A model is a person with a role either to display commercial products or to serve as an artist’s model.

Modelling entails using one’s body to represent someone else’s body or someone’s artistic imagination of a body. For example, a woman modelling for shoes uses her foot to model the potential customers’ feet. Modelling thus is different from posing for potrait.  Photography,potrait painting, and distinct from other types of public performance, such as acting or dancing. Personal opinions are normally not expressed, and a model’s reputation and image are considered critical.
