Chris Macan’s solargraphs are exposed over a period of days or weeks.

The images are fascinating both for what they see as well as what they don’t. The ultra-long nature of the exposures allows them to record the movements of the sun as it traverses the sky each day, recording both its daily path as well as the change in its position in the sky over time.

The nature of long exposures also removes from the images many of the mundane irritants of daily life–traffic, people, and all the temporary things that clutter up our space simply vanish from the recorded image.

The resulting images often show vast empty spaces dominated by the mark of the sun on its daily journey across the sky.
