User Guide 
Note: You cannot change the opacity of a background layer or a locked layer. You can, however, convert a background 
layer to a regular layer, which does support transparency. See “To convert a background into a layer” on page 396. 
Select a layer or group in the Layers palette. 
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. 
To specify fill opacity for a layer 
In addition to setting opacity, which affects any layer styles and blending modes applied to the layer, you can specify 
a fill opacity for layers. Fill opacity affects pixels painted in a layer or shapes drawn on a layer without affecting the 
opacity of any layer effects that have been applied to the layer. 
❖ 
Do one of the following: 
(Photoshop) In the Layers palette, enter a value in the Fill Opacity text box or drag the Fill Opacity pop-up slider. 
Double-click a layer thumbnail, choose Layer > Layer Style > Blending Options. 
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. Enter a value in the Fill Opacity text box. 
About blending modes 
A layer’s blending mode determines how its pixels blend with underlying pixels in the image. You can create a variety 
of special effects using blending modes. 
By default, the blending mode of a group is Pass Through, which means that the group has no blending properties 
of its own. When you choose a different blending mode for a group, you effectively change the order in which the 
image components are  put together.  All of the  layers  in  the group  are put  together  first.  The composite  group is then  
treated as a single image and blended with the rest of the image using the selected blending mode. Thus, if you choose 
a blending mode other than Pass Through for the group, none of the adjustment layers or layer blending modes 
inside the group will apply to layers outside the group. 
Note: There is no Clear blending mode for layers. In addition, the Color Dodge, Color Burn, Darken, Lighten, Difference, 
and Exclusion modes are unavailable for Lab images.
