Solargraphy: I spent yesterday in Bath visiting a conference on Astronomy, Culture and Art. I had the pleasure of seeing many beautiful presentations and I was completely blown away by the genius solargraphy of Tarja Trygg. With little tiny pinhole cameras and epically long exposures, she has collected (along with her ‘can assistants’ of which I hope to become one) images from all around the world mapping the movement of the sun over days and months. The results are so so tactile and fascinating. This is a picture from Stockholm following the months just after the winter solstice. It’s quite haunting to finally see so clearly the tracked gradual movement that you are so achingly aware of when you live in the north.
