In the Advanced Blending area of the Layer Style dialog box, choose an option from the Blend If pop-up menu. 
Choose Gray to specify a blending range for all channels. 
Select an individual color channel (for example, red, green, or blue in an RGB image) to specify blending in that 
channel. 
Use the This Layer and Underlying Layer sliders to set the brightness range of the blended pixels—measured on a 
scale from 0 (black) to 255 (white). Drag the white slider to set the high value of the range. Drag the black slider to 
set the low value of the range. 
To define a range of partially blended pixels, hold down Alt (Windows) or Option (Mac OS), and drag one half of a 
slider triangle. The two values that appear above the divided slider indicate the partial blending range. 
Keep the following guidelines in mind when specifying blending ranges: 
Use the This Layer sliders to specify the range of pixels on the active layer that will blend, and therefore appear, in 
the final image. For example, if you drag the white slider to 235, pixels with brightness values higher than 235 will 
remain unblended and will be excluded from the final image. 
Use the Underlying Layer sliders to specify the range of pixels in the underlying visible layers that will blend in the 
final image. Blended pixels are combined with pixels in the active layer to produce composite pixels, whereas 
unblended pixels show through overlying areas of the active layer. For example, if you drag the black slider to 19, 
pixels with brightness values lower than 19 will remain unblended and will show through the active layer in the 
final image. 
Layer effects and styles 
Layer effects and styles 
Photoshop and ImageReady provide a variety of effects—such as shadows, glows, bevels, overlays, and strokes—that 
let you quickly change the appearance of a layer’s contents. Layer effects are linked to the layer contents. When you 
move or edit the contents of the layer, the effects are modified correspondingly. For example, if you apply a drop 
shadow effect to a text layer, the shadow changes automatically as you edit the text. 
The effects that you apply to a layer become part of the layer’s custom style. When a layer has  a style, an “f  ”  icon  
appears to the right of the layer’s name in the Layers palette. You can expand the style in the Layers palette to view 
all the effects that compose the style and edit the effects to change the style. 
When you save a custom style, it becomes a preset style. Preset styles appear in the Styles palette and can be applied 
with a single click. Photoshop and ImageReady provide a variety of preset styles to fill a wide range of uses.
