Hi, now that Agfa have gone belly up, have swapped to Tetenal C-41 chems. Problem- their time for the blix is 4mins, my Jobo time is set and not reprogramable at 8mins. I realise the blix stage is supposed to go to completion, but will there be an adverse effect in doubling the recommended time? Tetenal instructions say a 50% increase is O.K. but what about a 100% increase. Anyones comments would be appreciated before I commit film to chemicals.
