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

Solargraphy is a unique and captivating form of photography that combines art, science, and unpredictability. This type of camera 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.

Experts recommend leaving the camera from solstice to solstice to capture the optimal amount of 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.

While the camera is 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
