In Asia, people very much want to have their picture taken. In India, I set up a piece of cloth as a backdrop, and people lined up to have their picture taken. They thought it was funny and interesting. In Europe and in Morocco, which was the last country I visited, people don't want to have their picture taken. In some countries, they feel it's like you're stealing something from them when you photograph them. When I'm in New York, I walk around with a camera around my neck all the time and shoot anything that catches my attention — people standing in line at [an] ATM or at Starbucks. You wouldn't do that in Cairo. In New York, I can take lots of photos as a "tourist," and no one thinks anything of it.
