Bloom
Bleed bright regions into a multi-scale glow with tight core and broad halo controls.
Add Bloom
Open an image or build the source composition first. Put this effect after the content it should process in stack processing order. Choose Optics → Light → Glow → Bloom in the effects picker, or search for Bloom with Cmd/Ctrl + F. Select the new layer in Layers to open its Effect Panel.
Select the light
Set Threshold to isolate the highlights that glow. Increase Radius for the halo size and Intensity for its brightness; Scales adds broader glow layers.
Balance the glow
Compare with the layer eye. Increase Intensity gradually and retain detail in bright areas. Use footer opacity or a mask to keep the treatment under control.
Set an individual colour
Click the relevant colour swatch to open its picker. Colors and Palettes explains colour values, transparency and the canvas sampling controls where available.
Compare and finish
Toggle the layer eye to compare with the incoming composition. Use the Effect Panel footer for opacity and blend mode, or add a mask to limit the affected area. In Video or Live, use the function menu on a supported control to add keyframes or a driver.
