Cameras and the paranormal

[BaneOfGiygas]

What actually happens:

Captain takes a picture of vampire.
Captain silently lasers the vampire to death and gibs the corpse.
Captain feels like a big man now.

Pretty much. The thing is that, for a vampire/changeling/whatever test to be fairly balanced, the antagonist needs to know that it's taking place and it needs to be at a sufficient distance for the vampire to retaliate. Cameras fulfill neither of these two categories. Vampires already have the bible, holy water, and the entire chapel to worry about, and those are things that they can avoid given some effort.
