To adjust the softness of the vignette:
m Middle-click and drag to blur the edges of the vignette.
This adjusts the Softness parameter. The degree of softness is visualized in the Previews
tab with a pair of concentric circles. The inner circle shows where the edge blurring
begins, and the outer circle shows where the edge blurring ends, along with the shape.
Using a User Shape for Vignetting
The following procedure outlines how you use the User Shape option in the Shape
pop-up setting of the vignette controls.
1 Open the Secondaries room, click on one of the eight secondaries tabs to select which
secondary operator to work on, and then select the Enabled and Vignette checkboxes
to enable the vignette controls.
2 Choose User Shape from the Shape pop-up menu.
The Shapes tab of the Geometry room is immediately opened, with a new shape in the
shapes list to the right, ready for you to edit.
Animating Vignettes
One of the most common operations is to place an oval over someone’s face and
then either lighten the person, or darken everything else, to draw more attention to
the subject’s face. If the subject is standing still, this is easy, but if the subject starts to
shift around or move, you’ll need to animate the vignette using keyframes so that the
lighting effect follows the subject. For more information on keyframing, see
Chapter 14, “
Keyframing ,” on page 285.
Another option would be to use the motion tracker to automatically track the moving
subject, and then apply the analyzed motion to the vignette. For more information,
see “
Tracking Tab ” on page 306.
