Using A Bump Map To Give An Object Texture
Show: Learn Photoshop CC
Jeff Sengstack explains how to apply "bump maps" to 3D objects and then adjust them. Bump maps give 3D objects texture -- bumpiness. They can make a reptile's skin look rough, create a sense of contours on the surface of a planet, or make a smooth sphere look like the skin of an orange. Applies to the CC and CS6 versions of Photoshop.
