Film language describes how directors create meaning from moving images through signs, codes, and conventions. Moving images can not only entertain but also influence viewers through propaganda. Signs and codes are the basic units of meaning in film, with denotation being the literal meaning and connotation suggesting deeper cultural meanings. Editing and camera techniques like shot types, angles, and movement also manipulate time and space to influence the audience. Lighting, sound, visual effects, narrative structures, and genre conventions further shape the perceived reality and meanings in film.
