Opacity effects
Opacity is a basic transparency effect that can be applied to any
object.
When an objects opacity is less than 100%, the object appears partly
transparent. You can reduce the opacity of a text object, for example,
so a background image is visible through the type.
You use the Opacity slider to set the opacity of objects. The Opacity
slider is available in the toolbox and in the Transparency palette. The
slider in the toolbox will set opacity for one or more selected objects.
The slider in the Transparency palette is available only when a single
object is selected.
Opacity affects the overall transparency of an object, so the Opacity
slider is a master control for all transparency effects applied to an
object.
For example, you can use a channel mask to make an oval vignette
from a photograph. At the edge of the oval, the photograph becomes
completely transparent. If you then reduce the opacity, the visible
part of the image becomes partly transparent.
