Specifying opacity

A layer's opacity determines to what degree it obscures or reveals the layer beneath it. A layer with 1% opacity appears nearly transparent, while one with 100% opacity appears completely opaque.

To specify opacity for a layer:

1 Select the layer in the Layers palette.

2 In the Layers palette, enter a value for Opacity or drag the Opacity pop-up slider.
