This week for the blog I found another source for Sebastiao Salgado. It's a discussion on his work and it explains a lot about his photographs and what he's trying to evoke with them. One of my favorite quotes from this article is, "His photographs deliberately provoke and disrupt; they are not easy to look at because they are not supposed to be easy to look at."
