Unireverse Film
Turns a scanned film negative into a positive — inverting in log-density the way film and paper do, then grading contrast the way a darkroom does.
Download — free public beta, macOS
Prefer no installer? Apple silicon .zip · Intel .zip. Checksums: arm64 · x64.
What you are agreeing to
- It is free. No licence, no key, no account. Every feature works.
- Exports stop on 31 December 2026. The date is stamped into the build. Past it the app still opens and still renders, and saving and exporting stop until you install a newer build. This is how the whole beta retires when 1.0 ships.
- Not for irreplaceable work. It is a beta. Keep your scans; treat anything it produces as re-makeable.
- macOS 14 Sonoma or newer. Older systems are not supported.
- Intel is built, signed and notarized, but not verified by hand. Apple silicon is the build that gets tested on real hardware. If the Intel one misbehaves, that is worth an email — it is the half nobody has watched.
Feedback
Bugs, crashes, a frame it converted badly: support@unireversefilm.com. That address is read by a person. There is no public issue tracker, so it is the only way through — and it is also how to be told when a new build is out, for the day the thing that is broken is the updater.
Useful in a report: the macOS version, Apple silicon or Intel, the version from the app's dock panel, and the scanner and file format the frame came from.
