I can't recommend enough watching the The Salt of the Earth[0] documentary. It's not only an impactful review of Salgado's career but also a great (and visual) way to expand our knowledge about the world and its recent history.
I also found the scenes, where you can see Salgado's face close-up and frontal while he looks at his photos, very strong. I read somewhere the scenes were filmed through a teleprompter which is an interesting artistic technique.
