Layer Styles are nothing new. They’ve been used and abused again and again. Despite their ubiquity, or perhaps because of it, many designers do not yet realize the full potential of this handy menu. Its beauty lies in our ability to create an effect and then copy, modify, export, hide or trash it, without degrading the content of the layer.
To redefine your design, layering can be your best friend. With different styles, it can be hard to choose which one, you want to use. So these techniques can give you a bump effect or the ever rising 3-D modeling.
