SUMMARY

Adobe Camera RAW (ACR) has quietly introduced a new "Glow" slider, designed to replicate the diffusion effect of vintage film lenses and diffusion filters. This tool spreads light from bright areas, creating effects ranging from subtle haze to cinematic bloom. The slider offers additional controls for light spread and allows selection of different glow types like halation and bloom, with an option to adjust warmth. It can be used within ACR's masking tools for selective application and aims to recreate the look often achieved by older lenses lacking modern flare-suppressing coatings.
