Here is the video I was talking about the other day. Just a quick note on how it was done: I set my camera on a tripod on my balcony and set it to fully manual exposure(you don't want the exposure suddenly changing in the middle of your movie) and fully manual focus (obviously enough you don't want the focus to change half-way through either). I also used a small aperture and a ND Filter to give a long-ish shutter speed. A long shutter speed is preferable because you want a little bit of motion blur in your shots, so that they will blend together a bit when you combine them. Then I connected the camera to my laptop via USB, and using Nikon's Camera Control Pro in timelapse mode, I set it to take one picture every ten seconds. I left it run until the battery in my camera died, and it took 1700 pictures.
When I had all the photos, I imported them into Lightroom, made some small adjustments, and synched all the photos up so that they looked the same. I then used a piece of software called VideoMach to put them all together, at thirty frames per second, which gives a smooth video. That's about it!
