If the Sharpen controls aren’t shown in the Adjustments inspector or the Adjustments pane of
the Inspector HUD, choose Sharpen from the Add Adjustment pop-up menu, and specify the
following settings:
•
To adjust the amount of sharpening applied to the image: Use the Intensity parameter controls.
Use the Intensity slider and
value slider to adjust the strength
of the sharpening adjustment.
Use the Radius slider and
value slider to adjust the area
over which the sharpening
adjustment is applied.
A value of 0.0 applies no sharpening adjustment to the image. A value greater than 0.0
increases the sharpening adjustment to the image.
•
To adjust the area over which the sharpening adjustment is applied (the distance, in pixels, that
Aperture goes from each pixel to evaluate sharpness): Use the Radius parameter controls.
A value of 0.0 applies no sharpening adjustment to the image. A value greater than 0.0
increases the area over which the sharpening adjustment is applied.
You can also brush the Sharpen adjustment on specific areas of an image. For more information,
see

Apply a vignette to an image
You use the Vignette adjustment controls to apply a vignette to an image. The term vignette
describes an image whose brightness fades to its periphery from its center. Vignettes are usually
applied to an image after it’s shot, for artistic effect. Aperture provides two types of vignettes:
Exposure and Gamma.
The Exposure vignette is designed to simulate a lens-created vignette.
