How to use Extract HSL from a JPG
- 1. Add the photo to map. Drop in the JPG whose color makeup you want to break apart. The tool converts every pixel from RGB into hue, saturation and lightness values.
- 2. Pick which component to view. Choose Component: Hue rendered as a color wheel, Saturation as an intensity map, or Lightness as a grayscale brightness map, each isolating one axis of the HSL model.
- 3. Download the component map. The tool renders the chosen component as its own image. Download it to study color distribution, debug a washed-out photo, or use the map as a mask in other editing software.
When to use Extract HSL from a JPG
Extract HSL from a JPG isolates the hue, saturation or lightness of a photo and renders that single component as its own image. It is aimed at anyone who wants to reason about color separately from brightness, which the RGB model bundles together.
- Diagnosing a washed-out or overly muted photo. A photo looks dull and you want to confirm whether it is a saturation problem or a lightness problem. Extracting Saturation as an intensity map shows exactly how vivid each area actually is.
- Building a hue-based mask for editing. You want to select only the greenish areas of a landscape photo in another editor. Extracting the Hue map as a color wheel view shows precisely which pixels fall in that range.
- Checking exposure independent of color. You want to evaluate a photo's brightness distribution without color getting in the way. Extracting Lightness gives a pure grayscale map that isolates exposure from hue and saturation.
- Teaching the HSL color model. You are explaining to a design student how HSL differs from RGB. Extracting all three components from one photo makes each axis visually obvious rather than abstract.
Examples
Lightness map
Input
photo.jpg + lightness
Output
photo.jpg as a grayscale lightness map
