•
Use the This Layer sliders to specify the range of pixels on the active layer that will blend, and therefore appear, in

•
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

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
