Trick Of The Light Or…
This trio of young ladies was out for an evening of fun and enjoyment. They took it in turns to be the cameraperson, swapping back and forth, producing plenty of pictures, all of them different combinations of pairs in different locations.
It was not until later when they viewed their images, did they see this creepy fourth person gripping the arm of one of the friends. Usually, these photos are the result of trying to use the timer and being caught mid-sprint into the frame.
However, not only did these three not try using a timer, they didn’t have a tripod or other suitable surface to hold the camera if they wanted to.
Add to this the fact that the strange blur clearly has a very muscular set of shoulders and you are left with a mystery.
