Bloom
This filter simulates the effect of extremely overexposed highlights on film. Highlights
above a certain threshold are blurred, brightened, and recomposited with the original.
All unaffected regions of the image interact with the glow effect, but otherwise retain
their detail.
Parameters in the Inspector
Amount: Sets the amount of the bloom. Values range from 0 (no bloom) to 32.
Brightness: Sets the brightness of the bloom. Values range from 0 to 100.
Threshold: Sets the luminance threshold at which the bloom starts. Values range from
0 to 100.
Horizontal: Sets the distance of the bloom’s horizontal offset. Values range from 0 to
100.
Vertical: Sets the distance of the bloom’s vertical offset. Values range from 0 to 100.
Crop: Toggles whether or not the bloom is cropped at the original boundaries of the
object.
