Following the discussion about who would like to see Panatomic-X return, and realizing that Plus-X has also been discontinued, and also the comment that, with changes in the production facilities, Kodak would not make the same Panatomic-X anyway, I wondered about a new film. Some of the reason for asking about the return of a film, is remembering the film with that name, even if the new film isn't the same. But anyway, how would people feel about a new film, somewhere between Panatomic-X and Plus-X, but otherwise using similar technology, and so hopefully similar images. I am not sure that you can take two film recipes, combine them together, and get a new film with properties in between, but maybe. So, maybe a new ISO 64 film instead? Or 50 and directly compete with Pan F+? Thinking about it, completely new films seem to be pretty rare, though sometimes they are new, with an old name. Is Kodachrome 200 completely different from Kodachrome 64, or just a slight difference? From: Ilford History and Chronology Ilford FP goes back to 1934. Then a series through FP2 and FP3 into FP4. Are those part of a continuous small improvement series, or completely new films with similar names? If there are enough users of cubic grain films for Kodak to produce a new (or improve an old one), what should it be like? It does seem that an ISO 64 film might be about right.
