In an image, I'm trying to select the "Vuo black" (like the black that results from empty space with
Render Layers to Image) by using
Mask Image by Brightness.
The settings give me pause. How to set the Preserved Brightness? 0.01 to 1? 0.001 to 1? 0.0001 to 1? What is the good setting to catch only the "Vuo black"?
And then, the Brightness Type, again, in conjunction with the Preserved Brightness, what is the good setting to catch only the "Vuo black"?
