with pleasure. The most important thing – and if any photographer wants to disagree with me, they can go off into oblivion – is your emotional approach.
Some people say that truthfulness is impossible in photography. But if you're in a battle in Vietnam, watching young men dying and trying to kill other men, and there's no truth in that, where is there truth? When you see Eddie Adams' picture of the police chief shooting a man in Saigon, there is absolutely no doubt in your mind that you are looking at the ultimate disgusting truth of what happened that day.
This is why I really believe photography is about making an emotional commitment to where you are and what you're doing. I try to cut out the technical side as much as possible. If you're in a refugee camp, the knapsack you carry on your back is the weight of moral obligation, and the fear of failing.
Even now, when I stand on the edge of a field here in Somerset to take a landscape picture, it's not about getting the photograph, it's about being there. Don't waste time. Look at what's in front of you."
