Secondaries
The secondary curves use B-Splines, just like the primary curve controls. In fact, you
add and edit control points on the secondary curves in exactly the same way. For more
information, see “
Editing Control Points and B-Splines
Important:
The adjustments that are made using the secondary curves always affect
the keyframed hues throughout the entire frame, and are not limited with the Vignette
or HSL controls.
Hue Curve Tab
When you raise or lower part of the secondary hue curve, you make a hue adjustment
similar to that you make when you use the Global Hue control, except that you only
rotate the hue value for the selected range of hue specified by the curve. Raising the
curve shifts the values toward red, while lowering the curve shifts the values toward blue.
This control can be valuable for making narrow, shallow adjustments to the reddish/
orange section of the spectrum that affects skin tones, in order to quickly and smoothly
add or remove warmth.
