Exclude channels from blending
You can restrict blending effects to a specified channel when you blend a layer or group. By default, all channels are
included. When using an RGB image, for example, you can choose to exclude the red channel from blending; in the
composite image, only the information in the green and blue channels is affected.

Do one of the following:
•
Double-click a layer thumbnail.
•
Choose Layer > Layer Style > Blending Options.
•
Choose Blending Options from the Add A Layer Style button at the bottom of the Layers palette.
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.

From the Advanced Blending area of the Layer Style dialog box, deselect any channels you do not want to include
when the layer is blended.
Group blend effects
By default, layers in a clipping mask are blended with the underlying layers using the blending mode of the
bottommost layer in the group. However, you can choose to have the blending mode of the bottommost layer apply
only to that layer, allowing you to preserve the original blending appearance of the clipped layers. (See “Mask layers
with clipping masks” on page 323.)
You can also apply the blending mode of a layer to layer effects that modify opaque pixels, such as Inner Glow or
Color Overlay, without changing layer effects that modify only transparent pixels, such as Outer Glow or Drop
Shadow.
1
Select the layer that you want to affect.
2
Double-click a layer thumbnail, choose Blending Options from the Layers palette menu, or 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 menu.

Specify the scope of blending options:
•
Select Blend Interior Effects As Group to apply the blending mode of the layer to layer effects that modify opaque
pixels, such as Inner Glow, Satin, Color Overlay, and Gradient Overlay.
•
Select Blend Clipped Layers As Group to apply the blending mode of the base layer to all layers in the clipping
mask. Deselecting this option, which is always selected by default, maintains the original blending mode and
appearance of each layer in the group.
