Sebastiao Salgado. Genesis

"In Genesis, my camera allowed nature to speak to me. And it was my privilege to listen." -Sebastiao SalgadoOn a very fortuitous day in 1970, 26-year-old Sebastiao 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. Of the myriad works Salgado has produced in his acclaimed career, three long-term projects stand out: Workers (1993), documenting the vanishing way of life of manual laborers across the world; Migrations (2000), a tribute to mass migration driven by hunger, natural disasters, environmental degradation and demographic pressure; and this new opus, Genesis, the result of an epic eight-year expedition to rediscover the mountains, deserts and oceans, the animals and peoples that have so far escaped the imprint of modern society-the land and life of a still-pristine planet. "Some 46% of the planet is still as it was in the time of genesis," Salgado reminds us. "We must preserve what exists." The GENESIS project, along with the Salgados' Instituto Terra, are dedicated to showing the beauty of our planet, reversing the damage done to it, and preserving it for the future.
