Halation

Bloom reds and brights the way film emulsion blooms around highlights.

Halation is the red bloom around bright highlights on film, caused by light scattering in the emulsion or reflecting from the base. Older stocks and certain cine films showed it strongly; modern films often add anti-halation layers to suppress it.

As a look it softens speculars and gives night scenes a romantic bleed. Push it on streetlights and windows.
