Prime lenses
Camera lenses with a fixed focal length, as opposed to zoom lenses. Prime lenses can add richer production values that reflect well on brands.
Principal Actor
An Actor with a speaking role on camera. This specific classification can mean different things depending on the type of production (commercials are different than movies and TV shows) or the contract an actor is working under.
Principal Photography
Is the phase of film production in which the bulk of the movie is filmed, with actors on set with the cameras filming, and is distinct from pre-production and post-production. Principal photography can be the most expensive part of film production, due to actor, director, and set crew salaries, as well as the costs of certain shots, props, and on-set special effects.
