Each LUT keeps its own license: see the table and `LICENSES/`. | File suffix | Project | Author | License | LUTs | | --- | --- | --- | --- | ---: | | `_sk` | [spektrafilm](https://github.com/andreavolpato/spektrafilm) | Andrea Volpato | CC BY-SA 4.0 | 14 | | `_sl` | [Spectral Film LUT](https://github.com/JanLohse/spectral_film_lut) | Jan Lohse | MIT (software) | 39 | | `_rt` | [RawTherapee Film Simulation](https://rawpedia.rawtherapee.com/Film_Simulation) | Pat David, Pavlov Dmitry, Michael Ezra et al. | CC BY-SA 4.0 | 101 | ## Attribution - Derived from spektrafilm by Andrea Volpato · https://github.com/andreavolpato/spektrafilm · Licensed CC BY-SA 4.0 · Modified by NicePhoto - Generated with Spectral Film LUT by Jan Lohse · https://github.com/JanLohse/spectral_film_lut · MIT License - RawTherapee Film Simulation Collection by Pat David, Pavlov Dmitry, Michael Ezra et al. · Licensed CC BY-SA 4.0 · Resampled by NicePhoto 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.

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.
