I have 48 rolls of this 120 film. Ten years old. I can't justify the expense and hassle of E6 processing for expired film. What would happen if I were to develop this in B&W developer? Anything? Any other ideas on what to do with it?
Cross processing in C41 is always an option. This is quite popular with the lomography (Holga and Diana) shooters out there. Results seem to vary widely, though I imagine that's the point.
I don't know what the outcome with BW processes would be.
