Henri Cartier Bresson was a French photographer whose career began in the 1930s. Much of his work during that early part of his career was characterized by the authenticity of his photos. He used a 50mm lens which provided him with the utmost anonymity so that his subjects would act normal as they would not be aware of him being a photographer. Bresson was later assigned by Magnum Photos to work in many different parts of the world, still using his same street photography techniques.
