Auto Level Controls in the Color Corrector 3-Way Filter
Using the Auto Level controls and the Whites, Mids, and Blacks sliders to maximize the
contrast of your image is usually the first step you take when color correcting a clip.
 Auto White Level button: Click this button to analyze your clip and find the maximum
level of white in the frame. The Whites slider is then adjusted to move the maximum
white level to 100 percent as viewed in the Histogram.
 Auto Black Level button: Click this button to analyze your clip and find the maximum
level of black in the frame. The Blacks slider is then adjusted to move the maximum
black level of your clip to 0 percent as viewed in the Histogram.
 Auto Contrast button: Click this button to perform the functions of both the Auto
White Level and Auto Black Level buttons simultaneously.
Using a Trackball with the Color Correction Filters
Additional keyboard shortcuts are available to make it easy to use a trackball to adjust
the color balance controls in the Color Corrector and Color Corrector 3-way filters. These
keyboard shortcuts work only while the mouse button (or trackball button) is pressed,
and are designed to work with the drag lock button of your trackball.
Tip: When you press the drag lock button of your trackball, the trackball button remains
pressed and continuous adjustments can be made to the color balance controls.
To work with the color balance controls while the drag lock mode of your trackball is
enabled, press Tab to move from one color balance control to the next.
If your trackball has multiple programmable buttons, you can map three other
keyboard shortcuts to them to go directly to specific color balance controls.
 Option-Control-8: Selects the Blacks control.
 Option-Control-9: Selects the Mids control.
 Option-Control-0: Selects the Whites control.
