Chapter 7: Using Artist Color with Apple Color
This section describes the color correction process by examining important functions in some of the Apple color rooms (Primary
In, Secondary: Vignette Control, and Color FX).
Primary In
Contrast
Most colorists begin by correcting the contrast of an image before adjusting its color. Artist Color lets you adjust the Shadow, Mid-
tone, and Highlight contrast using the three Trackwheels as follows:
• To adjust
Shadow
, use the left Trackwheel;
• To adjust
Midtone
, use the middle Trackwheel;
• To adjust
Highlight
, use the right Trackwheel.
Contrast can be further adjusted by engaging Mouse Injection and changing the Luma curve control.
To change Luma curve:
1
Press the
Mouse Injection
Soft Key.
2
Press
R3
to left-click and create a control point.
3
Use the center Trackball to hover over a control point, then press and hold
R3
and use the Trackball to move the control point.
To adjust Master Lift, Master Gain, and Master Gamma controls in the Basic tab:
1
Press
Bank 1
.
2
Turn Soft Knobs 4–6 to control
Lift, Gain
and
Gamma
, respectively.
Color Balance
After correcting image contrast you can adjust the color balance. Fast, coarse adjustments to color balance (
Shadow, Midtone, and
Highlight
) can be made using the Trackballs to set the primary color balance, as follows:
• The left Trackball controls the
Shadow Color Balance
wheel;
R1
resets
Hue
and
Saturation
.
• The middle Trackball controls the
Midtone Color Balance
wheel;
R3
resets
Hue
and
Saturation
.
• The right Trackball controls the
Highlight Color Balance
wheel;
R5
resets
Hue
and
Saturation
.
More detailed adjustments can be made by engaging Mouse Injection to change the red, green, and blue curve(s). Numeric adjust-
ments can be made to the
Red, Green, and Blue Lift, Gamma,
and
Gain
controls by selecting
Bank 2
to go to the
Advanced
tab and
then turning the Soft Knobs.
Saturation
When the quality of the colors is satisfactory, the next step is to raise or lower the saturation (also called intensity) of the colors in
the image. Select
BANK 1
and use the Soft Knobs to adjust the
Saturation, Highlight Sat.
, and
Shadow Sat.
controls in the
Basic
tab.
This allows adjusting the overall saturation or only the saturation within specific tonal regions.
