cursor around in the area of the grass to select it. You'll notice in
the Qualification tab that the HSL bars show the selected color vec-
tor of the grass, defined by white lines in the bars ( Figure 12.25 ).

the Highlight checkbox in the Qualifier tab. The default is to show
the selected area in the viewer as a color (green for grass) and
all nonqualified or nonselected colors are shown as gray. My
selection picked up on some of the green cast of the pillars in
the building, which I don't want. So use the Low sat and High
Luma controls to try to dial in a better selection, or use the “-”
button to the right of the eyedropper control and click in the
areas you want to subtract from the selection. If you like a nice
high-contrast key to see your selection, go to the Config screen
in the Settings tab and check the box for “Mattes display high
contrast black and white” ( Figure 12.26 ).Without the hi-con
matte option, the qualification looks like Figure 12.27 in the
viewer. With the hi-con matte option, the qualification looks like
Figure 12.28 in the viewer. Use whichever one helps you make
the best qualification.
To make the best adjustment of this qualification, turn off the
checkbox for Highlight in the Qualifier tab so that you are view-
