Once you have the semiotic toolkit in place, you can start applying it to the specific languages of different media forms. This is where the terminology of codes and conventions becomes essential. In this lesson you will learn the standard categories of codes — technical, symbolic and written — and you will develop a working vocabulary for analysing mise-en-scène, camera, editing, sound and written/graphic design across different media forms.
The two terms are often used interchangeably, but they are slightly different and the distinction matters.
Codes are general; conventions are particular. Saying "the mise-en-scène code" describes a category; saying "the horror convention of dim, low-angle lighting" describes a specific patterned use.
| Concept | Definition | Example |
|---|---|---|
| Code | Signifying system with rules | Camera, editing, sound |
| Convention | Established pattern within a form | Over-the-shoulder shot in dialogue |
| Genre Convention | Pattern specific to a genre | Jump scare in horror |
| House Style | Conventions specific to a brand or publication | Tabloid red masthead |
Technical codes are the codes of the production apparatus — camera, editing, sound and lighting. They are the building blocks of moving-image media. Although we will go deeper into each in later lessons, here is an overview.
The camera has three main variables: shot size, angle and movement.
Shot sizes run from extreme long shot to extreme close-up, each with different connotations:
| Shot | Connotation |
|---|---|
| Extreme Long Shot | Character dwarfed by environment; isolation or scale |
| Long Shot | Context established; full figure in environment |
| Medium Shot | Conversational; relational |
| Close-Up | Emotional intensity; intimacy |
| Extreme Close-Up | Heightened emotion; key detail |
Angles carry strong ideological connotations. A low-angle shot conventionally elevates a character, making them seem powerful; a high-angle shot diminishes them. A Dutch angle (tilted frame) signals disorientation or unease. An eye-level shot connotes parity between viewer and subject.
Movement — pans, tilts, tracking shots, crane shots, handheld — all carry meaning. A slow push-in intensifies focus; a handheld shake connotes immediacy or chaos.
Editing is the arrangement of shots in time. The dominant editing convention in mainstream cinema is continuity editing, which uses techniques such as the 180-degree rule, match-on-action and eyeline match to produce an illusion of seamless spatial and temporal flow. When continuity is broken — by jump cuts, flash-forwards, or unconventional transitions — the effect is to defamiliarise and draw attention to the constructedness of the text.
Pace is as important as technique. A scene with many short shots feels urgent; a scene with fewer, longer takes feels contemplative.
Sound codes include dialogue, sound effects, music and silence. A critical distinction is between diegetic sound (sound belonging to the world of the story — a character's voice, a door slamming) and non-diegetic sound (sound added for the audience — soundtrack music, voice-over narration).
Lighting is often grouped with mise-en-scène but is really a technical code in its own right. High-key lighting (bright, low-contrast, few shadows) connotes comedy, romance and safety; low-key lighting (dim, high-contrast, deep shadows) connotes tension, thriller, horror. The placement of the key light, fill light and back light — the classic three-point setup — shapes how we read character.

Symbolic codes are codes of mise-en-scène and iconography — the meanings carried by objects, settings, costumes, colours and composition. They are called symbolic because their meanings are largely conventional and culturally learned rather than tied to the technical apparatus.
Mise-en-scène literally means "putting in the scene" and refers to everything visible in the frame that is not a product of camera or editing: setting, costume, props, performance and lighting (though lighting straddles categories). In the next lesson we will analyse mise-en-scène in depth; here we note that it is the principal field of symbolic meaning in visual media.
Iconography refers to the characteristic visual elements associated with a particular genre or form. Westerns have an iconography of six-shooters, Stetsons, horses, dusty streets and saloon bars. Sci-fi has an iconography of spacecraft, control panels, space suits and alien landscapes. News has an iconography of desks, maps, microphones and studio backdrops. Iconography is a powerful short-hand: a single iconographic element can place a whole text within a genre.
Colour is a symbolic code in its own right, though its meanings are culturally specific. In Western media, red commonly connotes passion, danger or romance; white often connotes purity or sterility; black often connotes sophistication or menace. But colour codes are not universal — in some cultures white is a mourning colour. Good analysis acknowledges cultural specificity rather than treating colour associations as natural.
Written and graphic codes are vital in print and digital media. They include typography, layout, colour, image/text relationships and interactive elements.
Typeface choice is one of the most consequential choices in print design. Broadly:
