Sebastião Salgado is one the most respected photojournalists working today, his reputation forged by decades of dedication and powerful black-and-white images of dispossessed and distressed people, taken in places where most wouldn''t dare to go. Although he has photographed throughout South America and around the globe, his work most heavily concentrates on Africa, where he has shot more than 40 reportage works over a period of 30 years.
