Snow Time Lapse

I decided to attempt a time lapse of our Latest snow storm. I put my D300 on a tripod and used the interval timer to take a shot every 30 seconds. The video came out pretty good. I would have liked to have made it longer with more frames, but I ran out of batteries. I used manual focus and auto exposure. I would have liked to have locked the exposure, but it would have been way off when the sun rose.
