Here is a timelapse of clouds I created this weekend. I used a 2 second interval and let the camera run for a little over 2 hours. This timelapse plays back the clips at 24fps, and I think the slow dreamy feel looks pretty good (30fps would just speed it up).
I used Lightroom to make the colors more intense. And thanks to Bob for sharing a better way to import a large photo sequence into Premiere Elements!
