Yep, he really is very good. And a stunning printer to boot (if he prints his own stuff, I'm just assuming). Some people even accuse him of beautifying suffering because his pictures are so good, though I think that's a bit naive personally.
Check out Marcus Bleasdale if you haven't already. Very similar to Salgado in a lot of ways, though maybe not quite the finesse.
Random fact of the day: Both used to be bankers (Salgado an economist for the World Bank, and Bleasdale a London Broker) before realising they were wasting their lives and needed to do something more useful. There's hope yet.
