Калибровка цвета
Siril offers three ways to retrieve the colors of your image:
Фотометрическая калибровка цвета, или ФКЦ.
Spectrophotometric Color Calibration, also called SPCC. This is the most accurate and recommended method
Here, "retrieve" means re-balancing the RGB channels to get as close as possible to the true colors of the shot object.
Совет
PCC and SPCC are two methods that require a plate-solved image. It is not possible to access these tools without this prerequisite.
