Blackmagic Design DaVinci Resolve Advanced Panel - Manual (Page 258)

COLOR 258
YSFX Sliders
Each of the Custom curves (Y’, R, G, and B) has a vertical YSFX slider at the right of each curve control
that lets you invert any or all color channels, to create different types of special effects.
As with all other adjustments in the Color page, YSFX may be combined with Power Windows or HSL
qualification to limit channel inversions to specific portions of the image for creative effect.
Adjusting Custom Curves with the DaVinci Resolve Control
Surface
The controls that correspond to the Custom curves on the DaVinci Resolve control surface are available
by default when you first open Resolve and the rotary knobs on the center panel will be labeled
PRIMARIES. If these buttons are not visible, you need to switch to the Primaries controls using the
display buttons.
