Default Transparency -- Lighthouse Fresnel Lens

This is an archive shot taken a year or so back at the Cape Meares lighthouse on the central Oregon coast. This is one of the few lighthouses that I've visited where you are actually allowed to go up inside the tower to see the big Fresnel lens. These things are huge! To help understand how these work, one section of the lens is removed to allow a view inside. This shot was taken through that removed section and looking out through the red section on the opposite side.

Very interesting Cal....are you up in the lighthouse when you took this shot as it looks as though you're at ground level.

I was standing on circular platform surrounding the lens inside the tower. The following photo shows an outside view. Note that this lighthouse is not very tall. It sits on a bluff about 200 ft above the water. This photo also is in keeping with the challenge subject since the lens we are discussing is inside the windows!

Thanks for posting the 2nd pic Cal. It certainly clarifies your position and how the image was taken.
