Histogram Select
Histogram Select
Use Histogram Select to pick a narrow value band around a chosen center. It is commonly used to isolate material features for selective blending.
Availability
This node requires Pro.
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 |
|---|---|---|---|
| Position | float | 0.5 | 0 to 1 |
| Range | float | 0.5 | 0 to 1 |
| Contrast | float | 0 | 0 to 1 |
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.
