HSL Secondary Keying for Rescue

color correction technique used to salvage poorly shot green screen footage by targeting a very specific color range. It involves using the HSL (Hue, Saturation, Luminance) secondary controls within a color tool to isolate the specific green of the screen, even when it's uneven or spills onto the subject. This allows for a cleaner key than a standard chroma keyer might achieve and is a critical problem-solving method when reshoots are not an option.
