It doesn’t matter what kind of weather we have or how good or bad the light treats me, I like to photograph lighthouses. As you can imagine there are quite a few around Lake Superior and any time I had a chance a click was made. For me it is the fascination of the technical side that every lighthouse bares, combined with the fact that not even two are exactly alike. It is story telling about our heritage and a great chance to work with architecture, quite often embedded in a natural environment.
The bivalve fresnel lens of Split rock Lighthouse was built in Paris, France. While operating, the lens made one revolution every 20 seconds, floating on a thin layer of mercury. Light for the beacon was provided by a kerosene vapor lamp, which was replaced in 1940 by a 1000W electrical bulb. (source: Visitor Guide: Split Rock Lighthouse)
