418 Part III Performing Image Adjustments
To adjust the contrast in an image:
1 Select an image.
2 In the Enhance area of the Adjustments inspector or the Adjustments pane of the
Inspector HUD, adjust the Contrast parameter by doing one of the following:
 Drag the Contrast slider.
 Click the left or right arrow in the Contrast value slider to change the contrast of the
image by 5 percent increments, or drag in the value field.
 Double-click the number in the Contrast value slider, then enter a value from
–1.00 to 1.00 and press Return.
A value below 0.0 decreases the contrast in the image. A value greater than 0.0
increases the contrast in the image. The contrast in the image updates as you change
the parameter value.
Note: If you’re trying to retrieve detail in a high-contrast image, you should use the
Highlights & Shadows controls. For more information, see “
Working with the Highlights
& Shadows Controls ” on page 435.
Use the Contrast slider
and value slider to
modify the contrast
between light and dark
colors in the image.
