Time-lapse of frontal cloud cover arriving
Below 18 second .avi movie was made with my Canon Digital Ixus 400 hooked up to my lap-top, which thus controlled its operation. 181 pictures were taken over a timespan of 1.5 hours (so: one each 0.5 minute).
The attempt initially was to capture the clour-play of sunset on the high altitude cirrus clouds. But right after I started the series, a frontal low cloud cover came in.
