Famed photographer Henri Cartier-Bresson (1908-2004) is the subject of an expansive retrospective that opened yesterday at MoMA. His work in the 1930s "helped define the creative potential of modern photography" and made him one of the most influential photographers in history. As a photojournalist, he captured life on the run, exclusively using Leica 35mm rangefinder cameras—as the NY Times noted in their review: "By plane, train, bus, car, bicycle, rickshaw, horse and on foot, he covered the better part of five continents" throughout his career. The show will run through June 28th, and here's little look into the world he saw through his lens.
