It's a damp day in Paris behind a station. A man jumps over the wet sidewalk. From this ordinary scene, one man makes an iconic photo. This is picture taken by the French street photographer Henri Cartier-Bresson. This is one of his best known street photographs. . The reflection of the man almost, but doesn't touch him, making him seem to fly above. His motion seems to echo the figures on the billboard. I think that this photo shows the decisive moment, which he is known for. Any earlier or later, and it would have been ruined. But it wasn't, turning this ordinary scene into an enduring artwork from a true master of the decisive moment.
