Nodo Derrame de color¶
The Color Spill node is used to suppress unwanted color casts—typically green or blue; caused by light reflecting from a chroma key (green or blue screen) onto the subject.
This «spill» is common in compositing workflows and can give a subject an unnatural colored tint. The node reduces the influence of the selected color channel, removing the excess and restoring a more natural appearance.
Entradas¶
- Imagen
The input RGBA image to be processed.
- Fac
Blend factor for how strongly the node affects the image. A value of 1.0 fully applies the effect; lower values blend with the original.
- Limit Strength
Specifies the limiting strength of the limit channel.
Spill Strength¶
If enabled, the spill strength for each color channel can be specified. If disabled, the spill channel will have a unit scale, while other channels will be zero.
- Intensidad
Specifics the spilling strength of each color channel.
Propiedades¶
- Suprimir derrame de canal
Permitirá seleccionar qué canal reducir:
- R:
Suprimir derrame de rojo.
- V:
Suppress green spill (common for green screens).
- A:
Suppress blue spill (common for blue screens).
- Algoritmo
Chooses the method for spill reduction:
- Simple:
Compares the Limiting Channel channel to the others and reduces it if it is higher.
- Promedio:
Uses the average of the other two channels to set the limit for the despill channel.
- Limiting Channel Simple
When using the Simple algorithm, you can choose which channel(s) to use as a reference for limiting:
- R:
Use red as the reference.
- V:
Use green as the reference.
- A:
Use blue as the reference.
