    Dignan Photographic Report, 1975, Volume 3, p.91?
    Not having to do with K-14 at all, but is there a place to find the Dignan Photographic Report online or at least purchase something like a CD or DVD with copies?
    All this has happened before, and all this will happen again.

    Since we do not know what Steve actually used, it is presumptuous of us to assume that he used the basic chemicals. For all we know, he used the real stuff.

    Also, Pat and I used to correspond and talk on the phone way back when. I know for a fact that he did not always get everything right, so check the formulas out. I never saw that particular publication so I cannot say, one way or another.

    At one time you could get the whole collection on microfiche, remember this was before personal computers. Perhaps inter library loan from a big library.

    If someone really wants to go on a treasure hunt, I have a clue for you. Remember that Kodachrome was also sold as a movie film, and movie film gets processed by big labs that needs lots of detailed info, not just idiotproof instructions for operating a K-Lab. For instance, in documents readily available on their website Kodak spells out every possible detail, including chemicals, needed for processing the current ECN-2 film. So you have to figure they did that back in the days of Kodachrome movie film processing too, right? Well, go look at a Kodachrome movie film data sheet still available on Kodak's site:

    http://motion.kodak.com/motion/uploa...DACHROME40.pdf

    Right there on the first page it says:

    PROCESSING
    Process K-14; see TI0780 for Mechanical Specifications and
    TI0836 for Chemical Solution Formulas.

    Anyone got a copy of TI0836 handy??

    And this is no secret, but in case anyone here didn't know, the K-Lab instructions, which include a very thorough discussion of the processing theory, are still up on Kodak's site, you just have to get all 10 sections one by one. Number 3 is the really interesting one!

    <snip....snip.....snip>

    Time was when Kodak would go out of its way to help the consumer. George Eastman made his reputation by replacing all of the film plates he sold which were contaminated with bad gelatin. The cows from which the gelatin was made had eaten mustard plants and this material caused the photographic plates to fog. Eastman replaced the plates at no charge and hired chemists to get to the root of the problem. Bradford Washburn used Kodachrome to photograph Alaska when the sheet film first came out. But he was given tungsten film and did not use a filter to correct for daylight. Dr. Wesley Hanson worked out a process to correct for the wrong exposure in the lab and many of the images were saved. Can't we recover that helpful spirit? Just saying....

    Judging from some of the replies on this thread, the answer would be no. Some of the comments on here are getting downright mean. Yes, we are well aware Kodachrome is not being produced. Yes, we are well aware that Kodachrome will never be produced again. Yes we are also more than aware that the processing has also ended. But does that mean that you have to keep hammering us over the head with it? There are obviously people who want to discuss Kodachrome. Where is the harm? If you are getting so steamed up, just stop reading the thread. Belittling someone because they want to talk about developing Kodachrome is not going to end things any faster, we are all adults, lets start acting that way and not like the US Congress has recently.

    Absolutely. It's silly to call for closing a thread just because you don't like it. Don't like it, don't play. As long as its respectful and more or less on topic, and Kodachrome will always be on topic in an analog forum if only as history, people should talk about it if they want to.

    Friedman's book was published long before K14.

    Im sure i remember reading one of his posts here that said the chemistry was not the same as Kodaks, so would not work in the K-lab.

    If anyone has a copy of "TI0836" it would have to be Dwaynes.
    Im actually surprised no one has approached Dwaynes in regards to this earlier, since their staff would have the best knowledge and experience in processing the stuff!

    Yes those instructions for the K-lab have been online for some time!
    They should be grabbed now before Kodak remove that old part of the site!
    Very interesting in regards to how the process runs. There is another datasheet ive seen with microscopic cut away images of the layers of processed Kodachrome, very interesting.

    Dwayne's probably bought prepared "kits" from Kodak. They would not have hand mixed IMHO.

    MP labs typically hand mix.

    Kodak supplied Dwaynes with all the chemicals in their crystalline form, they did not have to synthesise the end product of course, but they had to prepare all the mixtures to the right dilution etc.
    Thats why a trained chemist was required to run the large scale K-14 machines, in addition to mixing them correctly, they needed to constantly monitor the chemicals and regularly replenish them.
    As far as im aware with the K-labs, the chemicals were already mixed to the correct strength and sealed in bags flushed with nitrogen, so that the mixed chemicals did not oxidise.
