For just a few weeks in 2017, a garden shed appeared in the grounds of Ripon Cathedral. Only it wasn’t a garden shed. It was a camera obscura: a rather large pinhole camera.
Here was a wooden shed with a rotating angled mirror at the apex of the roof, projecting an image of the cathedral onto a horizontal surface inside.
Go inside, get used to the dark … and this is what you saw. A new perspective on an ancient cathedral.
