210 Chapter 10 Secondaries
 Isolating areas for targeted corrections: This is the primary reason for the Secondaries
room’s existence. Using a variety of techniques, you can perform functions such as
isolating the highlights in an image to change the quality of light, target the color of
an overly bright sweater to desaturate it without affecting the rest of the image, or
select an actor’s face to create a post-production sunburn. Once you master the
ability to selectively adjust portions of the image, the possibilities are endless.
 Creating vignetting effects: Traditionally, vignettes used for creative purposes describe
a darkening around the edges of the image that used to be created with mattes or
lens filters. You can create any type of vignette you need using either preset or
custom shapes, to darken or otherwise flag areas of the image. Vignettes can be used
to focus viewer attention by highlighting a subject in the foreground or by shading
background features that you don’t want sticking out.
