The Trouble with Reagent A3
Monobath A3 is something close to the reagent used in 55. While not yet as viscous, the pH, ratio of developer to solvent and hypo, and the processing times are converging. This is another 2 minute brew. You can see what we were concerned with in this intentionally underexposed negative shot of a black subject. TMY exposed at 400 off the surface of the blacker than 18% camera.
