I picked up a few 120mm rolls of the Kodak Ektacolor 400 Pro Gold. Date is 2000 and no idea how they have been stored. The oldest roll I ever developed was in a second hand camera I found and still had some pictures from the late 70-ies on them They came out quite grainy, I just developed as per standard procedures with the Tetenal C-41 kit and followed the Tetenal Kit developing times. Now, is there anything I need to do different when I shoot this roll of Kodak Ektacolor 400? Do some EI correction perhaps or just boxspeed? And with development, do I prewash? (actually I never prewash color, I don't do that much C-41, not no if needed) and just follow standard development times with the Tetenal Kit, or adjust any of the times cause this is an older film. Thanks for the help.
