What it does
Spectral Film LUT digitizes published film datasheets and runs a multistep color pipeline that simulates how a negative reacts to light through to the final print, for still, motion-picture, color and black-and-white stocks. Pick a sample image in your input color space, tune the preview and export one LUT, or separate negative and print LUTs so grain, halation and printer-light controls slot in between, with a recommended Resolve node tree. Runs as a GUI from a Windows .exe, Linux AppImage or pip install spectral_film_lut; accuracy is limited by the published data. MIT.
Use when
- Give AI-generated footage a real film-stock look
- Export a film-emulation LUT for DaVinci Resolve
- Split a look into negative and print LUTs with grain and printer lights
- Compare Kodak and Fuji motion-picture or still stocks on a sample frame
Install
- local:
pip install spectral_film_lut - Any agent, with the vargai CLI:
vargai install spectral-film-lut
