Solargraphy: An Art, Science, and Unpredictability Combination for Remarkable Photography

Solargraphy is a unique form of photography that combines art, science, and unpredictability. It involves placing a camera with a piece of black and white photographic paper inside a cylinder with a tiny pin hole drilled into the side. The camera is then left undisturbed in a secure location for days, weeks, or even months at a time to capture the Sun’s movement across the sky.

Experts recommend leaving the camera from solstice to solstice as the optimal timeframe for capturing images. 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.

As sunlight passes through the pin hole, it creates a line of exposure on the photographic paper whenever the Sun is shining. 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 these lines on paper.

In addition to capturing daily movements of
