Opacity effects Opacity is a basic transparency effect that can be applied to any object. When an object’s 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. Transparency palette options Options for opacity, transfer mode, scope, and masks appear in the Transparency palette. When an object is selected, the Transparency pal- ette displays the object’s opac- ity and transfer mode. Opacity. Drag the slider or enter a percentage to set the opacity of a selected object.
