I need to use a gradient-mask where the Max side is limited to a specific distance and not to the image edge … ideas anybody!1
combine it with other drawn shapes?
Just to add to @paperdigits advice, look at videos about Darktable’s mask manager. There are some powerful tools there that you may be unaware of.
I could not remember the trick with this gradient-mask … the combination with other masks sounds correct but simply does not work but I finally did get the result by using a second ‘opposing’ mask … that does it!! I had seen it elsewhere a long time ago.
