New RGB HSL Decomposition!
Want to match other photos' styles? One of the easiest ways to do this is to utilize an HSL decomposition and match hue, saturation, and luminance individually in a photo. Using this Photoshop action, you can decompose your RGB photo into these separate layers for fine-tuned editing.
This is a single Photoshop action to decompose your RGB image into Hue, Saturation, and Luminance layers. Install the action by putting it into your Actions Presets folder.
