Using "Key Line" on the Olympus OM-D E-M1
WHAT IS KEYLINE PHOTOGRAPHY?
With the keyline technique the colours are reduced to only a few. In the image, several different shades of a colour are thus combined to fields of a single colour and bordered with a black "key line" (keyline) in the focus area.

In the blurred area the fields remain without black outlines.

This style is often used for comics. (Source: Olympus)
