360 Degree Time Lapse Movies

. July 9, 2011 . 0 Comments

Artist Ken Murphy has used a compact camera, a Canon firmware hack, and a motorized telescope mount to create, panoramic time-lapse movies.

Murphy shot two movies, one with a Canon A590 and the other with a Canon G12—both point-and-shoot compact cameras. He installed the CHDK (Canon Hack Development Kit) software on the cameras, amd programed them to take photographs every five seconds. The cameras were mounted on a panning telescope mount ($250) which slowly rotated the camera 360 degrees. A full rotation took 60 to 90 minutes.

“The camera (a Canon A590 with CHDK installed) snapped an image every five seconds while the motorized mount slowly rotated, making a single rotation in 90 minutes. I assembled the images into this panoramic movie, in which each “pane” is actually the same movie, slightly offset in time. The panes combine to make a single 360-degree view.”

“For this I used my new Canon G12, also running CHDK. I used the camera’s built-in neutral density filter and shot 2-second exposures at roughly 5-second intervals, as I wanted people and passing cars to blur out a bit. The camera made two full rotations in two hours.”

Murphy has also been working on his History of the Sky project, where an image of the sky is being captured every 10 seconds from a camera installed on the roof of the Exploratorium, on the edge of San Francisco Bay. More: http://www.murphlab.com/hsky/
