Does anyone know how to make a selection by value in GIMP 2.9?
I'm trying to "cut out" saturated stars (values of 64k) in an astrophotograph. "Select By Color" should be able to do it, but the slider only goes to 256 (8-bit). I'd like to select pixels that are above, say, 40k.
Can anyone suggest a tool that is not PS assuming Gimp's devel 16-bit support isn't sufficient?
