Glow filters combine blur with brightness and color effects. The results are automatically recomposited over the original image in various ways. Glows can be used to simulate film effects, as a method to render your footage more abstract, or as accents to make elements in a composition stand out.
There are nine Glow filters:
Aura adds stylized light or dark halos around well-defined areas of an image.
Bloom simulates the effect of extremely overexposed highlights on film.
Dazzle adds glowing star-shaped accents to the highlights in an image.
Glint adds a bloom effect and rays of light to the brightest portions of an image.
Gloom creates a muted, dark glow.
Glow creates a basic glow effect.
Light Rays creates light rays shining through an image from a specified point.
Outer Glow creates glow around the outside of an image.
Overdrive creates an animated glow by compositing numerous glowing tinted duplicates of the original image.
