I've been hunting for the reciprocity chart for Efke PL50 and can't seem to find it. I've got a box I am going through and really like it but have not done any long exposures -yet.

I've also searched the AZO forum. No joy.

Thanks,
Ron

You'll find a recent discussion on reciprocity failure here http://www.apug.org/forums/forum37/60348-comparative-reciprocity-failure-available-sheet-films.html#post772490
With the support of the there mentioned documents you won't have any problems to figure out the correction factors for any film yourself.
