Film stock profiles for color negatives

Last updated 2 June 2026

Not all color negative film inverts the same way. The orange mask and color response differ between stocks, so a one-size invert leaves some rolls off. EditMe ships per-stock profiles tuned for common films, Portra 400 and 800, Cinestill 800T, Gold 200, Ultramax 400, and Ektar 100, plus a generic fallback, so each negative comes out closer to right.

Why per-stock profiles matter

A color negative's orange base and color layers vary by film. Portra renders skin one way, Cinestill 800T carries a tungsten balance and a known halation, Ektar is more saturated. Inverting all of them with the same numbers means hand-correcting afterward. A profile tuned to the stock starts you much closer.

Which profile for which film

EditMe includes profiles for Portra 400 and 800, Cinestill 800T, Gold 200, Ultramax 400, and Ektar 100, with a conservative generic fallback for anything else. Pick the stock you shot, and the C-41 inversion uses numbers tuned for it. It all runs on the device, free as part of the core inversion, and your scans never leave the iPhone.

Frequently asked questions

Which film stocks does EditMe have profiles for?

Portra 400 and 800, Cinestill 800T, Gold 200, Ultramax 400, and Ektar 100, plus a conservative generic fallback for other film.

Why does the film stock matter for inverting?

Each color negative has a different orange mask and color response, so a profile tuned to the stock inverts closer to right than one generic setting.

What if my film is not listed?

Use the generic fallback profile. It is conservative and gives a reasonable starting point you can fine-tune.

Is this free?

Yes. The per-stock C-41 inversion is part of EditMe's free core, runs on the device, and your scans never leave the iPhone.
