Balanço de cor¶

The Color Balance node adjusts the color and values of an image.

Inputs¶

Fator: Controls the amount of influence the node exerts on the output image.
Color: Standard color input.

Properties¶

Correction Formula

The mathematical method to adjust the image’s colors.

Realce, gama e ganho:

Adjusts the colors and tonal range of an image by controlling the shadows, midtones, and highlights separately.

Realce: Adjusts the darkest areas of the image (the shadows).
Gama: Primarily affects the midtones, the middle range of brightness in the image.
Ganho: Controls the brightest parts of the image (the highlights).

Deslocamento, potência e inclinação (ASC-CDL):

A standardized model for adjusting the colors and tonal range of an image. This allows the same values to be used across different application to yield the same result. See Advanced for more details on the underlying implementation.

Deslocamento: Adjusts the darkest areas of the image (the shadows).
Basis: Additional offset, allows to specify a negative offset value.
Potência: Primarily affects the midtones, the middle range of brightness in the image.
Inclinação: Controls the brightest parts of the image (the highlights).

Ponto do branco:

Adjusts the color that should be considered white. The white point is specified as setting the inputs color temperature and then the desired output temperature.

Temperatura: The blackbody temperature of the primary illuminant. By default a D65 white point is used.
Tint: The amount of green/magenta shift of the blackbody curve.

Saídas¶

Color: A saída em formato de imagem padrão.

Avançado¶

The Offset/Power/Slope Formula¶

\(\text{out} = (i \times s + o)^p\)

onde:

saída: O valor das cores de pixeis após a graduação.
e: o valor de código do pixel de entrada (de 0 a 1) (do preto ao branco).
i: Inclinação (qualquer número de 0 a maiores, o valor nominal é 1.0).
d: Deslocamento (qualquer número, o valor nominal é 0).
p: Potência (qualquer número maior que 0, o valor nominal é 1.0).
