Under the Sea
Okay, not really. Open lens experimentation, pointing at the movie screen in the Living Seas attraction of Epcot, while it was displaying the strobe pulse of a lamp from a submarine.... before they redid the whole thing from being serious to kid-friendly by using the "Finding Nemo" intellectual property.
I don't have insight on how I managed this picture given how it came out. I *think* that what happened was that the camera failed to advance the frame, and the frame was exposed with nothing such as when a picture is taken accidentally while the camera is still in a bag. Thus, I think this is a double-exposure frame, where the first picture was completely dark. All on accident since I cannot control when the LC-A filmstrip advance mechanism chooses to cooperate or not.
