A Cheap Luma Key


A ˜Cheap Luma Key

Need to quickly knock a color out of your background for compositing. Sure, if it was a color , you could try chroma keying it, but what if it's black or white? Luma key, right? Don't bother. Modes are much faster for a simple luminance key.

  • For a white background, set the layer to Multiply.

  • For a black background, set the layer to Screen.
