There are a few different ways that you can apply a layer style to multiple layers in Photoshop. One way is to select the layers that you want to apply the style to, and then click on the “Layer Style” icon in the bottom right corner of the Layers panel. This will bring up a menu of all the available layer styles, and you can simply click on the one that you want to apply.
Another way to apply a layer style to multiple layers is to select the layers, and then go to Layer > Layer Style > Apply Layer Style. This will bring up a dialog box where you can choose which style you want to apply, and whether you want to apply it to all selected layers, or just the topmost layer.
If you want even more control over how your layer styles are applied, you can use the Layer Styles panel. To open this panel, go to Window > Layer Styles.
Here you’ll see a list of all the available layer styles, as well as options for customizing them. You can also use this panel to save your own custom layer styles for future use.
To apply a layer style using the Layer Styles panel, simply drag it from the list onto the layer or layers that you want to apply it to. You can also select multiple layers and then click on the “Apply” button at the bottom of the panel.
No matter which method you use, applying layer styles is a quick and easy way to add some extra polish to your images. So experiment with different styles and see what looks best for your particular project!
