Creating a primary color correction
Using RGB curves
¦NoteThe RGB Curves settings are available only with the advanced versions
of the Matrox primary and secondary color correction effects.
With RGB curves, you can individually adjust the red, green, and blue color
channels across the entire tonal range of your clip, or adjust all three color
channels simultaneously with a master curve. RGB curves allow you to achieve
color effects that would be difficult, if not impossible, to achieve using the
Color
Balance
settings, and also give you a high degree of control over the color
channels in each tonal range. For example, you can easily add a red, green, or
blue tint to your clip, or use the master curve as a way to adjust the brightness and
contrast of your clip.
Each curve is displayed on a grid with the horizontal axis representing the input
or current pixel value, and the vertical axis representing the output value of the
pixel after the curve adjustment is applied. By default, a curve starts as a straight
line with two end points, one at the bottom left of the grid (shadows), and the
other at the top right of the grid (highlights). Before any adjustments are made,
each point on the curve has the same input and output value.
