Adjusting Vibrancy in the Image
You use the Vibrancy parameter controls when you want to add a bit of punch to the image
without aecting skin tones. The Vibrancy parameter applies saturation to the image in a
nonlinear manner. Colors that are already saturated are left alone, while saturation is added to
all other colors. In addition, the Vibrancy parameter takes skin tones into account, leaving them
untouched. This allows you to take a portrait and desaturate the image except for the skin tones.

To adjust vibrancy in an image
1 Select a photo.
2 In the Enhance area of the Adjustments inspector or the Adjustments pane of the Inspector HUD,
adjust the Vibrancy parameter by doing one of the following:
•
Drag the Vibrancy slider.
•
Click the left or right arrow in the Vibrancy value slider to change the saturation of the image
by 5 percent increments, or drag in the value eld.
•
Double-click the number in the Vibrancy value slider, then enter a value from –1.0 to 1.0 and
press Return.
Use the Vibrancy slider and
value slider to add smart
saturation to the photo.
A value below 0.0 decreases the color saturation in the image, and a value above 0.0 increases
the saturation of the nonsaturated colors. A value of –1.0 removes all color from the image,
making it grayscale except for any skin tones.
