I made presets for Darktable which mimic Fujifilm's Film Simulations

Fujifilm cameras make really beautiful JPEGs thanks to their Film Simulation feature (where they mimic the look of certain analogue film types), but sometimes I want to do things for which you need the RAW files (like sharpening or local contrast effects or white balance fixes or whatever else would suffer under 8-bit/channel and/or JPEG artifacts).darktable is my RAW editor of choice, but it doesn't make your edits look like the out-of-camera JPEGs by default. Quite the contrary, the defaults generally need some love to bring out a nice edit of an image.To solve (pun intended) that, I wrote a Python tool called dtsolve. It generates a darktable preset (style) from a pair of images (OOC JPEG reference and RAW) and I used that to make styles for almost all Fujifilm Film Simulations.The linked announcement post includes an interactive widget to try them out in the browser and download links for darktable users to try at home.Have fun!(I'm going to write a follow-up post at some point to detail more how dtsolve came to be and how it works.)
