Sorry, but this is either doctored in photoshop and reprinted, or a spot on the negative. I have even seen this happen because a water dropplet gets on the photographic paper after exposure. When can we put orbs to rest? They are not evidence of ghosts. Dig a little deeper. Jumping to this conclusion rather than looking at more likely explanation does more harm to paranormal investigations than good. It becomes the boy who cried wolf. Real evidence gets lumped in with orbs and filtered evps.
