PYROCAT-MC GLYCOL: Alternative Process Film Development
I noticed that Sandy King is offering his new formula(s) of both Pyrocat-MC Glycol and Pyrocat-HD Glycol through Photographers' Formulary. I am interested in their staining properties contrasted to pyro for alternative printing.
What are the primary differences between the two formulas? (Speed; Compensation/Expansion; Sharpness; Etc) When would one formula have preference over the other developer variant or are each very similar?
I find the organic solvent approach very intriguing and practical for consideration. I primarily work with HP5 Plus; Bergger BPF 200; Acros 100; films. Most frequently use the Farber's shared, Pyro- triethanolamine formula.
