Long Exposure of a Lighthouse

Once per year at the Pigeon Point Lighthouse they shut down the weak insipid modern aerobeacon light and switch over to the 1kilowatt lamp (which replaced the older oil-burning lamps) and fresnel lens of the original, restoring its appearance to what it was 135 years ago.

Capturing a shot like this is tricky because the lens itself actually rotates, which looks great but is tough for long exposures. But for the first 5 minutes they leave it static to indulge all of the photographers who turn out and want this shot (this highly unique and one-of-a-kind shot of course).
