This photo was taken by 19-year-old Adam Harris during a ghost tour of Barwon Park Mansion in Winchelsea, Victoria, Australia. According to witnesses, a member of the group with a digital thermometer detected an unusual heat source in a corner of the building where another patron had sensed a presence. Harris claims to have snapped several pictures in the same area before his camera mysteriously stopped working. When the group got back outside, Adam says his camera turned back on and he discovered this ghostly image of a girl. Experts remain baffled. Video and additional details at Today Tonight on Yahoo!7.
