Shadow & Highlight Recovery

Recovers detail in the darkest and brightest regions of an image — lifting blocked-up shadows and reining in blown-out highlights. The factors scale how strongly VIESUS corrects each region.

Parameters

Parameter	Section	Range	Default	Description
shadowfac	Lpars	0.0 – 1.0	0.5	Shadow region correction factor
highlightfac	Lpars	0.0 – 1.0	0.5	Highlight region correction factor

Recommended: Leave both factors at 0.5 — VIESUS already balances shadow and highlight detail automatically. Raise a factor for stronger recovery in that region, or lower it to keep more of the original tonal contrast.
