HSL Adjustment
HSL Adjustment
Use HSL Adjustment for fast hue, saturation, and lightness correction without rebuilding upstream content. It is ideal for palette iteration and final artistic tuning.
Availability
This node is available in the free feature set.
Common uses
- Place channel nodes after generators and before final output shaping.
- Use histogram and levels tools to isolate useful ranges for masks.
Input ports
-
input -
Usually expects one image input, with optional secondary inputs for some nodes.
Output ports
-
out -
Outputs modified image or channel data for downstream processing.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Hue | float | 0 | -180 to 180 |
| Saturation | float | 1 | 0 to 2 |
| Lightness | float | 1 | 0 to 2 |
Behavior
- These nodes remap values rather than creating major new structure.
- Channel operations are useful for converting outputs into mask-friendly ranges.
Common mistakes
- Stacking many remap nodes can flatten contrast unexpectedly.
- Watch channel assumptions when mixing grayscale and RGBA signals.
