Well, I just got the Third Edition (1946) of the Kodak "Kodachrome and Kodacolor Films" databook. We've previously noted that the original Kodacolor (1942) was only 6 exposures per roll, and came with a pre-exposed "control strip" at the end of the roll. But, they make it clear that by 1946, they weren't doing that anymore. However, it was still 6 exposures per roll, because they film was much thicker than normal films. What is interesting, and raises questions on my part, is that at this point they had added a positive contrast mask to the film. It was the layer immediately under the yellow mask. The question is, how did they make this work in the processing? Normally one bleaches all the silver out of color film after the color development stage. Not only were they leaving some silver in the film (but only in this layer), but they were reversal processing it, requiring either chemical or optical re-exposure. An interesting comment is in the text: "The Kodacolor process reproduces colors with sufficient color fidelity to afford attractive color prints. It is not intended for the making of color records, or for matching or measuring colors." I wonder if this was due to limitations of the printing process. The printing process was clearly limited, as all prints were 2-7/8" wide, with length set by the aspect ratio of the negative. No enlargements. So it must have been a rather involved long process, done in long rolls. Of source, we really can't know now, except from memory. All the Kodacolor prints from that era have faded into horrible yellow now. Do some folks here have hands-on memory? Of course, maybe the above quote just reflects the reality that the color balance of a color print is ultimately a subjective decision on the part of the person making the print. I have some Kodacolor negatives from 1960, and I've found that they scan very nicely, and make very nice digital prints. They look much nicer than period prints, which always look rather contrived and pastey. The scans have very nice clear colors, especially gorgeous yellow, and a lovely sky. I suspect that the print paper was far worse than the film for quite a long time. But, of course this is C-22 film, which could well be much better than the original Kodacolor process.
