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
For example, you can track a window on a person in order to make color and contrast changes
just to that person without affecting his or her surroundings. By making corrections like this you
can influence the audience's attention on areas you want them to look at.
To add a power window to your clip:
1
Add a new serial node.
2
Open the 'window' palette and select a window shape by clicking on a shape icon.
Your selected window shape will appear on the node.
3
Resize the shape by clicking and dragging the blue points around the shape. The red
points adjust the edge softness. You can position the shape by clicking the center
point and moving it to the area you want to isolate. Rotate the window using the point
connected to the center.
Now you can make color corrections to your image in just the area you want.
