Q: Where are you?

A: I’m back in London. I got back Sunday from northern Nigeria, and before that I was in Yemen. Then I was in New York, and then I went to the border of Texas and Mexico for that 24 Hours series for The Times. And then Saturday I leave for a book tour .

Q: Why another book?

A: Well, this is a photo book. I didn’t anticipate writing a book [“It’s What I Do”] before doing my first photo book, but that’s how it worked out .

I’ve always wanted to do a photo book, but I got sidetracked when I started that process in 2011 after Libya. When Tim [Hetherington] and Chris [Hondros] were killed, I didn’t feel like looking at these photographs. So I ended up writing.
