Hello, Pulled a roll of Kodachrome II K-12 from my new Argus C-3 today. I understand that I can process this as a black and white film only nowadays. Anything I should know before I just throw it into some HC-110? I don't need slides. Negs are fine. The camera itself is very sweet. In excellent condition with never-ready case, flash, cased Weston meter, and original box. And all for...FREE.
