Color Correct
Description
Color Correct manipulates hue, saturation, brightness, contrast, gamma, temperature, cyan/magenta, red, green and blue values of the overall image and separately in user definable shadow, midtone and highlight areas. In addition to traditional slider controls, a visual Color Wheels interface can be used to make adjustments.

Master, Shadows, Midtones, Highlights
All of the color correctors can adjust an image by using it’s master, shadows, midtones and highlight groups. The master settings affect the entire image while adjusting parameters within the shadows, midtones and highlights will only affect those specific areas.
If you are unsure about what values are included in the shadows, midtones and highlights, you can use the View pop-up menu. It will allow you to view the shadows, midtones and highlights as a black and white matte. The white areas are the areas that will be adjusted by that particular group. For instance, if you see white areas while viewing the midtones, then midtone color adjustments will affect only those white areas. If you want to change the default areas defined by the shadows, midtones and highlights, you would use the Position and Range sliders.
Position
The Position slider pinpoints the values to be considered as shadows, midtones, or highlights. A low Position value uses the darkest image values, while a high Position value uses the brightest.
Range
Increases or decreases the range of values considered as shadows, midtones or highlights. A low Range value indicates a narrow range of values, while a high Range value indicates a large range of values.
Go to the Matte section of Common Filter Controls to see how the Position and Range controls work.
