One of our investigators was taking pictures of the lanterns set out around the Fort. Careful to make sure no one would get in the shot, he made sure no one was around when shooting. There were not many people around yet as the tours hadn’t started. With 2 second timer and a 1/8 second shutter speed, it would have been impossible for anyone to get into the shot unnoticed. The funny thing is that the figure in the background wasn’t even noticed for 2 years.
