Stick around, the cool part starts at 00:00:35.
I tried to manually bulb ramp, which is why the exposure bounces around in the beginning, and then I moved the camera later on. Would have loved to have a longer timelapse, but I pulled a total rookie move, and had my battery die on me at the end there. Would have loved another 30 minutes worth of photos.
Shot over Thanksgiving, 2013 from the top of a water tower.
