Working with the Vignette Controls
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 is shot, for artistic effect. Aperture
provides two types of vignettes: Exposure and Gamma. The Exposure vignette is designed
to simulate a lens-created vignette. The Gamma vignette is designed for artistic effect
and applies a gamma adjustment to the affected pixels within the vignette. Because the
Gamma vignette intensifies the affected pixels, it creates a more pronounced vignette
effect than the Exposure vignette.
Note: You can add a vignette to any image cropped in Aperture. The adjustment is applied
after the image is cropped.
Applying an Exposure Vignette
You use the Exposure vignette when you want to apply the effect of a traditional
lens-created vignette.
