It is very hard to say where you're going until you get there. That kind of thing is based very much on instinct. As a photographer, one of the most important lessons I have learnt is that you have to learn to listen to and trust your own instinct. It has helped to guide me - this far at least.

If I can upset people, if I can ruin their day, then I have done my job.

If there is something occurring that is so bad that it could be considered a crime against humanity, it has to be transmitted with anguish, with pain, and create an impact in people - upset them, shake them up, wake them out of their everyday routine.

If you want to connect with people who are in distress and great grief and scared, you need to do it in a certain way. I move kind of slow. I talk kind of slow. I let them know that I respect them.

The pictures that were coming from Vietnam were showing us what was really happening on the ground level. It was in contradiction to what our political and military leaders were telling us. They were straight forward documentary images. A powerful indictment of the war, of how cruel and unjust it was. When I finally decided what to do with my life, it was to follow in that tradition.

I became a photographer in order to be a war photographer, and a photographer involved in what I thought were critical social issues. From the very beginning this was my goal.

Photography can be perceived as the opposite of war.
