Global Color Correction

Removes color casts and restores natural, balanced tones. These corrections are applied globally, across the entire image — as opposed to the targeted, per-zone adjustments in Local Color Correction.

Example

Original

Shot through a car window with a green cast

Before

Enhanced by VIESUS with ccstrength = 0.0

After

Enhanced by VIESUS with ccstrength = 0.5

Parameters

Parameter	Section	Range	Default	Description
ccstrength	Gpars	0.0 – 1.0	0.5	Automatic color correction strength
r	Gpars	-1.0 – 1.0	0.0	Manual red channel balance
g	Gpars	-1.0 – 1.0	0.0	Manual green channel balance
b	Gpars	-1.0 – 1.0	0.0	Manual blue channel balance
brightness	Gpars	-1.0 – 1.0	0.0	Manual global brightness adjustment
contrast	Gpars	-1.0 – 1.0	0.0	Manual global contrast adjustment
saturation	Gpars	-1.0 – 1.0	0.0	Manual global saturation adjustment

The manual channel and tone adjustments (r, g, b, brightness, contrast, saturation) are static and applied at the end of automatic processing, regardless of the analysis result. Adjust carefully — they can override otherwise correct automatic behavior. ccstrength is automatic and not affected.

Recommended: Keep ccstrength at default with Base Enhancement on. Reduce it for images that should retain a deliberate color cast.
