Glow2
Glow2: makes bright areas glow — the parts above tolerance are blurred (size, filter, quality as Blur), tinted, saturated, scaled by brightness and added to the image.
Glow2: makes bright areas glow — the parts above tolerance are blurred (size, filter, quality as Blur), tinted, saturated, scaled by brightness and added to the image. effect only gives the glow alone. Width channel lets another channel scale the glow size per pixel; crop to format works as in Blur.

Nuke equivalent
Imports from and exports to Nuke's Glow2 (Glow also import to it). The standard Nuke mask knobs (channels, mask, invert, (un)premult, mix) are mapped too.
Knobs with a different name here:
| Nuke knob | Knob here |
|---|---|
W | width_channel |
Nuke knobs not in this list import as a knob of the same name, or are kept unchanged for export. See .nk import.

- Glow (
examples/filter/glow.oink): Glow adds a blurred copy of the bright parts back on top. Tolerance sets how bright a pixel must be to glow.
