I'm trying to make sense of this and am failing miserably.  I'm
wondering what kind of energy could be stored on one side of the slide
that was not transferred to the other.  Could the slide have been used
as a capacitor?  What kind of energy could it store that would fog IR
film?

I've used old Riteway holders for quite some time now and have not found
any problems with fogging.
