A concentrate kit for developing ECN-2 cine negative film at home — enough for 8–10 rolls. Remjet prebath, developer, bleach and fixer in four bottles, from which you make up 500 ml of each working solution. They mix with ordinary tap water — no distilled water needed.
What is in the kit
Four concentrates — remjet prebath, colour developer, bleach and fixer — packed as 100 + 50 + 50 + 100 ml in a zip-lock bag with a printed instruction sheet, making up 500 ml of EACH bath — a full set of solutions for the stated yield. The prebath is exactly what separates a complete ECN-2 kit from a C-41 one: without it the remjet stays on the film.
What remjet is, and why it dominates here
Cine negative film carries a black anti-halation layer (remjet) on the back. It does not dissolve in the developer, and if you do not remove it first it comes off in flakes inside the tank: it contaminates the solutions, the reel and the emulsion itself, and those marks cannot be cleaned off afterwards. The prebath in the kit softens the layer so it can be rinsed away with water. It is the first stage, and it cannot be skipped.
How far it goes
The kit covers 8–10 cine rolls, which works out to roughly 80–100 ₴ of chemistry per roll. The exact figure depends on your tank volume and whether you rotate the solutions. The figures above are for the default size; the larger kits on this page work out cheaper per roll, and the selector above recalculates both price and yield.
ECN-2 in two sentences
ECN-2 is the process cine negative was designed for: the developer runs at 41 °C, while bleach and fixer are far more forgiving. Compared with C-41 you get the colour rendition the manufacturer intended rather than whatever comes out. Take the actual times, stage order and tolerances from the instruction sheet in the kit.
What else you need
A tank and reel, an accurate thermometer, measuring vessels, a water bath for 41 °C, and plenty of water for the remjet rinse — you rinse until the runoff is completely clear. The equipment is in the darkroom and accessories sections; cine film is in the film catalogue.
Frequently asked questions
Can I develop cine film in a C-41 kit?
Only if the remjet has already been removed at the factory — those films develop in C-41 as an ordinary negative, though the colour rendition differs from native ECN-2. Do not put remjet-backed film into C-41: the layer will contaminate the solutions and the reel.
Can I remove remjet with soda instead of the prebath?
Home-made solutions for this do exist, but the prebath in the kit is matched to the other solutions and to the times in the instructions. If this is your first ECN-2 run, it is safer to follow the process as written and experiment later.
How long do the diluted solutions last?
The shelf life is given in the kit instructions. The colour developer oxidises fastest — keep it in a tightly closed container with no air space, and do not mix more than you plan to use soon.
If you would rather not do it yourself, or you need a finished scan, we develop and scan colour film.
