How 'bout checking the reciprocity correction for ``long''
(< 1/15-sec) exposures?  Sure, it'll vary from film to film
but I haven't seen anyone mention this yet. Still, it might
be a good idea to verify that you may or may not need to
increase the exposure or add a filter here and there. 

Then again, I've been out of photography for a while.
Please correct me if this is no longer needed with
the ``modern'' films.
