# Open-source film emulation LUTs

154 film emulation 3D LUTs from three open-source projects whose licenses allow commercial use,
collected in one place with their original licenses and a record of every change.
Each LUT keeps its own license: see the table and `LICENSES/`.

| File suffix | Project | Author | License | LUTs |

The spektrafilm author also asks (not a legal requirement) that the LUTs are not resold as a paid LUT pack
and not used to train commercial AI models. Please respect that.

Film and brand names are used only to say which stock a LUT approximates. None of the authors or this repository

## Files

- `luts/<category>/<code>_<source>[_<variant>].lut16`. Codes are neutral (category letter + number, e.g. `C04`)
  and never reused. Categories: `daily` (D), `pro` (P), `slide` (S), `cine` (C), `bw` (B), `instant` (I), `experimental` (X).
- `manifest.json`: every LUT with its code, category, source, the film it references (`reference`, the upstream name in
  `sourceTitle`), process, ISO, print paper, path, size and SHA-256.
- `CHANGELOG.txt`: what was changed, how, and by whom.
- `LICENSES/`: the original license texts.
- LUT format: 33³, `LUT1` + uint32 LE size + RGB uint16 LE, red fastest, sRGB in / sRGB out.

## Caveats

- spektrafilm and Spectral Film LUT simulate a negative printed on paper: whites sit around L* 83–90, not scanner white.
- Most RawTherapee looks were made by eye; they are not measured against film.
