This is a work in progress, and will be further supplemented, updated and improved as time goes on.
Latest Update: April 2021 – Added new list for presets intended in Darktable (below presets RawTherapee)
Presets for Rawtherapee :
Film Simulation Profiles ( presets ) are scripts, text files (.pp3) that can be applied in RawTherapee on any image

Where to find (the latest can be found at the bottom of the list ) :
- Sébastien Guyader and Pat David – https://github.com/pixlsus/RawTherapee-Presets
- GLTR87 – RawTherapee-presets-Fuji-inspired : https://github.com/GLTR87/RawTherapee-presets-Fuji-inspired -> note from author :
- “The presets were calibrated with a Sony A7 camera, but they give good results with Canon 5D and Olympus X-Z1 RAW files, and probably others.”
- Stefan Chirila – Custom Chrome – 6 sets packed with presets : http://www.stefanchirila.com/customchrome/ realy tons of presets, awesome Stefan, thanks !
- My own collection together with HaldClut : https://www.digicrea.be/picturefx/
