receprocity?
I'm taking night shots on B with tripod and cable release of a building, for example, and exposure time has been no longer than five seconds on any shot. When the slide film comes back there is a faint, but noticeable upsidedown image of the building. Does this have something to do with receprocity and what does that mean exactly? Thanks.

Reciprocity error involves shifts in the film's color balance, and non-linear exposure times. It would not put ghost images on the film. I'd be interested in seeing your photo, but my guess is that the reflection is coming from a filter, shooting through a window, or lens flare.
