Room Obscuras 

Bringing the Outside In


We encourage you to black out a room and project an inverted image of the outside world onto your walls and ceilings by letting in light through a small hole in your blackout material.

The experience can be enjoyed by all, and the projected image can be photographed with a long exposure using a digital camera. This is a great opportunity to combine 21st century innovation and creativity with a 3000 year old technique.


For inspiration have a look at room projections by Abelardo Morell (the master at this sort of thing), the wonderful Marja Pirila, or Chris Fraser.

Materials required:

Cardboard from a large box
Gaffer tape, pins or bluetack for fixing card
Digital camera / phone which does time exposures. (optional)
