HalHalcyon Days - Photoshop Halation Script

Saw this killer halation script.
Halcyon Days recreates the optical characteristics of analog film that digital sensors can't capture. The script adds customizable local halation—soft glows around individual highlights—plus an optional atmospheric global halation that wraps your entire image in a film-like veil. It boosts highlight chroma to preserve vibrant colors in bright areas and smooths chroma transitions for organic film-grain-like color blending. It's highly customizable, with 35mm and medium format presets for both color and black-and-white looks.
