Formula for bw film developing
I have concentrate, film developer no longer made...\\
I saved the label and apparently misplaced it, so need you help...
Product: Alta Zonal Pro Film Developer
Need copy of label or ratios for 35mm/120
Suggest processing temp, time etc.
I could guess, as I think most developers are similar, but some require more agitation and other s are none at all...exposed film is important enough to ask.
