To 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.

In the Advanced Blending area of the Layer Style dialog box, deselect any channels you do not want to include
when the layer is blended.
Grouping 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 “To create a
clipping mask” on page 437.)
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.
