Specify opacity for a layer or group

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

Note: You cannot change the opacity of a background layer or a locked layer. You can, however, convert a background layer into a regular layer, which does support transparency. See Convert background and layers.
  1. Select a layer or group in the Layers palette.
  2. Do one of the following:

    • In the Layers palette, enter a value in the Opacity text box or drag the Opacity pop‑up slider.

    • Choose Layer > Layer Style > Blending Options. Enter a value in the Opacity text box or drag the Opacity pop‑up slider.

    • Select the Move tool and type a number indicating the percentage of opacity.

    Note: To view blending options for a text layer, choose Layer > Layer Style > Blending Options, or choose Blending Options from the Add A Layer Style button at the bottom of the Layers palette menu.
