5 To adjust the distance Aperture goes from the edge of the image, in pixels, to apply the
vignette adjustment, do one of the following:
 Drag the Size slider to the right to increase the number of pixels Aperture goes
toward the center of the image to apply the vignette adjustment, or drag it to the
left to limit the vignette to the edges of the image.
 Click the left or right arrow in the Size value slider, or drag in the value field.
The left arrow limits the vignette adjustment to the edges of the image, and the right
arrow moves the vignette adjustment toward the center point of the image.
 Double-click the number in the Size value slider, then enter a value from 0.0 to 2.00
and press Return.
The Exposure vignette is applied to the image.
Applying a Gamma Vignette
A Gamma vignette is an artistic adjustment that intensifies colors in the pixels affected
by the vignette.
To apply a Gamma vignette to an image:
1 Select an image.
2 If the Vignette controls are not shown in the Adjustments inspector or the Adjustments
pane of the Inspector HUD, choose Vignette from the Add Adjustments pop-up menu.
3 Choose Gamma from the Type pop-up menu.
Use the Size slider and
value slider to adjust the
size of the area over
which the vignette
adjustment is applied.
