I have just learned that hard way that it is NOT a good subsititute for dry vermouth.... Seriously though.... This is the stuff provided by the UofA for free in the developing room. I have nothing against it, except that it is rarely mentioned much when it comes to developing times. I ended up with some Arista.edu and was unable to come up with a decent developing time for it in the "literature" out there. Which was fine, I have a big jug of D-76 that I used, but hey, if the free stuff can work, I'll save the D-76 for my ortho work. So, what "IS" Ilfosol? And by that I mean, what common developer can I just compare it to and still get away with something printable when in doubt?
