I've been looking for some time to find any more detailed information on how ECN-1 film was developed.
And yes, I am actually talking about ECN-1, not the current ECN-2.
The only reference I found being mentioned so far was
"Hanson, Wesley T. Jr. "Color Negative and Color Positive Film for Motion Picture Use." Journal of the SMPTE, March 1952, Volume 58, pages 223–238."
Unfortunately my existing IEEE access does not include this paper and I cannot find this paper elsewhere nor any other one with any more details than what Wikipedia and similar sites say, like "develop at approximately 25°C for around 7–9 minutes", that's it, no other steps are mentioned. Aren't there any public notes on this, for ECN-2 for example all steps are available in written form to everyone?
Does anyone have any notes on the actual process, steps, temperatures and times?
This would be very interesting for me to read!
