    A very interesting idea... If you can come up with a proof of concept image, i'd be fascinated to see it.

    You don't need an ICC profile for Kodachrome, as long as you can get some separation, you can get full separation using channel mixer, and then a good colour balance using colour balance tool and levels.

    >>And most importantly how can we scan for example back layer without seeing others or 3 scans

    Therein lies the problem.

    The general optical scanner cannot scan three layers of the film and tells the differences of three layers and based on this information to manipulate the image.

    May be it is possible to develop one layer at a time using different chemicals or processes.

    This requires take three pictures for the same image every time. Each picture will be used to develop one layer.

    The Kodachrome process was very complicated, the film consisted of many layers. The color development portion of the process consisted of three separate color development steps. The film did not contain any color couplers. Each of the three couplers was in a separate color developer. It is incorrect to think of the Kodachrome process as a black and white process. There are several sites on the web that explain the process.

    While it is theoretically possible to retain color information using only BW developers, most of the Kodachrome process would still have to be used. The film would have to be re-exposed three times and developed three times. This is something that is no longer possible since the last machine that could do this is now gone. Not only that but there seems no way to obtain the color information from such a BW positive without being able to scan each of the three layers containing a BW positive seperately. No scanner at present can do this. You would need a cross between a scanner and a microscope.

    The coup de grace is that no one is making this film anymore. The coating machines for it are long gone.

    The sad part is that Dwayne's tried to GIVE AWAY the machine, but no one, not even any museums would take it because it was just too big (it was I was there at the lab on the last day). I took pictures of the machine ON Kodachrome then developed them in said machine, what a trip!

    Anyway, man I hope someone can find a way, I miss Kodachrome so badly.
