Wim Wenders has a unique ability to use documentary as a window onto other artistic mediums, whether they be music (Buena Vista Social Club), dance (Pina), or, in his latest film, photography. Wenders co-directed The Salt of the Earth, a portrait of Brazilian photographer Sebastião Salgado, with Salgado’s son, Juliano Ribeiro. The film is both a comprehensive portrait of Salgado’s work and a meditation on the vocation of photojournalism.
