Actually the key is that it specified ECN-2 processing. The main difference between that and C-41 is there is a step before the first developer which is IIRC a hi PH bath to remove the anti halation layer. Once the layer is off C-41 will produce a printable image. If you are going to try home processing I would go to your local pet store and get a bottle of the chemical to raise PH in aquariums and a PH tester, mix the chemical in water to produce a mixture of PH 11 or greater and use that for the first bath with a quick water rinse after before the developer. The old Extachrome movie films processed in chemistry nearly identical to their still cousins, but this is a totally different type of film.

Because one kind of film has some extra 'anti-halation' layer it does not follow that another will. I've used 35mm movie film in still cameras many times in the past without trouble. Some, Kodak release positive (B&W) for example, has no anti-halation backing at all. BUTCH Each man had only one genuine vocation - to find the way to himself. Hermann Hess (Damien)
