Under Linux in DT 3.4 when I imported images into light table I could define that darktable exported folder became a sub folder of the original folder. I can not do that in DT3.6. I now have to define a new folder.
To give a concrete example
My images are in a folder /dev/md0 mounted as a raid drive as /pics. They are in fact in a folder /pics/2021/08-2021/exp
After processing in DT I want them to be automatically saved to a sub directory …/exp/darktable exported.
Then if I chose another folder say …/countryside
I want the exported images to be saved automatically to …/countryside.darktable exported
I hope that I have made this clear and that I haven’t missed some simple folder naming criteria.
You want to use variables in the export dialog: darktable 3.6 user manual - variables
