Add
a drop shadow to give depth to text in an image.
In the Layers palette, select the layer containing
the text to which you want to add a drop shadow.
Click the Layer Style button at
the bottom of the Layers palette and choose Drop Shadow from the
list that appears.
If possible, position the Layer Style dialog box so that
you can see the layer and its drop shadow.
Adjust the settings to your liking. You can change various
aspects of the shadow, including the way it blends with the layers
below it, its opacity (how much the underlying layers show through),
the angle of the light, and its distance from the text or object.
When you’re satisfied with the drop shadow, click OK.
To use the same drop shadow settings
on another layer, drag the Drop Shadow layer in the Layers palette
to the other layer. When you release the mouse button, Photoshop
applies the drop shadow attributes to the layer.
