3 In the Viewer, position the eyedropper on a color in the image that you want to isolate, and drag
to select the color.
Drag to select the
color to mask.
As you drag, two concentric circles appear. The size of the outer circle determines the range of
variations in the selected color that are included in the color mask. As you change the outer
circle size, the image becomes monochrome except for the color you are selecting. You can drag
a new selection circle as many times as you like to try for better results.
Note: When you stop dragging, the picture returns to its original look, but you’ll see the effects
of the color mask you have created as soon as you start making adjustments in the Color Board.
You can then return to the Video inspector and use the eyedropper to make any adjustments to
the color mask.
4 To change the range of color variations included in the mask, do either of the following:
•
To add color shades: Hold down the Shift key, position the eyedropper on a color you want to
add to the mask, and drag to select the color.
•
To subtract color shades: Hold down the Option key, position the eyedropper on a color you
want to remove from the mask, and drag to select the color.
5 To adjust the color mask edges, drag the Softness slider.
To have the Viewer temporarily show the color mask, hold down the Option key and then drag
the Softness control: white indicates fully opaque mask areas, black indicates areas outside the
mask, and levels of gray indicate transparent mask areas.
