PYROCAT-MC GLYCOL: Alternative Process Film Development

[Mark Booth <boothm@mac.com>]

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.

Thank you,
Mark
