Maybe it is because Halloween is nearing, or maybe it was being reminded by Steven Colbert that crosses do not work on Muslim vampires, but I have been thinking a lot about vampires lately. It all started with a simple question. Is it possible to take a picture of a vampire?
Obviously, you could not do so with a 35mm SLR, as they use a mirror to project the image onto the film. In the old days you could use this technique to determine if someone was a vampire. Let's say your car broke down and you walked to the only castle around. You had suspicions about the aristocratic owner. You would simply take his picture, wait until you have finished the roll of film, send it off to be processed, and in a few days view the results. Of course, having waited a few days, you might have already joined the ranks of the undead.
Since you can view the picture instantly, digital cameras could make it far easier to test whether somebody is a vampire. Or would they? Since there is no mirror in the camera, would a vampire's image appear?
I have also wondered whether it is possible to kill a vampire with a stake made from recycled plastic lumber. It seems like a more environmentally friendly product than wood, and I would like to practice sustainable vampire population thinning.
