Same camera, same lens. I thought that maybe the lens shutter might
have been slightly off since it hadn't been used for a while, but
many of the exposures were made using the B setting and a watch, and
were several seconds long. Also usually if a shutter is sticky, it
overexposes rather than under exposes.
On an vaguely-related note, a friend of mine pointed out that the
reciprosity effect can vary widely between different films.
Case in point; though Kodak's Tri-X is obviously a higher-speed film
than Fuji Acros, once you get out to multi-minute exposures, you find
that Acros actually requires less exposure, thus making it a 'faster'
film.
