I set up my tripod with my D200 mounted between my front seats, locking the shutter for 5 second intervals shooting at f/13 and ISO 400. I drove around Salt Lake City, capturing the lights of cars, streetlights, and signs around the city. I plan on doing this again with some sort of fisheye lens to capture a wider angle at some point. I think I’ll probably need to build a more stable mount for the camera as well, seeing how the tripod made slight movements in the resulting video pretty obvious.
Update: Jeff McGrath has provided me with a great shot of the rig I was using for this setup.
