"Shadowcatchers" at V&A

I was able to go again to this fascinating show before it closed. Back in November we went to a talk by Susan Derges and Garry Fabian Miller, which gave insight into their working processes, making photographs without cameras ... exposing sensitised paper to light and producing images that transcend what the camera can do.

Other photographers are Floris Neususs, whose "chair" is the first thing you saw; Pierre Cordier with his chemigrams; and Adam Fuss, whose work deals with time and energy rather than material form.
