Some of the old time pictorialists, ie Enos, Desme, Cummings, said the Pot
Bichromate was slower tham Ammonium but had a longer straight line. I dont
know about the straight line response, maybe there is no difference, but my
experience says that Ammonium is faster and I see no difference between the
results so that is what I use.
