I agree about the images used in the Credo link, they are really hard to look at.
I attended a conference where David Burnett spoke and showed his work and had a coffee with him and a few others after - he's a great photographer and speaker. I love some of his images.
Looking at his website and other images he took at Sochi - there are some really good / interesting images in there although I assume that those were not taken with the Credo.. or else why not show those.
