Antiquarian Skylight

Author: Guest Writer/Sunday, January 22, 2012/Categories: Uncategorized

Exposing a piece of film over a long period of time, from a specific location, compresses the exposure, and creates a solargraph. The photographic technique requires a pinhole camera to capture the diffuse and thin light onto photo-sensitive paper or film.

Pinhole photography is an early light capturing approach now being used to create modern art photos. The images look like they might have been discovered in an old trunk filled 19th Century daguerreotypes of  soldiers or cold winter forests. A pinhole camera is required to make a solargraph. A photo can be produced using almost any container that allows a spot of light inside to slowly expose the film. The exposure time depends on the size of the pinhole.

A beautiful and unconventional solstice solargraph was recorded with a pinehole camera made from a soda pop can lined with photo-sensitive paper. The photograph required a 6-month long time period to properly capture the image of the suns passage across the sky. The camera was positioned at a stationary location, near the radio telescope of the University of Hertfordshire in the UK, where the simple camera continuously recorded the Sun's path each day from June 21st until December 21st, the dual summer and winter solstices. The ancient, foggy, appearance of the image was caused by cloud cover while the clear lines recorded the suns tracks through the sky over the 6-month period.

Combining art with science can produce some amazing results as this antiquarian skylight shows. Go out and make your own soda pop can pinhole camera and create a solargraph!
