How do I know if my film has Remjet?
REM-JET (or RemJet) is a removable jet black layer. The black coating, made of carbon particles, is located at the bottom of the film.
What is a Remjet layer?
Remjet is a protective layer on the base of motion picture film that protects from light piping, base scratches, static, and halation of highlights in exposure. It was notably used on Kodachrome (K-14 process) originally in still photography. CineStill films do not have remjet backing.
What is ecn2?
ECN-2 film is similar to C-41 film but has a Remjet coating so it can’t be processed in a standard film processor. Example film stocks include Kodak Vision3 500T, 50D, 250D, Fuji Eterna 500T, Seattle Filmworks, Signature Color, etc. All film will be cross-processed in C-41 chemistry using a rotary processor.
How do you develop ECN-2?
The ECN-2 consists of the following steps:
- Remjet Prebath (80°F – 10 Seconds – No agitation)
- Developer (106°F – 3min, 2-inversions every 15 secs)
- Stop (80°F – 100°F – Continuous Inversions for 30 Secs.)
- Bleach (80°F – 100°F, 3min, 2-inversions every 15 secs)
- Fix (80°F – 100°F, 2min, 2-inversions every 15 secs)
What’s the best way to remove Remjet film?
To remove remjet, bathe in washing soda crystals at about 50 – 100 g/l in warm water (not over 100 F or 40 C). Use a sponge to wipe off the film back. Change the soda bath and repeat. Then wash for 10 minutes in running warm water and then bathe in the C41 final rinse.
What does the Remjet layer on Kodak film do?
As explained by Kodak…. “Remjet, a removable jet black layer, is the coating of carbon black particles in a water-soluble binder on the bottom of the film. It has four purposes: antihalation, antistatic, lubrication, and scratch protection.
What does Remjet do in a low humidity environment?
This is especially important in low relative humidity environments. Remjet also has lubricating properties.
