Eliminate Dark/Light

[ReMake]

This is very simple effect which allows to eliminate dark or light areas of the image. Good deletes black or white color (as a special case of dark or light, respectively).

 

The effect has a very simple interface. You can find it under Effects-> Color-> Eliminate Dark/Light.

P.S. I decided to start a new topic, because the former name of the topic Eliminate Black/Eliminate White was wrong.
