Bloom
Bleed bright regions into a multi-scale glow with tight core and broad halo controls.
Highlight Glow
Add source-aware highlight glow that stays focused around bright image structure.
Diffusion Glow
Apply a soft diffusion-filter haze that blooms highlights without fully washing out shadows.
Halation
Add warm red-orange bloom around bright edges, mimicking film halation and overexposed highlights.
