Magnum at the Sainsbury

After the 3rd swim of the week I trudged across the campus to the Sainsbury to see the Magnum show. It was the faces of sleeping soldiers in Afghanistan that touched me most. Not least cos their photographer Tim Hetherington was killed later in another war zone.
The Sainsbury, I think is always a good place for photo's, so rather than take a photo of a photo this was a display that I'm not sure of the connection to the exhibition, but I like the affect of layers of image. Can anybody tell me why the figure on the left is almost transparent ? to Fuji ?
