Sketching

Hatching is the method used to play with the brightness of an image. It is the sketching of closely spaced parallel lines. This is done by varying the thickness, spacing and number of lines. A number of thick closely spaced lines produce a darker image. When lines are placed at an angle to each other, it is called cross-hatching . This method is used to create contrast. Different colors may be indicated by using different line-work.

The technique of stippling involves using small dots, to indicate shading and solidity. The denser the dots, the darker the shade.
