The four greatest photographers throughout the history of the world, there were only three. Those mentioned here are mostly technicians, yes they are or were god craftsmen but photogarphing a nice landscape and getting the exposure right is hardly a great milestone in human history, nor is it in photography. And photography is saturated with good photograpers taking beautiful pictures. However in order to be judged in a world class league aspiring to be among the three, then one must be invisible; for they were just that, and their invisibillity is reflected in their photographs. And in case you do not know who these men were they went by the names: Bresson, Capa and Salgado.
