Color Balancing with Hue and Gain
The two parameters used with color balancing are hue and gain. The value of
hue determines the color to add and the value of gain specifies the amount
of color to use.
To color balance with hue and gain:
Do one of the following:
Set the Hue and Gain fields by either dragging inside the field or
typing in a value.
Drag the center of the wheel. Repeat to set a different range (shadows,
midtones, or highlights) of colors.
Pure red is the 0-degree point for hue on the color wheel. When you increase
the hue value, you move counterclockwise on the color wheel. When you
decrease the hue, you move clockwise on the color wheel.
The center of the color wheel represents 0 gain. As you increase the value of
gain, you move towards the edge of the color wheel and add more of the
selected color to the image.
NOTE If saturation is set to 0, no color balancing is performed, regardless of the
gain value.
