Ephemeral Art and Science: The Solargraph Camera Tells Unseen Stories of the Sun’s Movement

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

The solargraph camera is a fascinating device that combines art, science, and unpredictability. It consists of a piece of black and white photographic paper sealed inside a cylinder with a tiny pin hole drilled into the side. The camera is then placed in a secure location where it will remain undisturbed for days, weeks, or even months at a time.

Three solargraph cameras were set up on the roof of The Weather Network in Oakville, ON, between June 21 and December 21, 2023. Painted both inside and out in black to reduce reflections, the cameras were positioned facing south to track the Sun’s movement across the sky. Experts suggest leaving the camera from solstice to solstice as the optimal timeframe for capturing images.

While in place, sunlight passes through the pin hole to create a line of exposure on the photographic paper whenever the Sun is shining. The Earth’s movement along its orbit causes the Sun’s path to shift approximately 1 degree each day, resulting in a distinct line of exposure added to the image daily except when clouds block the sky. Weather conditions like overcast or partly cloudy days will affect the appearance of
