Lumakey RGB

Overview

Mixes a foreground and background image, replacing the foreground image with the background image in areas where the foreground's brightness (luminescence) is either above or below a chosen level.

Properties

Controls

Layers

Choose the foreground and background layers.

Luminescence

Choose the level of brightness (luminescence) that should be included or excluded from the foreground image.

Tolerance

It is unlikely that you will want to isolate just a single colour, so the tolerance value lets you select a wider range of similar colours. The larger the tolerance value, the greater the number of colours that are isolated.

Feather

Determines how the isolated range of colours blend into the background. A larger value here provides a softer "feathered" edge between the colour and the background.
