The Hotel Vierjahreszeiten in Maurach, Austria seemed like the perfect getaway for a group of friends on vacation in 1988. But before flying home, they decided to gather for a farewell party in the hotel restaurant.
In order to mark the occasion one of the party, Mr. Todd, set up his Canon film camera on a nearby table and pointed it at the group. (The table is the white band at the bottom of the photos.) After setting the self-timer on the camera he hurried back to the table. The shutter clicked and the film wound forward, but the flash did not fire. So Todd set the camera for a second shot. This time the flash fired.
The film was later developed, and it wasn't until one of party members was viewing the photos that it was noticed that the first (non-flash) photo showed a somewhat blurry extra head! (In the sequence above, the second (flash) photo is actually shown first for the sake of comparison.) No one recognized the ghostly woman, and they could not imagine how her image appeared in the picture.
The photo was examined by the photographic department of Leicester University, the Royal Photographic Society and the (SPR) Society for Psychical Research, all of which came to the same conclusion, the photo bombing ghost was not caused by a double exposure. Besides being a bit out of focus, the woman's head is also too large compared to the other vacationers, unless she is sitting closer to the camera, which would put her in the middle of the table.
