I think this is incorrect as well. Since the OTF also works with the
reflections from the film plane, the meter would be unable to see the
reflections of the vampire in which case it would yield overexposure.
The amount of overexposure is determined by the illumination of the
background of the vampire.
To avoid all these complications, make a manual exposure with a manual
flash (no fill in, no ttl, etc.) You can do this with all OM cameras
anyway.
