Toronto. George Dunbar sent me a Flicker link to people jumping. Use the big sideways arrows (< and >) to go from picture to picture.
When George mentioned the topic, I immediately thought about Leica photographer, Henri Cartier-Bresson, and his famous Decisive Moment print of a man jumping a puddle.
Any of you who have studied physics will know that an object stops and reverses direction at the apex of its motion. The cameras and lenses of the day demanded such timing to ensure the subject would be at its sharpest.
