time lapse photography
I've always been fascinated by time lapse photography. Especially the sky. The atmosphere is so fluid. I recently found and purchased a camera made just for time lapse photography. It's completely weatherproof and can be programmed to take a picture as often as every 5 seconds or as slow as once a day. It's only 3 megapixels so the quality isn't that great. I've just started to play with it. This is the sunset the other evening, an hour compressed into 8 seconds.
