LumaKey Invert

[Viaplana]

Hi!

I'm a new Isadora user, this is my new post in this forum:

I have prloblems trying to keying out brighter pixels while keeping darker pixels from a camera input. When I try to do it with LumaKey actor, it does the oposite: it keeps brighter pixels while key out darker. I have also tried to do it with ChromaKey but it doesn't work with black. 

Do you know any way for doing it?? 

Thanks!
