I have got some konica negatives (Pro400 220) to be processed by my JOBO ATL-2300 soon. I have plenty of this Kodak Final Rinse chemical. My question is can I use it for the Konica films? Or is it strictly for Kodak's latest (such as Portra) films only? I understand that if I use a wrong final rinse (or stablizer) the nagatives will quickly develop a color shift. In addition, this has been a question for me for a while, is the Kodak C-41 Final Rinse chemical strictly for some latest Kodak negatives only? Am I correct to assume that it will not be for any Fuji negatives either? Thanks for coments from experts.
