Miha, you might notice there's a rather large difference in tonality between the example I posted and thise earlier in the thread. Foma films are rather contrasty and they tend to build this up rather quickly so you need to make sure the negatives aren't over-developed.

I did some simple Zone system tests when I began using foma films and later some reciprocity tests, i foindthe films far better than Foma themselves suggest.
