Saturation≠Saturation
Added 2021-08-26 16:15:43 +0000 UTCAffinity Photo shows an interesting behavior, when using the Saturation from the "Vibrance Adjustment" compared to the "HSL Adjustment". It seems that the Saturation in the "Vibrance Adjustment" is still within the purpose of what Vibrance does, while in the HSL Adjustment, it simply changes the Saturation Value of the Colors. (I altered to look of the HSL Adjustment Window, so you can see the Gradient in the back better)
According to this page "The main difference between the Vibrance and Saturation sliders is that Vibrance only affects the less saturated colors of an image; colors and pixels that already are saturated are less affected, which means that it’s less likely to blow out any colors." https://www.capturelandscapes.com/saturation-vs-vibrance-whats-the-difference/
It's interesting to notice that in Lightroom Vibrance and Saturation act in a different way too. However, here Vibrance protects skin tones, while Saturation affects blue tones differently. See the image below:
Look specifically at the rainbow gradient and how the orange in the Vibrance is less affected, while the Blue in the Saturation is less affected. This also works in the other direction, where the Blue of the eye and especially the blue sky in the eye reflection are a lot more affected by Vibrance than by Saturation in Lightroom.
According to this Source: "The difference between vibrance and saturation in Lightroom is that vibrance detects highly saturated portions of the scene, as well as skin tones, and protects them while increasing the saturation on the rest of the image. It’s smart."
