By "Pyro" it is meant the PMK or ABC or D1 Pyro we normally think of and is a big rage among in the know large format photographers. Pyrocatechin was in Neofin Blue and at one time in HC-110 and although a high contrast developing agent was of course used for just the opposite. I guess it also has very high Acutance.
