Vibrancy and Saturation controls

[DarkPenguin]

On some images I like to use - vibrancy and + saturation.  (Sometimes in the extreme.  Like -90 and +100.)

I know what + saturation does but what exactly is - vibrancy doing?

My understanding is that the vibrance control is the same as the saturation control except that it only affects the primary colors where saturation affects all colors.

Jeff explains it on one of the videos (too lazy to find it) but IIRC the Sat slider is linear and boosts all colors... the vibrance slider is non-linear and boosts the less saturated colors more the the more saturated colors.

Right, with the added  benefit of skin tone protection.

So when you're going negative with it it still protects skin tones?  (Can you select the race?)  Does it desaturated the saturated more or less?

Edit:  I should probably just run a test chart of some sort through it and see what it does.

"Caucasian" skin tones only.
