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
