In this photoshop tutorial we will cover the bevel and emboss tools within the layer styles dialog. If you have not learned about layer styles, please refer to the previous tutorial.
The bevel effects make an object look as though it has been chiseled away, and is great for giving hard, sharp edges. The emboss options are a bit softer and make objects seem to rise out of the document or look as though they have been stamped into the page. In addition to deciding on a bevel or emboss, you also have control over the size of the effect, the direction of light and shadows and the shape of the edges. The option to apply a texture is also worth investigating and opens up even more options.
