London, October 11 : The photograph that appeared to have captured the ghost of Doors legendary frontman Jim Morrison is not fake, researchers have claimed.

According to a new book, Ghosts Caught on Film 2: Photographs of the Unexplained, experts are yet to explain the photograph taken at the singer’s grave at the Père Lachaise cemetery in Paris.

Experts have apparently ruled out a trick of the light as probable explanation while image manipulation was said to be ''unlikely'', reports The Daily Express.

The book goes on to conclude that the image, clicked by travelling American rock historian Brett Meisner in 1997, remains unexplainable.

Meisner, who has since witnessed personal hell with a shattered marriage and death of a close friend from drug overdose, has decided to hunt a private organisation to donate the photo and its negative to. (ANI)
