Exclude Channels From Blending - Adobe Photoshop CS6 User Manual

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.)
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 panel 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 panel menu.
3. 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.
Advanced blending options

Clipped Layers As Group option selected
Select Transparency Shapes Layers to restrict layer effects and knockouts to opaque areas of the layer. Deselecting this option, which is

Select Vector Mask Hides Effects to restrict layer effects to the area defined by the vector mask.

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.
1. 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 icon at the bottom of the Layers panel.
