I finally finished my first time lapse video, with the help of the Internet and my friend's computer with Lightroom 3. It consists of 286 images, taken approximately every five minutes. My camera battery did die at one point, so there was a slight gap at one point. The video covers the time period from Feb. 9 at 11:53 p.m. to Feb. 11 at 12:11 a.m. I used my 10-22mm lens on a Canon 30D.
