    Yes Fred, both used RDRs (Redox Dye Releasers) with an ETA in the pod to facilitate dye release. It used Reversal F emulsions to get an ISO of about 100 (? - I've forgotten the speed). A 3000 speed counterpart with metallized dyes was under development. It used negative emulsions and got very high speed via some interesting technology. The dyes were very stable.

    I've always loved the story about the core and shell Reversal F emulsion being created as a spy film during WW2. The latent image went internal and the common surface developers of the day would not develop the image; it took a grain cracking developer to do this.

    So you'd want film-pack. Oops. But large format aero film is still in the catalog, right?

    K-Lab Kodachome processing

    Maybe I'm just slow, but this thread is the first time that I've seen any real information about a recipe for making the K-14 developing chemicals. I am very happy to see that.

    I own the K-Lab that has been mentioned here and there and that I wrote about on the Kodachrome Project forum. I finally have some time to work toward getting the K-Lab restored and mechanically operational.

    I need help in getting a true and solid way to manufacture the K-14 specific chemicals to operate the K-Lab and develope 35mm Kodachrome. Since the K-Lab is much smaller than Dwayne's Kodachrome processor, the amount of K-14 chemicals is much smaller. That should help to keep the cost of supplies down and make the cost of developing individual Kodachrome rolls reasonable.

    Please contact me to help get Kodachrome developing rolling again.

    Kevin;

    See the US patent granted to R. Bent and R. Mowrey.

    I have 60 rolls of the last batch in the uber bottom of my freezer, I am sure the person on ebay "jel8080" who is buying up nearly every roll in sight would love to get their hands on it....but I would like to shoot it my self one day if a viable process comes about, so good on anyone for putting forth the effort...

    Hi all,

    Kevin - if I get you right, you are seriously considering trying to recreate a Kodachrome developing lab. If that's so, then please keep me in the loop. I'm aware of a shedful of enthuiasts sitting on rolls of Kodachrome in the blind hope that a new developer will emerge.

    Best wishes - and good luck,

    Brett.

    I've got 50 cartridges of Super 8 K40 in my freezer. One of these days I'll figure out how to expose it and develop it for B&W projection, at least. But if someone manages to get a K-14 cine film processor running, that would sure be fun.

The coating is so complex than only Kodak remained active in this field even though Fuji once made a compatible film, as did Konica in Japan.

    In the past aside of Kodak 7 more manufacturers made films on the Kodachrome principle.
