You've received a bit of criticism for dealing with people who earn their money in variously unethical ways. How do you resolve that in your own mind?

I just don't pay any attention to it, because it's a lie. The Telegraph published an article claiming that I'm the chosen photographer for African dictators but that's just not true. I don't go to countries where they'll shoot me. I don't care how much money they've got. I'm not going to Iran or Iraq or any of those places where they'll shoot me. Even Saudi Arabia is very closed. A royal family member has to approve my visa to get in and then I would be in a compound, they're not going to let me wander around. So that's all fine. Dubai and the United Emirates are just about as Westernised as you could possibly get. So that's all okay. But I wouldn't deal with some crazy dictator. I wouldn't do it.
