Camera Interval Timer
The camera shutter operating system described here makes it possible to take photos at a predefined interval, or to trigger two cameras together for stereoscopic shots. This device makes it possible, for example, to take a series of photos every 30 minutes of a flower as it opens, a baby bird hatching, etc. so as to include them in a video. The system was originally designed for a Canon EOS camera, but it can readily be adapted for other cameras that are able to be remote controlled.
