Would it be possible to develop regular chromogenic slide film in similar way as Kodachrome was?
Maybe I am wrong, and haven't sufficient knowledge about the structure of real Kodachrome film, so sorry in advance if my idea is stupid from the start ( ;
As I know, Kodachrome was basically three-layer (I mean light-sensitive layers) film with spectral response for R, G and B light, like regular chromogenic film is.
It didn't contain any colour couplers, since the respective dyes were delivered into their respective layers during the elaborate process.
The chromogenic film like Ektachrome indeed contains colour couplers, but they are clear in their initial state and get coloured only in reation with color developing agent. In kodachrome process there is no CD agent to react with, so these couplers should remain invisible.
Maybe there would be a problem with different diffusion characteristics of the emulsion of chromogenic film - it is designed to be highly penetrable, so that developer can get in action in all the layers immediately, but in Kodachrome process there are more developers and they have to be selective, so the layers had maybe deliberately designed with different penetrability...
It's clear to me that main problem is to get K-14 process working rather than to get some old Kodachrome film for experiments. But I am just curious if it would be possible to "bend" the regular film to behave as Kodachrome, though with some modifications of the original K-14 process.
