Description

A solargraphy camera is a type of pinhole camera that is used to capture long-term exposures of the sun's path across the sky. The camera typically consists of a light-tight box or container, with one small aperture (or pinhole) that acts as the lens. The film is placed inside the box, and the box is pointed in a fixed direction towards the sun. The camera is then left in place for an extended period of time, typically several months, to capture the sun's apparent movement across the sky. The resulting image is a time-exposure photograph that shows the sun's path as a curved or arched line.

As you can see in this image, the sun's position varies greatly between the winter and summer months in Norway, with it appearing much lower in the sky during the winter and much higher in the summer. Unfortunately there's some water damage, but I think it adds some charm.

Exposure time: 9490 hours (almost 13 months)
Equipment: Beer can, ILFORD Photographic Paper, a needle & lots of tape
