I’m not the most gregarious or outgoing person, so it’s a good thing that many teenagers like to have their picture taken. In fact, they will hunt me down and ask if I can get a shot of their group. I don’t pose them–they pose themselves, and they can be quite creative. I wait patiently then say, “OK, on 3! 1…2…3.” They don’t know it (or maybe they do), but I’ve already taken 2 or 3 pictures by the time I get to 3.
