Sebastiao Salgado. Genesis

On a very fortuitous day in 1970, 26-year-old Sebastiаo Salgado held a camera for the first time. When he looked through the viewfinder, he experienced a revelation: suddenly life made sense. From that day onward—though it took years of hard work before he had the experience to earn his living as a photographer—the camera became his tool for interacting with the world.

Salgado, who “always preferred the chiaroscuro palette of black-and-white images,” shot very little color in his early career before giving it up completely.Raised on a farm in Brazil, Salgado possessed a deep love and respect for nature; he was also particularly sensitive to the ways in which human beings are affected by their often devastating socio-economic conditions.
