With the selection active, we can fill with white to reveal those areas on the drop shadow’s layer. When it’s active, a double-box appears around the thumbnail.) (The layer mask thumbnail appears to the right of a layer’s thumbnail in the Layers palette. Note, however, that the drop shadow’s layer mask is still the active layer in the Layers palette. That makes a selection of the layer’s content. To do that, we can Command-click (Mac) or Control-click (Windows) on the Layers palette thumbnail for the layer below. Next, we’ll reveal the drop shadow only where we want it to fall. In this case, the menu command Layer> Add Layer Mask> Hide All is appropriate, which adds a layer mask that’s completely filled with black. To edit the drop shadow, we’ll use a layer mask rather than simply erasing the unwanted areas of the drop shadow. This not only keeps the bevel as a “live” effect that can be updated, it simplifies the Layers palette and prevents any unwanted misalignment of elements. In a normal workflow, I would apply the drop shadow, use the Create Layers command, then apply the bevel as a layer effect to the original Layer 1. NOTE: For the purposes of this tutorial, I used the Create Layers command after applying a drop shadow and a bevel. This prevents accidental misalignment of the elements, which could lead to an unwanted (but rather interesting) mis-registration effect. Also observe that immediately after creating the layers, I linked them to the original Layer 1. In the Layers palette, note that the new layer “Layer 1’s Drop Shadow” was created below the original layer, while the shadows and highlights of the bevel were added above the original layer. If in fact the image’s appearance changes, you can use Edit> Undo to restore the layer style.) (You’ll generally be notified that some aspects of layer styles cannot be retained through the conversion. Using the menu command Image> Layer Style> Create Layers, we can convert the layer style elements in to actual pixel-bearing layers. We’ll need to convert the drop shadow layer effect into an actual layer and then mask (or erase) the areas of the shadow that should not be visible.Īs you can see in the layers palette, this artwork consists of three layers: The top object, with both a Drop Shadow and a Bevel and Emboss applied as a layer style a middle layer that contains the four “pillars ” and a Background layer with a “sky.” In this example, the shadow of the foreground object should fall on the “pillars” but not on the “sky” behind. You’ll need to convert the drop shadow layer effect to a layer of its own, then edit that layer. Perhaps the shadow should fall on the content of the layer immediately below, but not the layer below that. Sometimes a drop shadow needs to fall on only part of the layer or layers below.
