When you are doing portraits, you have that intimacy with someone for a few minutes. For a really good portrait, you don't take the portrait - it's given.

I remember, on the medevac helicopter, I said to myself, "I am not f - - g dying in Afghanistan." People talk about having flashbacks; I began having flash-forwards. I began thinking of all the things I still wanted to do.

A lot of great creativity comes from restrictions.

For me, documentary photography has always come with great responsibility. Not just to tell the story honestly and with empathy, but also to make sure the right people hear it. When you photograph somebody who is in pain or discomfort, they trust you to make sure the images will act as their advocate.

I had been a fashion photographer for over ten years, but I'd always been dissatisfied with what I was doing. It was all about selling people, and I got disheartened by the whole industry.

It is what it is. I can't change what's happened to me.

I'm not a war photographer. I've always dealt with the consequences of conflict.
