If Vampires don't show in mirrors is it possible to capture their image in a camera? Special film perhaps?
“It is not known what became of the photographer as only his camera and film were discovered close to the spot where this image was captured. A rare picture indeed, it now seems possible for some Vampires to be captured on film whilst others are not. In the same token some have mastered the ability to shape shift or control the elements. There is still much we cannot yet comprehend about these creatures of the night.”
Professor Arbronsius speaking at the Royal Geographical Society, London, May 22nd 1898.
