I usually develop my cheap C41 200 ISO films (from http://poundland.co.uk) films in B&W chemistry (Promicrol) at 20 degrees for 12 minutes.

If I meter for 400 or even 800 ISO (so I can pretend to be Garry Winogrand) how would you recommend push processing to compensate?

The film is AGFA VistaPlus 200, if that makes any difference.

  • \$\begingroup\$ Interesting question. Leads to what you expect to do with the negatives. Quality ingredients are not a guarantee of first class product, but there is only so much you can do with clearly inferior ones. \$\endgroup\$ Commented Nov 19, 2017 at 18:10

1 Answer 1


From my experience: + 1 stop multiply normal time in seconds X 1.15 +2 stops multiply normal time in seconds X 1.9 Best you test and find multiplying factor for your chemicals. Best of luck. P.S. Likely no need to push process for 1 stop.
