A History of the Sky in Time-Lapse Photography

From obeyken

Ken Murphy installed a camera on the roof of the Exploratorium museum in San Francisco and captured an image of the sky every 10 seconds for a year, resulting in a time-lapse study of the sky that reveals the patterns of light and weather over the course of a year.

Each day’s pictures resulted in about 6 minute of time-lapse movie. There are 365 movies in all pasted into a mosaic and all synchronized to show the same time of day. In this way, you can tell at a glance what the sky looked like at a particular time on every single day of the past year.

The rig consists of a Canon A520 digital camera with a wide-angle conversion lens attached, a Soekris net4801 computer running Ubuntu Linux, a 4GB CF memory card (emptied every couple of days), and controlled by gPhoto.
