Chapter 1 Orientation 55
The default blend mode is Normal. An object with a Normal blend mode above
another object in the list merely sits over that image with its normal colors. When a
different blend mode is applied to the upper object, the color pixels in the top image
are blended with the lower image in a certain way. For example, if the upper image is
set to the Add blend mode, the red, green, and blue (RGB) values of the upper image
are added to the RGB values of the underlying image. The resulting image is usually
much brighter than the original. An image set to the Stencil Alpha blend mode creates
a stencil using the image’s alpha channel.
The Layers tab contains controls for adjusting the opacity and blend modes of layers
and objects. The Opacity and Blend Mode controls are not displayed by default.
Note: The Opacity and Blend Mode parameters (including animation controls) for an
object also appear in the Inspector > Properties tab, as well as the Dashboard.
To show the Opacity and Blend Mode controls:
1 In the Layers tab, click the Show Columns button (the “>” button that is adjacent to Lock).
2 Make one of the following choices from the pop-up menu:
• Choose Opacity to show the Opacity controls.
The Opacity parameter is added to the Layers tab.
• Choose Blend to show the Blend Mode button.
The Blend Mode button is added to the Layers tab.
