He was a photographic colour printer in the s, printing colour negatives mainly onto Agfacolor paper. Copying reflection color originals is one of the most challenging tasks you can encounter in color photography. The concentrate was diluted with six parts water to make a stock replenisher solution, and four parts of the stock solution were further diluted with one part water to make the working solution. This film is designed for. But, with more experience, he became adept at filtering out the slight change in colour when changing exposure times.
The process is identical for all subsequent film sandwiches in the enhancement process. This page last modified: Below are shown two boxes of Ektacolor Internegative film dated over 10 years apart.

And do take a look at Charlie’s site www. Run a test strip with a wide bracket range and evaluate from there.

I used to love to cross process some of the old Vericolor and pre-T-Grain films.
One negative is taped to a light box. I used the 9xi on full auto for exposure. This box dates from It internegatuve displays high color contrast that can affect its reproduction characteristics. Sounds like you have a few feet of it to experiment with.

These original astronegatives are then carefully sandwiched in register.
Even then, there is no telling how this film has been stored or what changes it has gone through over the years.
The developer working solution was made up of: Densitometers were also able to be connected to personal computers to eliminate most manual balancing operations. Add Replenisher plus Additive to the developer after processing each kodal of Print Film.
