I finally dare to write here, I was waiting for the time. I have been reading many things about color chemistry in this forum for years, the contributions of Photo Engineer and many others who have not been afraid to experiment when processing "supposedly dead films".
My first approach was with a 120mm roll of Ektacolor type S, from 1964 (my God, what a wonder to simply open it, the metal chassis, the small information leaflet ... the details were taken care of). I develop it with chemistry c41 at 20º based on information that I have been reading out there, unfortunately I did not get to the bleach bath of ferrocyanide but the next one will be better.
My next test I want to do it by formulating exactly the original chemicals, here in Europe it is very difficult to find CD3 but I think that is already solved thanks to an Italian supplier.
For this first test I used an EI of 3 and miraculously there is an image and there is color ... so I suppose that when I have made the appropriate formulation with the appropriate chemistry the result will improve, even so I will give it a couple more points ... the film has been sleeping there for 56 years, a little more light sure suits him.
Any advice will be welcome.
Forgive my English, it's not mine ... it's from google.
P.S. I forgot the question .... my idea when formulating the original chemistry is to increase some quantities thinking about how old the film is in order to get more color ... the initial idea is to increase the amounts of benzyl alcohol and cd3 but I don't know how far I can add these chemicals without spoiling the rest of the formula
