@BlueSkyKing I have no idea what this even is. There is no way to say.

@Munumbis I have asked this many times and no one is willing. Clearly define what a ghost is and what attributes they have.

@BlueSkyKing No one knows. I have no idea what this is. Maybe a camera artifact. If it's movements didn't look so deliberate I would have just assumed thats what it was.

@Munumbis If the original medium was photographic film, then I'd suggest a slight flaw on that. Possibly a result of ageing before it was copied digitally.

It's intriguing, and I wonder if it's more common than we think.

@ArishMell I don't know, i haven't seen anything like it before. I've seen a few pictures of alleged ghosts caught in windows when a movie was being filmed but nothing like this.

@Munumbis It might even be a slight loss within the digital file.

I have had that in the past, though far more seriously, with images stored on magnetic discs. Those were damaged by an area of the picture replaced wholesale by a peculiar brown-purple patch.
