ADOBE PHOTOSHOP 6.0 239 User Guide Editing a layer mask You edit a layer mask by adding to or subtracting from the masked region. To edit a layer mask: 1 Click the layer mask thumbnail in the Layers palette to make it active (the mask icon ( ) appears to the left of the layer thumbnail). 2 Select any of the editing or painting tools. Because the layer mask is a grayscale alpha channel, the foreground and background colors default to grayscale values when the mask is active. As you edit, the mask thumbnail displays the changes. 3 Do one of the following: • To subtract from the mask and reveal the layer, paint the mask with white. Background painted with black, head painted with white, neck painted with gray • To make the layer partially visible, paint the mask with gray. • To add to the mask and hide the layer or layer set, paint the mask with black. To edit the layer instead of the layer mask, select it by clicking its thumbnail in the Layers palette. The paintbrush icon ( ) appears to the left of the thumbnail to indicate that you are editing the layer. To paste a selection into a layer mask, Alt-click (Windows) or Option-click (Mac OS) the layer mask thumbnail in the Layers palette to select and display the mask channel. Choose Edit > Paste, drag the selection in the image to produce the desired masking effect, and choose Select > Deselect. Click the layer thumbnail in the Layers palette to deselect the mask channel. To edit a layer mask's options (Photoshop): 1 Double-click the layer mask's thumbnail in the Layers palette. 2 To choose a new mask color, click the color swatch in the Layer Mask Display Options dialog box, and choose a new color. For more information, see "Using the Adobe Color Picker" in online Help. 3 To change the opacity, enter a value between 0% and 100%.
