Glow

This effect makes parts of an image glow brighter by working on the luminance channel of an image. The Glow is the superposition of the base image and a modified version, where bright areas are blurred.

To "animate" the glow effect, mix it with the base image using the Gamma Cross effect, crossing from the base image to the glowing one.

Options

Threshold
Areas brighter than the Threshold are blurred.
Clamp
The maximum luminosity that is added.
Boost Factor
Multiplier of the brightness.
Blur Distance
The size of the blur.
Quality
Improves the quality of the glow by giving smoother results but will be slower.
Only boost
This checkbox allows you to only show/use the "modified" version of the image, without the base one.
