    Did you ask if Dwayne's could process it?

    They don't. It can only be processed as B&W at this point, unless you're able to set up a K-14 hand line.

    One has to wonder why Dwayne's doesn't set up a line to process 120, like, twice a year or something and charge a lot of money for it. They could probably get a few people to pay $25 a roll for the service, which is what salvage processing usually goes for with obsolete processes.

    Unless you do it by hand. The formulas are published, and it can be done.

    I'm pretty ambitious with a lot of things, though unless you want to personally give me a hand...
    I think I'll have to pass on that for now.
    Maybe next year.

    I've seen it done by hand.

    Other than the difficulty and expense in getting the couplers and mixing and a long process it isn't too hard.

    If you really want it, you will do it.

    Dwaynes is the last Kodak authorized k-14 lab. That doesn't preclude unauthorized labs from doing it. If I'm not mistaken, there is also a Japanese lab that still does k-14.

    I'd be very interest to see the formulas - are they somewhere on Kodak's website?

    Thanks,

    Matt.

    They are in the patent. It has been mentioned in this forum several times as has hand processing. I don't have the number handy. I think that one of the threads was titled "Kodachrome secrets".

    FYI I checked Rocky Mountain Film Lab, who specialize in discontinued film types, and even they won't do it (except as black & white). They might have more information about someone who does though: http://www.rockymountainfilm.com/k14.htm.

    Assuming one was to try to do it themselves, theoretically you could use and older process like K-12, right?

    No. That would be like using C-22 for C-41 film or RA for EP-3 paper.

    PE,

    Do you know how Koadachrome sheet film was reexposed to light? I can see how it could be easily done on a roller transport machine for roll film, but I think it would be much more difficult for sheet film.

    From the cleat marks I've seen on Kodachrome sheet film it looks like it was done on hangers just like a dip and dunk E6 line.

    We did sheets and strips on hangers and exposed easily with a red light to the back and a blue light to the front. We used wratten filters.

    As long as the film is flat there will be no problem. The light should be directed to just one face and perpendicular to the film. It can be moved up and down a length of 35mm but not horizontally or you can get light around the edges.

    It isn't that hard. Once you calibrate your light, it works fine. How do you think we processed small batches of experimental coatings, or how did we do small batches of experimental developers. By hand with hangers.
