Layer style settings

Each layer style has its own collection of properties in the Timeline panel.

Align With Layer Uses the bounding box of the layer to calculate the gradient fill.

Altitude For the Bevel And Emboss layer style, the elevation of the light source above the layer, in degrees.

Choke Shrinks the boundaries of the matte of an Inner Shadow or Inner Glow prior to blurring.

Distance The offset distance for a Shadow or Satin layer style

Highlight Mode, Shadow Mode Specifies the blending mode of a bevel or emboss highlight or shadow.

Jitter Varies the application of a gradient’s color and opacity.

Layer Knocks Out Drop Shadow Controls the drop shadow’s visibility in a semitransparent layer.

Reverse Flips the orientation of a gradient.

Scale Resizes the gradient.

Spread Expands the boundaries of the matte prior to blurring.

Use Global Light Set this to On to use the Global Light Angle and Global Light Altitude in the Blending Options

property group instead of the individual layer style’s Angle and Altitude settings. This is useful if you have multiple

layer styles applied to the same layer and want to animate the position of the light for all of them.

Working with blending options for layer styles

Each layer style has its own blending mode, which determines how it interacts with underlying layers. The under-

lying layer in this context may or may not include the layer to which the layer style is applied. For example, a drop

shadow does not blend with the layer to which it’s applied, because the shadow falls behind the layer; whereas an

inner shadow does blend with the layer to which it’s applied.

Layer styles can be categorized as interior layer styles or exterior layer styles. Interior layer styles affect the opaque

pixels of the layer to which they’re applied. These include Inner Glow, Inner Shadow, Color Overlay, Gradient

Overlay, Satin, and Bevel And Emboss. Exterior layer styles do not blend with the pixels of the layer to which they’re

applied, but only interact with the underlying layers. These include Outer Glow and Drop Shadow.

If Blend Interior Styles As Group is set to On, interior layer styles use the blending mode of the layer.

If you modify a layer’s Opacity property, the opacity of the layer’s contents and the opacity of the layer styles are all

affected. If, however, you modify the Fill Opacity property in the Blending Options property group, the opacity of

the layer styles is unaffected. For example, if a text layer has the Drop Shadow layer style applied, decreasing the Fill

Opacity to 0 makes the text disappear, but the drop shadow remains visible.

Use the Blend Ranges From Source option to use the advanced blending options set for the Photoshop file that

determine what blending operations to perform based on the color characteristics of the input layer.
