Magnum Photos
A photographers' cooperative founded in 1947 to let its members retain copyright and control over their own work.
In depth
Founded by Robert Capa, Henri Cartier-Bresson, George Rodger and David Seymour, Magnum's structural innovation was that photographers, not magazines, owned their negatives — which allowed them to choose assignments and pursue long personal projects. The model reshaped the economics of photojournalism and remains a reference point for photographers' rights.
Examples in practice
Retaining copyright allowed members to relicense a picture for decades rather than being paid once by a magazine.
