Mt. Nebo Sunset via Time Lapse Photography

I've seen some very interesting time lapse projects online recently, so I thought I'd try my hand at one today. I drove up to Mt. Nebo State Park in order to photograph the sunset. When I got there, the wind was blowing hard and the clouds were moving in, which are perfect conditions for a time lapse photo. The movie below was created from 740 individual pictures taken over a 50 minute period just before dusk. I took about one picture every two seconds and composed this movie with Quicktime Pro. The trick to doing these right is putting your camera on manual and adjusting the exposure and shutter speed to get the effect you want. Dragging the shutter works best if you can do this. I set my initial exposure too fast and was stuck with this for almost an hour. You need to think about what that first exposure should be in order to get the best end results. Next time, I'll set my exposure a little slower than what I did for this (1/20 sec @ f22).
