User Manual

Above the three trackballs are three buttons for resetting the grade:
 RGB: This key only resets the RGB balance to default detent.
 All: Select All to reset both RGB and level.
 Level: Select the Level key to reset the level while maintaining RGB differential.
Log, Offset, Viewer, and Trackball reset buttons
Control Knobs
The top of the panel features 12 high resolution endless turn optical encoder control knobs with
detent resets. These are spaced in groups of three for fast operation in dark suites. From left to
right the knobs control:
 Y Lift: This knob is for adjusting the contrast of the image in the darker areas. The
midtone and to a lesser amount the brighter areas of an image will also change.
 Y Gamma: Use the gamma knob for primarily mid tone contrast changes with some
influence on the darker and brighter sections.
 Y Gain: The Y Gain control influences the brighter parts of the image at a greater extent
to the mid and darker portions.
 Contrast: This one parameter lets you increase or reduce the distance between the
darkest and lightest values of an image, raising or lowering image contrast. The effect
is similar to using the Lift and Gain master controls to make simultaneous opposing
adjustments.
 Contrast Pivot: Changes the center of tonality about which dark and bright parts of the
image are stretched or narrowed during a contrast adjustment.
 Midtone Detail: When this parameter is raised, the contrast of regions of the image with
high edge detail is raised to increase the perception of image sharpness, sometimes
referred to as definition. When lowered to a negative value, regions of the image with
low amounts of detail are softened while areas of high detail are left alone.
 Color Boost: Lets you naturalistically raise the saturation of regions of low saturation,
sometimes referred to as a vibrance operation. Can be used also to lower the
saturation of regions of low saturation.
 Shadow: Lets you selectively lighten or darken shadow detail. Raising this value
retrieves shadow detail recorded below 0 percent, while leaving the midtones alone. 0
is unity.
