This footage was filmed inside my camera obscura, whilst it was set up inside St Anne's Arts and Community Centre.
The video was made as a way of testing the quality of filming in the low light levels within the obscura, and getting a feel for what works well. The light from the window is projected onto a circular reflector. The image is produced by a 4 inch telescope lens, with a focal length of 1m.
