Magnum

"Magnum is a community of thought, a shared human quality, a curiosity about
what is going on in the world, a respect for what is going on and a desire to
transcribe it visually." -Henri Cartier-Bresson

Most important for enabling photographers to pursue their personal work while also working on assignment and issuing control and ownership over their own images. Magnum is a co-op of some of the greatest photographers since it's inception in 1947.
