Tuesday on the NewsHour: Henri Cartier-Bresson

French photographer Henri Cartier-Bresson traveled the world for decades capturing people, places and history as a journalist, and in the process, helped define photography as an art form. His legacy is now on display in an exhibit called "'Henri Cartier-Bresson: The Modern Century'":http://www.moma.org/visit/calendar/exhibitions/968, a retrospective of 300 photographic works at New York's Museum of Modern Art.
