Solargraphy is a unique form of photography that uses a solar camera to capture the movement of the sun across the sky. A solar camera is a simple device consisting of black and white photographic paper sealed inside a cylinder with a small hole punched in the side. These cameras are then placed in a secure location where they will remain undisturbed for days, weeks or even months.

According to experts, the ideal time period for shooting with a solar camera is from solstice to solstice. In the case of three solar cameras installed on the roof of The Weather Network in Oakville, ON, between June 21 and December 21, 2023, the cameras were painted black inside and out to minimize reflections. Placed facing south, these cameras are set to track the movement of the sun across the sky.

During the time the camera is mounted, sunlight passing through the pin hole creates a bright exposure line on the photographic paper whenever the Sun is shining. The movement of the Earth along its orbit causes the Sun’s path to shift approximately 1 degree each day, resulting in a unique exposure line that is traced across the image for each day captured by the camera.
