The Color Balance node
The
Color Balance
node provides a control that is similar to the RGB Curves node
for grading, as shown in following screenshot. The difference is that since this node
has a color wheel for each of the Gain/Gamma/Lift components, its easier to man-
age color-based grading. The same process in the RGB Curves node would be a bit
complicated since curves have to be shaped separately for R, G, and B. However,
having a curve-based control in the RGB Curves node provides more precision in
grading in comparison to the
Color Balance
node.
The
Color Balance
and
RGB Curves
nodes can be used in combination to make
flows to have the desired grading control.
The Mix node
The
Mix
node blends a base image connected to the top image socket with a second
image connected to the bottom image socket based on the selected blending modes,
as shown in following screenshot. All individual pixels are mixed based on the mode
selected in this node. The Alpha and Z channels are also mixed.
