If the edges of the foreground subject are too sharp, use the Edges tool to soften the
foreground edges. The Edges tool is also effective for fine-tuning semitransparent features
such as smoke, glass reflections, and shadows.
5 In the Filters Inspector or HUD, click to select the Edges tool.
6 In the Canvas, drag a line over the edge of the foreground subject so one end point lies
in the interior of the foreground subject and the other end point lies in the background
(the orange sky).
An Edges control line appears in the Canvas.
7 In the Canvas, drag the center handle of the Edges control line to adjust the edge
transparency of the keyed subject.
You can also set the View mode to Matte, which helps you see the effect of using the
Edges tool. (The Matte mode also helps you review your work when you modify the Fill
Holes and Edge Distance parameters.)
Tip: If you open the Color Selection controls while dragging the center handle, you can
see how the Edges control alters the outer softness graph of the Chroma control and the
bottom softness handles of the Luma controls.
When manually sampling colors to create a key, it’s not necessary to click the Sample
Color and Edges tools in the Inspector or HUD before you drag in the Canvas. Instead,
you can use keyboard shortcuts to activate the Sample Color and Edges tools while
dragging in the Canvas.
To add Sample Color and Edges controls in the Canvas using keyboard shortcuts
1 In the Layers list, select the Keyer filter to adjust.
2 Do one of the following:
• To create a Sample Color selection box, hold down the Shift key while dragging over
the color you want to key in the Canvas.
• To create a Edges sampling control, hold down the Command key while dragging to
draw a line that crosses over the edge of the subject you’re keying in the Canvas.
• To remove a Sample Color or Edges control, Option-click anywhere in the control you
want to delete, or click to select a sample control, then press the Delete key.
