Layer opacity and blending

In the Layers panel, select one or more layers or groups.

Change the Opacity and Fill values. (If you selected a group, only Opacity is available.)

Select a layer or group from the Layers panel.

• From the Layers panel, choose an option from the Blend Mode pop‑up menu.

• Choose Layer > Layer Style > Blending Options, and then choose an option from the Blend Mode pop‑up menu.

Double-click a layer thumbnail, choose Blending Options from the Layers panel menu, or choose Layer > Layer Style > Blending Options.

• Select Blend Interior Effects As Group to apply the blending mode of the layer to layer effects that modify opaque pixels, such as Inner Glow, Satin, Color Overlay, and Gradient Overlay.

• Select Blend Clipped Layers As Group to apply the blending mode of the base layer to all layers in the clipping mask. Deselecting this option, which is always selected by default, maintains the original blending mode and appearance of each layer in the group.

• Select Transparency Shapes Layers to restrict layer effects and knockouts to opaque areas of the layer. Deselecting this option, which is always selected by default, applies these effects throughout the layer.

• Select Layer Mask Hides Effects to restrict layer effects to the area defined by the layer mask.

• Select Vector Mask Hides Effects to restrict layer effects to the area defined by the vector mask.

Select OK.

• Double-click a layer thumbnail.

• Choose Layer > Layer Style > Blending Options.

• Choose Blending Options from the Add A Layer Style icon  at the bottom of the Layers panel.

From the Advanced Blending area of the Layer Style dialog box, deselect any channels you don't want to include when the layer is blended.

Double-click a layer thumbnail, choose Layer > Layer Style > Blending Options, or select Add A Layer Style > Blending Options from the Layers panel menu.

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.

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.
