Crown of Bodie Lighthouse
The Bodie Lighthouse contains a first-order Fresnel lens. The lens is about 12 feet tall. Unlike many other light houses, the lens in this lighthouse does not rotate. The dark lanes are the window frames. Instead of rotating the light is a 1000 Watt bulb that is dark for 22.5 seconds, turns on for 5, off for 5 then on again for 5 seconds. The 22.5 seconds of darkness makes it possible to get an image that does not "wash out" a shot if you time the shot to start just as the last on-cycle is ending... of course that's what we did.
Our first trip to the lighthouse had enough moisture in the air that capturing the "beams" proved an interesting challenge.
