Kodachrome After Jan. 2011

[LeoStehlik]

So, what happened to the guy in the Czech Republic that was processing Kodachrome?

Hi John, he would be quite happy to process stills (35mm slides) and/or teach me how to do it. However, I did not manage to convince him to consider processing cine Kodachrome film(s), which I can quite understand after being able to see the whole process...

Without revealing state secrets, how did he manage to get around the 14 steps necessary to process Kodachrome? I have been told by a number sources that it is impossible. I assume from your comment about cinefilm that processing is not a simple matter. Other than a curiosity why bother to process Kodachroem since there are alternatives for both cinefilm and still work. The only real need would be for those that have sound carts in the freezer. Not abig market most likely.

If I am not mistaken the complexity of Kodachrome is due to the colour dyes not being within the film. However, the information for the three colours must be within the normally processed film, even if it looks monochrome. So rather than add the colour chemically the solution will probably be to extract the three colour information and from it construct a digital image. As the colour dyes will not have corrupted the photographic grain the result could even be sharper than the original.

Good research project for post graduate digital imaging students?

Super8 Booster and I have been discussing this in the thread "K40 saviour" but the problem is that if you don't chemically distinguish the layers (using dyes) then you have to do it another way. Physically peel the layers apart? Well no, but that's the problem. The information is there in the BW processed emulsion, but if dyes are not used to distinguish the information in each layer then you need a substitute.

Its not so much a question of possibility vs impossibility, but practicality vs impracticality.

For example there is no reason why you could not use lasers to measure and construct a digital hologram of the emulsion, from which you could then digitally separate the layers and reconstruct a colour image.

This is certainly not impossible but the context in which this might be done is a question mark. In most contexts this would be impractical.

But one appropriate context is simply Art and Experiment.
