Apple Aperture 2 - Manual (Page 438)

438 Part III Performing Image Adjustments
To adjust the shadows in an image:
1 Select an image.
2 In the Highlights & Shadows area of the Adjustments inspector or the Adjustments pane
of the Inspector HUD, adjust the Shadows parameter by doing one of the following:
 By default, the Shadows slider is set to the left side of the slider control. Drag the
slider to the right to lighten the shadow areas of the image, and drag the slider back
to the left to reduce the lightening effect in the shadows.
 Click the left or right arrow in the Shadows value slider to change the brightness of
the shadows in the image by single increments, or drag in the value field.
The left arrow reduces the lightening effect in the shadows, making them darker. The
right arrow increases the lightening effect in the shadows, making them lighter.
 By default, the Shadows value slider is set to 0.0. Double-click the number in the
value slider, then enter a value from 0.0 to 100.0 and press Return.
Aperture isolates the shadow areas of the image and updates them as you change the
parameter value.
