Operation Manual

Note: When you apply a Devignette and Crop adjustment to the same image, Aperture
applies the Devignette adjustment prior to the crop in order to correct lens artifacts.
Applying the Devignette adjustment before the crop prevents any distortion that would
otherwise appear in the cropped image.

one of the following:
• Drag the Intensity slider to the left to decrease the amount of brightness applied to
the edges of the image, or drag it to the right to increase the brightness.
• Click the left or right arrow in the Intensity value slider to change the brightness applied
to the edges of the image, or drag in the value field.
The left arrow decreases the amount of brightness applied to the edges of the image,
and the right arrow increases the brightness.
• Double-click the number in the Intensity value slider, then enter a value from 0.0 to 1.0
and press Return.
Use the Intensity slider and value
slider to adjust the amount of
brightness applied to the edges
of the image.
4 To adjust the distance Aperture goes from the edge of the image, in pixels, to apply the
Devignette adjustment, do one of the following:
• Drag the Radius slider to the right to increase the number of pixels Aperture goes
toward the center of the image to apply the Devignette adjustment, or drag it to the
left to limit the vignette to the edges of the image.
