Qualifying a Color
Often you'll find a specific color in your clip can be enhanced, for example grass by the side
of a road, or the blue in a sky, or you may need to adjust color on a specific object to focus the
audience's attention on it. You can easily do this by using the HSL qualifier tool.
Using the HSL qualifier to select colors in your image is helpful when
you want to make areas of your image 'pop', to add contrast, or to
help draw the audience's attention to certain areas of your shot
To qualify a color:
1
Add a new serial node.
2 Open the 'qualifier' palette and make sure the 'selection range' picker tool is selected.
3 Click on the color in your clip you want to affect.
4 Usually you'll need to make some adjustments to soften the edges of your selection
and limit the region to only the desired color. Click on the 'highlight' button above the
viewer to see your selection.
5 Adjust the 'width' control in the 'hue' window to broaden or narrow your selection.
Experiment with the high, low and softness controls to see how to refine your selection.
Now you can make corrections to your selected color using the color wheels or custom curves.
Sometimes your selection can spill into areas of the shot you don't want to affect. You can easily
mask out the unwanted areas using a power window. Simply create a new window and shape it
to select only the area of color you want. If your selected color moves in the shot, you can use
the tracking feature to track your power window.

Adding a Power Window

Power windows are an extremely effective secondary color correction tool that can be used to
isolate specific regions of your clips. These regions don't have to be static, but can be tracked
to move with a camera pan, tilt or rotation, plus the movement of the region itself.
Use power windows to mask out areas you don't want
to be affected by the HSL qualifier secondary adjustments
