Salt of the Earth focuses on photographer and explorer Sebastião Salgado’s latest work: discovering parts of the world still untouched by modern civilization. Salgado’s son, film-maker Juliano Salgado, co-directs with Wim Wenders and accompanies his father in the world’s most untouched places during the making of his new project, GENESIS. Juliano asks his father about his work which became a way of life... with the result that Sebastião was away from his family. Despite the tense and hesitant relationship between father and son, both gradually manage to rediscover the lost bond of their relationship. Together, they discover an ancestral state of nature, filled with mythical creatures and human communities isolated from the rest of the world. The film takes us to the heart of the Amazon into an Indian tribe, makes us travel to Wrangel Island in Siberia, shows us the Papoos of Irian Jaya and the luxuriant swamps of the Pantanal region in Brazil. Throughout this journey, Salgado the photographer is confronted by people of a completely alien background, finding his place among them. In Salt of the Earth, Wim Wenders focuses on his first passion and the basis of his work as a film-maker: Photography. His encounter with Sebastiao is the meeting of two men who have devoted their lives to images reflecting their view on the world.
