and value slider to

the contrast in the image. The contrast in the image is updated as you change the
parameter value.

Highlights & Shadows controls. For more information, see Working with the Highlights
& Shadows Controls.
Adjusting Definition in the Image
When you want to add a little clarity and definition to an image without adding too much
contrast, you use the Definition parameter controls. The Definition parameter is useful
for adding local contrast (adding contrast to areas of the image that are improved by a
contrast adjustment without affecting the image’s global contrast) as well as reducing
haze.
