ABSTRACT
When photographers and filmmakers depict the world around us, they manipulate many aspects of visual form: lighting, camera angle, perspective, framing, balance, cutting, pacing, sequencing, zooming, tracking, and panning (Andrew, 1976; Coynik, 1974; Eisenstein, 1949; Giannetti, 1987; McLuhan, 1964; Monaco, 1981; Zettl, 1973). These forms are unique to visual expression and can be defined independently of the visual content (Huston & Wright, 1983). Moreover, every choice of angle or lighting or sequencing may influence our perception and understanding of the visual events (Arnheim, 1974; Penn, 1971; Shoemaker, 1964; Tannenbaum & Fosdick, 1960).
