    Very interesting stuff, PE. Thanks for the input on this thread. So in say the FTD, there were people manually developing film over and over again at different temps, with different chemistry, for different gradients, etc etc? If we take one film testing example, say determining the recommended development time for 35mm Plux-X in a small tank at 68F for a given desired gradient, how many times would a specific test be repeated to generate data?

    Well, Michael, substitute PTD for FTD in your post. FTD did routine standard tests - more or less release testing. PTD did the stress testing of the system and did the variations. They would test film in all developers at all combinations of time and temperature and in all equipment available. Totally different work in the two divisions.

    One test was not enough, they were run multiple times and run through a statistical program to get variations and etc.. so we knew what to expect from both standard deviation of product and from errors by the customer.

    PTD was by far the larger division when compared to the FTD.

    At one time, the color processing labs were attached to the PTD. This was, I think, for quality assurance.

    Wow, imagine the amount of processing going on. Over and over again, changing one variable at a time. Very interesting. This is exactly the kind of thing I think about when I do my film/developer tests. Trying to be thorough and get repeatable results takes a hell of a lot of time. Although at least the EK test force had well controlled facilities to make things much more efficient. I'm thinking for example about how much time I spend just getting the temperatures right and then trying to maintain them. Clearly in a Kodak research facility it would be easier to do high volume testing under controlled conditions.

    Our sinks were larger than the common bathtub in some cases. They were double jacketed and insulated. They were powered by steam (yes steam and were they noisy when heating up) and by chilled water.

    We had DW, DI and tap water piped to every darkroom along with nitrogen. We had a stockroom with literally thousands of chemicals and almost any type of equipment you can imagine.

    Incredible. An amazing place it must have been.

    And, for my first 20+ years there, we got all the film we could use + processing!!!!!! This encouraged us to become good photographers.

    Much of the experimental film was also given away. I have many rolls of experiments here in black canisters and with just a number and process on it.

    Times have certainly changed.
