The Vibrance in Lightroom saturates the colors that are unsaturated. It’s different from the saturation which saturates all the colors.

This photos is part of my project on the cats and dogs of the “Downtown East Side”.

Here’s the before the vibrance and after the vibrance. The before is not the Lightroom default, everything is set to 0. The exposure, the recovery, the fill, the blacks, the brightness the contrast… Everything is set to 0.

Before — Everything 0 Vibrance 100
Lightroom: Everything set to 0 Lightroom: Vibrance set to 100
Lightroom: Everything set to 0 Lightroom: Vibrance set to 100

Look at how much the color of her skin, her hair, and the green ring on her finger have changed, but the black/grey of the jacket is almost the same.

I didn’t use the Before/After because the before is the left half or the photo, while the after is the right half of the photo.
