I find the compensation times for Foma and Arista films pretty interesting. A 10 sec exposure compensated for reciprocity failure, jumps to 1:02 with Fomapan whereas only between 15-30 secs for all other films.
Makes me wonder what's so different about Fomapan that reciprocity is that far off.
I once shot a 2 hour exposure with FOMA and got no image because apparently it should have been 6 hours... Any other film would have been over exposed at 2 hours lol
get yourself a exposure guide
works like a charm, every time
then it is the internal light meter
Just saw this thread - one other reference about night exposures, per AA - if the moon is in the image, the exposure for it would be the same as sunny daylight for the given film, as this is the illumination it is getting.
