The verb 'porträtieren' (to portray) is derived from the noun 'das Porträt' (portrait). It means to represent a person through art or through a description.

A 'Porträt' (portrait) can be a picture (painting, photo) or a text or film. The context reveals the meaning: if it is about art and painting, a picture is meant. If it is about newspapers or television, a description is meant.

'das Bild' and 'das Porträt' can both be a visible representation, for example a photo or a painting. 'Bild' is very general and can show people, animals, things, or landscapes. 'Porträt' is more specific: it shows a person, often especially their face, and usually feels somewhat more artistic or intentional. The words can be confused when a person can be seen in a picture. If the person themselves is the focus, 'Porträt' fits better; otherwise, 'Bild' is often more natural.
