Lesson 13
Making Secondary Adjustments
the best option is to use a Power Window to limit which part of the frame the qualifier
operates on. For instance, in our shot you may notice her lips still showing a bit of color.
Instead of fiddling with the Qualifier which would affect the scarf selection, you’ll use a
window to mask out everything except the scarf.
1 Select node 02 in the node editor.
2 In the toolbar, in the central palettes, click the window palette icon
3 In the list of Power Windows, click the curve button to activate it.
4 Double-click next to the curve button, and label the window as SCARF.
5 Move your mouse pointer into the viewer and make sure you can see the entire frame.
Now you are ready to draw a custom window shape.
6 Draw a shape by loosely clicking around the scarf, starting at the bottom of her chin,
up to the dark left side of the face, down to include the dark part of the scarf, off the
screen at the bottom of the scarf and finally up around the right side of the scarf.
