Displacement Modifier
The displacement modifier moves vertices along their normal according to a height map. To get nice results a lot of polygons are needed which is probably the biggest disadvantage of the displacement modifier.
On the images below you can see a simple example of displaced subdivision surfaces. This technique allows you to model a head with the subdivision surface tools and add details like wrinkles to the head with a displacement map.

- Texture: The path to the height map. A height map is a simple grey scale image where white is equivalent to maximum offset and black is equivalent to no offset.
