Karl den Hartigh sent us a ghost picture taken with a mobile phone. He calls it "ghost between two girls."
It was sent to us embedded in a PDF, meaning that we could not analyze the actual photograph image file. Also, it was already enlarged, cropped and pixellated from iimage compression.
Inconclusive - without the original image file, we are unable to verify authenticity. Also, the pixellation caused loss of image quality. Still, it's a fascinating photo and worthy of your examination.
