286 Chapter 10 COLOR CORRECTION yellows in the scarf without affecting any other colors in the image. The Symphony Secondaries provide two different types of vec- tors: standard and custom. Standard vectors allow you to select a range of hue and specify a minimum saturation. They look like pie wedges. Custom vectors allow you to select a range of both hue and saturation and look like ellipses with the defined hue and saturation ranges used as the two axes of the ellipse. You define them by specifying a midpoint for both hue and saturation then a range for each. Conclusion As you can see, the color corrector in both Media Composer and Symphony is incredibly sophisticated and powerful. A full exploration of the color corrector is worth its own book, but hope- fully we've provided you with a primer that can get you started with these powerful tools.
