Bloom

Bloom finds the pixels above a brightness floor, blurs them, and adds the result back over the frame. This creates the glow around bright surfaces such as emissive panels

Controls

ControlRangeDefaultEffect
Bloom TypeNormal / Streak / StarNormalA soft halo, anamorphic streaks, or star rays
Intensity0 – 100How much glow is added back
Threshold0 – 20.5The brightness floor a pixel must clear to glow
Threshold Smoothness0 – 10How gradual the transition into glow is
Radius0 – 61How wide the halo spreads
Saturation−1 – 10How vivid the glow itself is
ColorHex#ffffffColour the glow is tinted with
Opacity0 – 11How strongly the glow blends with the image

Intensity defaults to 0, so switching the effect on changes nothing at first — raise it before the glow appears

Bloom is additive, so it only ever brightens. A frame with nothing above the threshold renders identically with the effect on or off

Bloom Type

Normal is the soft halo spreading out from a highlight, and the setting you want most of the time

Streak simulates the long flare of an anamorphic lens by stretching highlights along one axis

Star pulls highlights into rays along several axes, the way a light source flares through the blades of a lens aperture. Selecting it reveals two more controls:

ControlRangeDefaultEffect
Star Rays1 – 63How many directions the star splits into
Star Angle0 – 360°Rotates the whole set of rays

Threshold

The default threshold of 0.5 mainly affects highlights. Lowering it includes more of the image; near 0, the entire face can glow

Threshold Smoothness sets how hard that cutoff is. At 0 a pixel that just crosses the line glows at full strength, which can make the boundary pop as brightness changes; raising it eases nearby pixels in, which holds up better in motion

Glowing Only Selected Colors

By default any sufficiently bright pixel glows. Switch Select Colors on and only pixels matching the colours you pick will — useful for isolating a neon sign, glowing eyes, or a single prop

The five slots are edited one at a time through Color Slot: pick the slot to configure, then set its switch and its colour

ControlRangeDefaultEffect

Color Tolerance0.01 – 10.5How far a colour may differ and still match
Color 1 – 5Hex#ffffffA colour that can produce glow
Use Color 1 – 5SwitchOnly 1 enabledWhether this slot takes part in matching

Color 1 is enabled by default on purpose: with all five off the mask is empty, so switching Select Colors on would make the glow vanish rather than narrow

Raising Color Tolerance brings in pixels further from the picked colours in saturation and brightness; at the low end it matches almost exact colours only

Processing Order

Bloom runs after chromatic aberration and before diffusion, so diffusion veils a frame that already carries the glow
