I'm working with the ColorMask Script in PI to shade parts of the nebula. I find that often times with masks, there are areas in the mask that I would like to not use. It might be some wayward nebulosity or something like that. I've used the CloneStamp tool to actually paint out those little "bad spots" but I'm not really happy with the the CloneStamp in PI. I much prefer the one in Photoshop. At any rate, does anyone know if there is another tool in PI to finesse masks? I hope that makes sense.
