User Manual

Finally, each group of Lift/Gamma/Gain sliders has its own reset button. To reset individual
channels, double-click the single-letter label underneath that slider.
To adjust RGB Lift/Gamma/Gain using the DaVinci control surface:
1 Press the POTS soft key on the main page of the Center panel.
2 Use the variously identified LUM/RED/GREEN/BLUE and OFFSET/BLACK/GAMMA/
GAIN knobs to make the required adjustments.
3 Press the MAIN soft key to return to the Center panel’s main page.
Offset Sliders, Offset Wheel, and Printer Points
These vertical sliders mirror the settings of the Offset color balance controls in the Color Wheel
palette, except that they provide individual control over the Red, Green, and Blue color
channels. When you drag one of the Offset sliders up or down, you raise or lower that color
channel in its entirety, which can be useful for adjusting color channels that are particularly
problematic, or for imposing the kind of traditional linear color adjustments that color timers of
film have employed for decades. In fact, many colorists consider the simplicity of these controls
a virtue, and embrace the slight shadow or highlight contamination that can result from color
balancing in this linear way as a creative hallmark of traditional cinema color adjustment.
Offset RGB and master controls
NOTE: Unlike the other Color Wheels control adjustments described in this chapter,
the Offset controls do not use the Lum Mix parameter to control whether individual
adjustments to the R, G, or B channels result in automatic adjustments being made to
the other two color channels in order to maintain constant Luma levels. All Offset and
printer points adjustments made to a specific color channel affect only that
color channel.
Adjusting Printer Points in the Primaries Bars Palette
Each Offset slider also has a pair of arrow buttons, one at the top and one at the bottom. These
buttons provide “Printer Point” adjustment of these values, which let you adjust each Offset
channel in discrete increments. Printer Points can be useful for projects that have tight
integration with a film lab, and are designed to emulate color adjustments made using
optical printers.
