"Still Actor" is the term used as the name suggests, for an actor for the making of still images. The implication is that Still Actor relies upon more skill, when done well, than "just a model". Though there are wonderful models who are also actors, and therefore Still Actors by definition, Still Actors may favor non-moving, silent forms of acting for artistic reasons. Still Acting may have its own methods and meanings, requiring additional skills beyond striking a pose, and holding it. Still Acting is primarily used in conjunction with some form of optical image, such as photography. The intersection of portraiture and Still Acting might involve the interpretation of the person through single or serial still images, and various motives, themes, emotions, intentions and complex meanings can be developed by skilled Still Actors.
In commerce and advertising, Still Acting in photographs may attempt to convey meanings that motivate potential customers to favor a specific product, or service. Still Actors have been involved in certain street and gallery performances where the contrast between the normal movement of persons in a place stands out against the motionless Still Actor.
