I just saw, for the second time in a while, an amazing film, "Salt of the Earth" about the life and works of photographer Sebastaio Salgado, a Brazilian social documentary photographer and photojournalist. His story is amazing and his photographer shows to me a master of texture, tone and of an incredible ability to capture the spirit of his subjects. If you can get to see the full-length film of his life and works I recommend it, but in the meantime here is a TED talk: https://www.ted.com/talks/sebastiao_...of_photography
