New York Times photographer Vincent Laforet takes these amazing shots of New York City from helicopters--an exciting but tricky task. The helicopter's skids and rotors are unpredictable and can get in the way of good shots, he says: "Sometimes everything is moving so fast, you can't really see what you're shooting, and you just hope you get one good frame in there." And don't overestimate the helicopter's stability. Laforet's advice? "Never lean out in the wind."
