Room Obscuras - Bringing the Outside In


To go alongside the solargraphy project 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) and the wonderful Marja Pirila  

Materials required:

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

Justin Quinnell shows you how to make a Room Obscura using found materials.

More detailed video by Di Stoppard from the Whangarei Camera Obscura New Zealand. Be aware the window used in the northern hemisphere should face North.
