Left is amidol, right is 510 pyro. Pretty interesting to see the tone produced by the pyro. It adds that same stain to film as well. Pretty nice imo!

Very hard to see through a phone pic, but the amidol produces a noticeably blacker black than the pyro. That increased dmax is what amidol is all about. Even with a shorter exposure the tones are richer on the amidol print.
