By selecting an area, you can perform selective color corrections. In each of these areas, you can
control the red, green and blue color channels and the brightness (luminance - gray bar).
Hue and Saturation
These two functions affect the entire image.
w Hue -
With this function you travel once around the entire color wheel either clockwise or
counter-clockwise (
“Color wheel and color vectors (vectorscope view)” on page 9-74).
To view the effect, try applying this function to the color bars test image. Each color grad-
ually changes to the color adjacent to it in the color wheel.
This function is especially important in the NTSC standard because it can be used to bal-
ance the color shifts typical of NTSC.
Value range: +/- 255.
w Saturation -
This function adjusts the colorfulness of the image from achromatic (black-and-white,
completely de-saturated) to very, very colorful (over-saturated).
Value range: +/- 255.
Using Color Correction
Color Correction is a primary color correction (as opposed to secondary or selective color correc-
tion). It is clip-based, meaning that modifications apply from a mark-in to a mark-out (no key
frames).
