OpenDRT for ART

Also I forgot to answer to this:

One other thing I noticed is that for the info here it mentions that $HOME/.config/ART/ctlscripts works as a default directory to load CTL files from, but it doesn’t appear to work until you manually add that folder in the preferences. Just wanted to check if this is a bug or if it is out of date information.

That’s intentional, and the information is still correct. There are actually two places in the ART pipeline where CTL scripts can be used:

1. in the “Color/Tone correction” tool (under “Local editing”)
2. in the “Film Simulation” tool

The above path refers to the 1st case, where you want to use CTL scripts to implement additional modes for the Color/Tone correction tool. If you put your scripts in $HOME/.config/ART/ctlscripts, they will appear in the drop-down list of that tool. This is meant for scripts that implement various “creative grading” effects that operate on scene linear data. There is a collection of such effects (of varying usefulness and quality) in the ART-ctlscripts repository.

Scripts added to the “Film Simulation” tool, instead, are meant to implement “display transforms” or other similar scene to display mappings (such as darktable’s sigmoid or the integration of AgX emulsion).

Hope this helps
