Adjusting Denition in the Image
When you want to add a little clarity and denition to an image without adding too much
contrast, you use the Denition parameter controls. The Denition parameter is useful for adding
local contrast (adding contrast to areas of the image that are improved by a contrast adjustment
without aecting the image’s global contrast) as well as reducing haze.

To adjust denition 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 Denition parameter by doing one of the following:
•
Drag the Denition slider.
•
Click the left or right arrow in the Denition value slider to change the clarity of the image by
5 percent increments, or drag in the value eld.
•
Double-click the number in the Denition value slider, then enter a value from 0.0 to 1.0 and
press Return.
Use the Definition slider
and value slider to add
local contrast to the photo.
A value greater than 0.0 increases the clarity in the image. The denition in the image is updated
as you change the parameter value.
