Body parts.
Body parts, in relation to the modeling industry, means making available body parts of a model, such as hands, legs, fingers, hair, teeth, etc., to create photographs or promotional videos. It is often the case that “body part models” are booked in addition to a booked “hero model” (leading actor in an advertising campaign) in order to fill out certain sections in an advertising production. It's about close-ups where the corresponding body part can be seen. Sometimes an attempt is made to find a hero model during the casting process, which also meets the requirements in the body part area.
