On the Pirates of the Caribbean ride in Disney World there's this scene with a skeleton steering a ship. it's quite dark but is occasionally illuminated a bit by a lightning effect. I've been trying for years to get a decent pic out of it, usually by timing it with the lighting, but it never works out quite right. not too long ago, Disney installed a "ride photo" spot just on the other side of the water that snaps a pic of your ride boat. This last trip I somehow got it timed exactly right, but was a bit startled by the results. Instead of providing some illumination, it looks like they turned on the lights! oh well, at least I now know what will happen.
