I came across this work in the BJP. The disruption to the images reminded me of the Nick Knight images I saw at PhotoLondon. I still don’t know how Nick Knight altered his images but these were changed using a method called Data Bending. They are also aesthetically similar to the skin images by Rosanna Jones above, but using a completely different method/medium.
