Using with other options
You can combine saturation with other tone controls (e.g., brightness, hue) for finer adjustments.
Pushing saturation too high can make skin tones look unnatural or cause color bleeding, so it’s best to adjust gradually—typically around 1.05–1.2.
Lowering saturation can create a more subdued mood, and unlike grayscale, it still preserves color information.
