Expired Agfacolor CNS in C41

I had a Agfacolor CNS 120mm film in my fridge, today I decide to take out and load it in my camera, the film is normaly ISO 80 but I rated my light meter @ ISO 60 because it is very old expired film from 1981.


Agfacolor CNS color negative film is another develop process than new color negative film. I think it was C-22 Process, it is at lower temperature then C41. because the emulsion of de Agfacolor cns will melt if you develop it in 38C° C41 chemicals.

So i give it a try, and did a stand development in C41 chemicals.

This is what I did:

Pre soak film in 20C° water for 5 min.

Put it in C41 color developer for 50 minutes in 20C° agitating every 10 minutes.

Put in in C41 Blix for 8 minutes in 20C°, agatiting almost continues.

wash in water 20C° for 5 minutes

Stabilizer for 1 minute 20C°

And let it dry!

I scanned the negatives with a Epson V500 scanner and let the scanner do some color corrections.

These are some results:

    I know it’s an old post but thank you for this. I’m about to soup some Agfacolor CNS (expired in 1973) in C-41. I’ll let you know how it comes out.

    Thanks for this! I have two rolls of CNS in Rapid format to play with. I think I’ll shoot them at ISO 20-ish.
