(Ought to be sub-titled is it 100ASA or not).
What do you do with the stuff to get the full 100ASA?
You can't stick it in with another 100ASA film like Shanghai or ERA, unless you drop the rating a stop.
Maybe Foma 100 doesn't like Rodinal, which is what I have been using exclusively so far.
I have had the same trouble using 120 roll Foma 100 with my Holga.
