Optics
Bloom
Bright areas bleeding light into their surroundings.
Controls
- threshold
- What counts as bright. It moves the edge of the glow, not its strength — white glows fully at any threshold
- intensity
- A number from 0 to 2, 0.8 by default.
- radius
- How far the glow spreads from a bright place
- quality
- How many blur passes are stacked. One leaves a hard step at the edge of the glow, three a soft falloff — and a wider halo
- tint
- A colour, #ffffff by default.
- blend
- How the glow is laid over the picture: added on top, screened, or only where it is brighter than what is already there
