I have stored slide and negative films for nearly 50 years at ambient conditions. Both the Fuji and Kodak products seem to have fared equally well except for E1 and E2 (the first) Ektachrome films.
I'm not aware that Kodak recommends cool storage for any processed film except for motion picture masters. At least, we never did when I worked on image stability there. So, Heinz, could you please give us a reference to that?
