Luma Qualification Controls
The Luma Qualifier mode simply pulls a key from the Luma channel all by itself. It’s identical to
the HSL qualifier with H and S turned off. This single-component keyer is more useful than you
might think; it’s a common technique to isolate a range of highlights, midtones, or shadows
throughout the image to alter the color temperature selectively.
The Luma Keyer mode automatically disables the Hue and Saturation controls
Also, keep in mind that the luma component is the sharpest keyable component when youre
working with heavily compressed video. Keys that are noisy or chunky with HSL qualification
may be sharper if you just use the Luma Qualifier, although you won’t be able to be
chromatically specific.
The Luma Qualifier has four parameters:
Lum Low/High: Two parameters let you define the upper and lower range of the luma
component being isolated.
Lum Low Soft/High Soft: Two parameters let you define the upper and lower softness
falling off outside the current range of luma.
3D Keyer Controls
As discussed earlier in this chapter, the 3D Keyer works much differently than the other
qualifiers in DaVinci Resolve. In this mode, drawing lines over parts of the image you want to
isolate adds samples to the Sample list, some of which add to the key (when you drag with the
pointer) and some of which subtract from the key (when you Option-drag with the pointer).
While this functionality is very simple to use, there are other controls that are available.
