    Well, IDK if the color developers were in 2 parts in the machine or not. I do know that they go bad fast when fully mixed. The tanks themselves become bright Cyan, Magenta and Yellow. Very messy.

    And yes Fred, it is RX like. Ahhh, the good old days. Hope you had a nice lunch.

    Correct me if I'm wrong, but if you had three sheets (R, G, and B, to keep it simple...) you wouldn't necessarily have to re-expose to Red, Green, and Blue light, you could (since the exposure is on three separate sheets) re-expose each sheet to white light, then redevelop the R sheet in the cyan developer, the G sheet in magenta developer, and the B sheet in the yellow developer, right? That would eliminate the complexities of filtration and exposing only one side. Of course then you'd have the registration problem when you went to put it back together. IDK.

    There are some things I should mention about this test....

    1stly : I have absolutely no intention of offering it as a service. The Cost, The limited amount of chemistry I have for this process and the fact no new film stock is being produced means this just wont happen.

    2nd : While the thread states HOME processing people should be aware that I am working in a fully equip professional photographic lab which without I could not have done this process.

    3rdly: While Kodachrome is process K-14 I did not strictly process this in k-14 chemistry. It was processed using an butchered version of this process and other improvised adaptations which can yield a result but the chemistry does not keep nor can I guarantee the archival properties of the final product. Its a one shot process.

    Thanks for the interest in one of my personal tests .

    You do realize you now officially stole the title from Dwayne's Photo for "Last roll of Kodachrome processed", correct? You also stole the tile of "Last roll" from Steve McCurry as well. Congrats on re-writing photographic history!

    Awesome

    They'll just keep it the same and add the word "commercially" in whatever books covering said subject.

    This is exactly correct. And, the color developers would be much simpler.

    Registration would not be a significant problem, as many processes used it in the past. The real problem is the thickness of 3 sheets of support which may cause some sharpness problems. IDK for sure.

    Thanks PE. That's what I thought. Sharpness problems would probably be lessened for projection (or even scanning) if the three positives were bigger than 35mm, or even medium format. Of course if you're gonna scan it, all you really need is the separation negatives and put it back together in post - which of course makes it a hybrid process. At least for me the reason to shoot chromes is for projection (secondarily to have a good color reference in-hand to give the printer for prints).

    <tongue-in-cheek>Who's gonna start making this new Apugchrome film and a camera to shoot it in? </tongue-in-cheek>

    I have just about everything to do this, but want to confirm sources and chemicals with Steve.

    I think there are a few Kodak marketing people still with us.

    My Dad looked still reasonably spry today when I visited him. He may have been retired since the mid 1980s, but he was employed by the marketing division of Kodak Canada for the previous quarter century or so.

    And as was common in his time, he had a pretty good knowledge about the practical technicalities of Kodachrome and Ektachrome, because that was important if you worked in the marketing department.

    Correct spools, reels for a complete film would be a nightmare and I have not and will not explore that avenue. All my tests were with very easy to manage strips no longer than 5 or 6 frames.

    correct.
