Capturing the Sun’s Path: Exploring the Art, Science, and Chaos of Solargraphy

A solargraph camera is a type of camera that uses black and white photographic paper sealed in a cylinder with a tiny pin hole drilled into the side. These cameras are left undisturbed in a secure location for days, weeks, or even months to capture unique images of the Sun’s movement across the sky. The duration for which the camera is left to record is at the discretion of the photographer. Experts suggest that the ideal period of time for a solargraph camera to record is from solstice to solstice.

Three solargraph cameras were installed on The Weather Network’s roof in Oakville, ON, between June 21 and December 21, 2023. To minimize reflections, these cameras were painted black inside and out. Positioned facing south, they were set up to track the Sun’s movement across the sky. It’s important to note that leaving solargraph cameras in public places may result in theft or damage, so careful selection of location is crucial.

Sunlight passing through the pin hole creates a bright line of exposure on the photographic paper whenever the Sun is shining. The Earth’s motion along its orbit causes the Sun’s path to shift by approximately 1 degree each day, resulting in a unique line of exposure being traced across each image recorded by
