Simon Norfolk is one of my favorite contemporary photographers, I like the nuance in his work, the way he shows things that are not there. Take the example above, a first glance its just a staircase, but when you learn the story and contexts behind the image its true impact becomes apparent. This staircase is in a concentration camp in Auschwitz, Germany, leading what used to be a gas chamber and the worn down staircase shows the hundreds of thousands of people who walked up it to their deaths. The image below looks like a river of blood in the snow but is actually pollution from a factory. I think its a powerful metaphor for the fragile nature of our environment.
