Answers to @MiltonPhoto's rant with darktable's 4.0 new features

‪@MiltonPhoto‬ posted an open source rant yesterday : Video. While I can get behind most of the critics, I feel some of them might stem from underusing what's already in the soft. In any case, darktable 4.0 will be released with new color features that will help a lot getting reliable colors from start to finish, and even to nail any particular image content to a specified color target defined in CIE Lab, which falls exactly in the use cases described by Shane, so it's a good opportunity to present them.

Here is the documentation for each of the presented features :

* Batch-processing workflow : https://docs.darktable.org/usermanual...
* Spot color-mapping in color calibration : https://docs.darktable.org/usermanual...
* Color Checker calibration : https://docs.darktable.org/usermanual...
* Spot color-mapping in exposure : https://docs.darktable.org/usermanual...
* Filmic v6, background explanations of the gamut-mapping : https://docs.darktable.org/usermanual... and https://docs.darktable.org/usermanual...
* The brand-new darktable UCS 22 color space developed for artistic saturation changes at constant brightness, taking Helmholtz-Kohlrausch effect into account : https://eng.aurelienpierre.com/2022/0...
