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.

To apply an Exposure 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 Adjustments pop-up menu (or press Control-V).

  3. Choose Exposure from the Type pop-up menu.

  4. Adjust the amount of vignette to apply to the image by doing one of the following:

    • Drag the Intensity slider to the left to decrease the amount of dark shading applied to the edges of the image, or drag the slider to the right to increase the dark shading.

    • Click the left or right arrow in the Intensity value slider to change the amount of dark shading applied to the edges of the image, or drag in the value field.

      The left arrow decreases the amount of dark shading applied to the edges of the image, and the right arrow increases the dark shading.

    • Double-click the number in the Intensity value slider, then enter a value from 0.0 to 1.0 and press Return.

  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 Radius 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 the slider to the left to limit the vignette to the edges of the image.

    • Click the left or right arrow in the Radius 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 Radius value slider, then enter a value from 0.0 to 2.0 and press Return.

      Figure. Radius controls in the Vignette area of the Adjustments inspector.

The Exposure vignette is applied to the image.

You can also brush the Exposure Vignette adjustment on selected parts of an image. For more information, see Making Brushed Adjustments.

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 Adjustments pop-up menu (or press Control-V).

  3. Choose Gamma from the Type pop-up menu.

  4. Adjust the amount of vignette to apply to the image by doing one of the following:

    • Drag the Intensity slider to the left to decrease the amount of dark shading applied to the edges of the image, or drag the slider to the right to increase the dark shading.

    • Click the left or right arrow in the Intensity value slider to change the amount of dark shading applied to the edges of the image, or drag in the value field.

      The left arrow decreases the amount of dark shading applied to the edges of the image, and the right arrow increases the dark shading.

    • Double-click the number in the Intensity value slider, then enter a value from 0.0 to 1.0 and press Return.

      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 Radius value slider, then enter a value from 0.0 to 2.0 and press Return.

The Gamma vignette is applied to the image.

You can also brush the Gamma Vignette adjustment on selected parts of an image. For more information, see Making Brushed Adjustments.

For information about removing a vignette that was applied to an image when it was shot, see Working with the Devignette Controls.

Switching Vignette Types

You can switch the type of vignette that’s applied to an image and maintain the Intensity and Radius parameter values you set using the previous vignette type.

To switch vignette types
  • Choose the other vignette type from the Type pop-up menu.

The new vignette is applied to the image, but the Intensity and Radius parameters maintain their settings.
