The Vibrancy slider increases (or decreases)

increasing (or decreasing) the saturation of
other colors. This means that some yellow and
orange tones are less affected by adjusting
the Vibrancy slider, while the blues and greens
will be noticeably modified, as shown in
Figure 6.21. You can take advantage of the
Vibrancy slider not only with photos of peo-

increase or decrease the saturation of the
greens and blues while having less impact on

the wheel and click the corresponding pixels
