Part 7 - Bump Map

A bump map is used to create a more natural looking skin effect, producing bumps and creases in the skin in desires locations..

To create the bump map, the texture image was first 'De-saturated' to remove all colouring. This is followed by adding a 'High Pass' filter effect, which removes a majority of the shading on the image and highlights the creases and imperfections of the skin.

As you can see from the screenshots above, the bump map increases the realisticness of the skin and features.
