Apple Final Cut Pro 7 - Manual (Page 1366)

• Invert Selection button: Click this button to invert the key you’ve defined. For example,
if you’ve set up a key based on the color of a green car and turned the desaturation all
the way down so that the car is grayscale and the background is color, clicking the
Invert Selection button makes the background turn grayscale, and the car appears in
color.
Using Multiple Filters Together with the Limit Effect Controls
You can use the Limit Effect controls to layer multiple color correction filters onto a single
clip, selectively balancing specific areas of your picture based on their color, saturation,
and luma levels. Color correction filters work serially, the same as any other filters. This
means that if two color correction filters are applied to a single clip, the second color
correction filter works on the modified output of the first filter, rather than on the original
color values of the image.
For example, if you add a filter that adjusts the color in a group of flowers but causes the
green grass in the background to look too red, a second color correction filter using the
Limit Effect controls will target the greenish red color of the grass as it has been modified,
rather than the original green values.
The Color Corrector 3-Way Filter
The Color Corrector 3-way filter gives you more subtle control over the color of your clips
than the Color Corrector filter. The controls are deceptively easy considering the amount
of power they give you over the look of your clips. The main controls are at the top of
the visual interface tab—three color balance controls and level and saturation controls.
General Controls in the Color Corrector 3-Way Filter
There are several basic controls in the top-left corner of the filter.
