(See "Creating clipping groups" on page 319.) If you want to reveal the bottom layer in the group, make sure the Blend Clipped Layers as Group option for the bottom layer is selected. (See "Grouping blend effects" on page 299.) 2 Select the top layer (the layer that will create the the knockout). 3 Do one of the following: • (Photoshop) Double-click a layer thumbnail, choose Layer > Layer Style > Blending Options, or choose Blending Options from the Layers palette menu. Note: To view blending options for a text layer, choose Layer > Layer Style > Blending Options, or choose Blending Options from the Layers palette menu. • (ImageReady) Choose Window > Layer Options/Style. In the Layer Options palette, if the advanced options are not showing, choose Show Options from the palette menu or click the Show Options button to view all of the options. 4 Choose an option from the Knockout pop-up menu: • Shallow to knock out to the first possible stopping point such as the bottom of the layer set or clipping group containing the knockout option. • Deep to knock out to the Background. If there is no Background, Deep knocks out to transparency. 5 Lower the fill opacity or change the blending mode to create the knockout effect. (See "Specifying fill opacity" on page 296 and "Choosing a blending mode" on page 296.) 6 Click OK. Restricting blending to channels (Photoshop) You can restrict blending effects to a specified channel when blending a layer or layer set. By default, all channels are included when blending a layer or layer set. The channel selections vary based on the type of image you are editing. For example, if you are editing a RGB image, the channel choices are R, G, and B. If you are editing a CMYK image, the channel choices are C, M, Y, and K. (See "About color channels" on page 93.) When using an RGB image, for example, you can choose to exclude the Red channel from blending; in the composite image, only information contained in the Green and Blue channels are affected. To exclude channels from blending: 1 Double-click a layer thumbnail, choose Layer > Layer Style > Blending Options, or choose Blending Options from the Layers palette menu. Note: To view blending options for a text layer, choose Layer > Layer Style > Blending Options, or choose Blending Options from the Layers palette menu. 2 In the Advanced Blending section of the Layer Style dialog box, deselect any channels you do not want to include when the layer is blended.
