PSI ECN-2 Powder Kit – Reliable 2L Motion Film Developer

Introduction

If you’re a film shooter looking to process your own motion picture film at home, the PSI ECN-2 Powder Kit is one of the most reliable and accessible ways to achieve consistent lab-quality results. This 2-liter kit is designed specifically for the ECN-2 color negative process, which is used to develop professional motion picture film stocks such as Kodak Vision3 500T, 250D, and 50D.

With the PSI ECN-2 Powder Kit, home development of cinematic film becomes affordable, predictable, and safer. This kit comes with all necessary components in powdered form, offering extended shelf life and easy storage compared to pre-mixed solutions.

 What is ECN-2 Film Processing?

ECN-2 is the standard color negative development process used in the motion picture industry. It’s optimized for high-quality image reproduction and wide dynamic range, especially when scanning film for digital workflows. Unlike C-41 film (used in still photography), ECN-2 involves an additional step: remjet removal — a black anti-halation layer found on motion picture films.

The PSI ECN-2 Powder Kit is formulated to follow this professional workflow with ease. It’s designed for home labs or small studios looking to shoot and process cinematic films with the same integrity found in motion labs.

 What’s Inside the PSI ECN-2 Powder Kit?

Each PSI ECN-2 Powder Kit includes:

• Developer

• Stop Bath

• Bleach

• Fixer

• Prebath (optional for remjet removal)

• Clear instructions for mixing and use

Once prepared, this kit yields up to 2 liters of working solution, enough to develop multiple rolls of 35mm, 16mm, or Super 8 motion picture film.

 Key Features of the PSI ECN-2 Powder Kit

• Makes 2 liters of working solution

• Powdered chemistry for longer shelf life

• Formulated for motion picture film stocks (e.g., Kodak Vision3)

• Supports 35mm, 16mm, and Super 8 film

• Includes remjet-safe workflow

• Ideal for home and indie film labs

If you’re shooting motion picture film like Kodak Vision3 500T, the PSI ECN-2 Powder Kit allows you to get clean, color-accurate results without sending your rolls to a professional lab.

 ECN-2 vs C-41 – What’s the Difference?

While both ECN-2 and C-41 are color negative processes, they are not interchangeable. ECN-2 uses a different chemical formulation and temperature, and motion picture films contain a remjet layer that must be removed before development.

The PSI ECN-2 Powder Kit is specially designed to handle these differences:

• Remjet removal-safe formula

• Proper development curve for Vision3 film

• Film-safe pH balance and development time

Using a C-41 kit on ECN-2 film can lead to muddy colors, base fog, and incomplete remjet clearance. Stick with the ECN-2 Motion Picture Film Developer Kit for correct results.

 How to Use the PSI ECN-2 Powder Kit

Using the PSI ECN-2 Powder Kit is simple:

1. Mix the powder chemicals with distilled water as per included instructions

2. Pre-soak your film (optional, but recommended)

3. Use a remjet removal bath if needed

4. Develop at 41.1°C (106°F) for the recommended time

5. Proceed with stop bath, bleach, and fixer as per ECN-2 workflow

6. Final rinse and drying.

You’ll need a temperature control tool like the Cinestill TCS-1000 for consistent heating. This is especially important for ECN-2 film development.

 Which Films Work with PSI ECN-2 Powder Kit?

The following films are compatible with the PSI ECN-2 Powder Kit:

• Kodak Vision3 500T (5219 / 7219)

• Kodak Vision3 250D (5207 / 7207)

• Kodak Vision3 50D (5203 / 7203)

• Kodak Vision2

• CineStill films (converted ECN-2 films)

Note: CineStill film has the remjet layer pre-removed, so it can be processed in both C-41 and ECN-2. However, the ECN-2 Motion Picture Film Developer Kit provides a truer color response designed for original Kodak motion films.

 Shelf Life and Storage

One of the advantages of the PSI ECN-2 Powder Kit is its long shelf life. In powder form, the kit can be stored for over 12 months in a cool, dry place. Once mixed, solutions should be used within a few weeks, depending on storage conditions.

Keep solutions in airtight, dark chemical storage bottles for best results. You can find suitable bottles here.
