For 40 years, the photographer Sebastiao Salgado has been travelling the continents. He has witnessed some of the major events of our recent history; international conflicts, starvation and exodus. He is now embarking on the discovery of pristine territories, of wild fauna and flora, and of grandiose landscapes as part of a photographic tribute to the planet's beauty. His life and work are revealed to us by his son, Juliano, who went with him during his last travels, and by beloved filmmaker Wim Wenders.
