I am new to darktable, but have worked with luminosity masks in photoshop before using Tony Kuyper’s panels.
I found articles on how to create luminosity presets in darketable. These articles were very helpful and I created the presets for future use in the tone curve module. I then realized they are not available while using other modules.
Perhaps I am doing something incorrectly? Is there a way to create the luminosity masks one time and have them available in all modules?
