... Apparently, Kodak had been forced to share the method with outlets to allow them to process it by this time.
After 1954, as a result of the case United States v. Eastman Kodak Co., this practice was prohibited in the United States as anticompetative. https://en.wikipedia.org/wiki/Kodachrome#Launch_and_later_history
I asked about processing time, and I'm told it was actually very fast, so definitely do-able if the right lab could be found. And that's really what it comes down to isn't it, was there a lab capable of doing it in the right area and that was or could have been open on a Saturday. As much as logic tells you the whole P G film is utter nonsense, unless it can actually be demonstrated that's that film wise.
It's more complicated than it seems at face value ...
First - the primary thrust and effect of the 1954 consent decree was to de-couple the sale of Kodak color film from prepayment of that same film's processing. It only meant customers paid for the film alone, then had to pay separately for submitting the film for processing. It turned what was originally one transaction (allowing the customer to shoot the film and mail it directly to a Kodak processing facility) transformed into two transactions. This did nothing to accelerate the overall filming / processing loop.
In the 1954 consent decree, Kodak agreed to make its processing technology and materials (chemicals) available to third parties. This agreement covered
all Kodak film formats (of which Kodachrome was the oldest and most complex specimen in color photography).
This doesn't mean everyone suddenly became capable of processing any or all Kodak film types. You still had to have the Kodak-supplied chemicals and the Kodachrome-specific know-how. If you needed to process Kodachrome quickly you needed to invest in one of Kodak's own Kodachrome processing machines. I've never been able to confirm that these Kodachrome-specific machines were even considered part of the 'technology' Kodak was required to share under the 1954 decree.
The speed at which Kodachrome could eventually be processed under the K-14 process might fit the required timeframe, but that process wasn't introduced until the 1970's.
Kodachrome was processed in large batches on dedicated machines, requiring 3 - 4 staffers (1 mechanic, 1 chemist, and 1 or more processing operators). It took 2 to 3 hours to load and warm up the machine before processing could be done. The core processing procedure would take at least 1 to 2 additional hours.
The photo professionals Long interviewed (two of whom had personal recollections of making Ektachrome copies of the original Kodachrome Patterson film) were consistent on the following points:
- Nobody in the Yakima / Seattle area could do initial processing of Kodachrome film in 1967. Accepting Kodachrome meant shipping it off to Palo Alto. Period ...
- Kodak absolutely did not operate their processing labs on weekends.
- It would cost at least $2000 to open up / start up a lab to do a processing run on demand and on a day the lab was otherwise shut down.
- The Patterson film from which the Ektachrome copies were made appeared to be standard Kodachrome.
- Nobody specifically recalled edge printing on the original film indicating where it had been processed (it should have including a code of 'P' or 'PA' for Palo Alto processing), but at least one of them stated the routine edge markings were visible, meaning it had been processed by Kodak.
I would also point out that I've never seen any account of that weekend's events that specifically claims, nor reasonably indicates, the film shown at DeAtley's house was Kodachrome rather than (e.g.) an Ektachrome copy. This always bothered me, because the color vividness of the former is markedly greater than the latter, and I've never seen any of the Sunday audience members mention the publicly-presented film (as of 1967 / late Sixties) being notably 'duller' than the one they saw at DeAtley's house.
