Color Calibration

Siril offers three ways to retrieve the colors of your image:

• Manual calibration

• Photometric Color Calibration, also called PCC.

• 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.

Tip

PCC and SPCC are two methods that require a plate-solved image. It is not possible to access these tools without this prerequisite.
