Feathering the edges of a mask
The mask looks good, but you need to soften the edges a bit.
- Choose Composition > Composition Settings.
Click the Background Color box, and choose white for the background color (R=255, G=255, B=255). Then click OK to close the Color Picker, and OK again to close the Composition Settings dialog box.
The white background allows you to see that the edge of the monitor screen looks a little too sharp and unrealistic. To address this, you’ll feather, or soften, the edges.
- Select the office_mask layer in the Timeline panel, and press the F key to display the Mask Feather property for the mask.
- Increase the Mask Feather amount to 1.5, 1.5 pixels.
- Hide the properties for the office_mask layer, and then choose File > Save to save your work.
