I have a physical object that was shot with a green Chroma Key muslin background. The physical object has small parts in it that have green. When I use Color Difference or Chroma Key for the green removal, it removes these small green sections on the object. Is there a mask or some process I can use to isolate the small green parts of the image and prevent them from being Chroma Keyed out?

Thanks for the help! Gary

Yeah, you can use a Garbage Matte to retain those areas. There is a control to select whether the garbage matte retains or removes the area it covers, so just make sure you select the right one.
