Lighting

Light as language: key, fill and shadow, the moral vocabulary one textbook gives them and the grey scale another reduces them to.

Lighting is the quality, direction, source and colour of the light in a shot: high-key evenness or low-key shadow, hard or soft, motivated by a lamp in the frame or added from nowhere. It decides what can be seen and what the seeing feels like, and the second job is the one worth teaching. Students read shadow as "mood" and stop. Shadow is first a decision about who is allowed to be seen clearly and who is not, and a film makes that decision face by face, often inside a single room. The question is not "is it dark" but "who is lit, by what, and does the source have to be believed".

A moral vocabulary or a grey scale

Giannetti gives light an ethics. "What's photographed in bright light is there for the world to see. But what's photographed in darkness is furtive, scary." He sorts keys by genre: comedies and musicals in high key, tragedies in high contrast, and "mysteries, thrillers, and gangster films are generally in low key, with diffused shadows and atmospheric pools of light". He knows the vocabulary can be reversed, and his best example is an assault in broad daylight: "we tend to associate light with safety, high-key lighting is generally nonthreatening and reassuring. But not always."

Bruce Block strips the ethics out. Light is tone, tone is brightness, and brightness works by contrast and affinity. "Without tonal contrast, lines don't exist." A shadow is not furtive; it is an edge, and the edge is what lets the eye find a shape. Bordwell and Thompson sit between them: "the power of a shot is centrally controlled by light quality, direction, source, and color", and they quote Sternberg's "drama and adventure of light" as the most important component of mise en scène. Their contribution is the default against which everything else is measured, the classical three-point set-up of "key light, fill light, and backlight".

Boggs records the reaction against that default. "Today's filmmakers generally strive for a very natural effect in their lighting", and he lets Vilmos Zsigmond say why: "I like to have windows in my shots—windows, or candles or lamps. Those are my true light sources." The disagreement is about where meaning lives. Giannetti puts it in the shadow itself, Block in the contrast, Film Art in the convention, and the naturalists in the plausibility of the source. Zsigmond's summary covers all four: a cinematographer "improves on nature".

On the bench

Psycho — the parlour scene runs two lighting schemes in one room. Marion sits in soft, rounded compositions near a lamp; Norman sits low and angular in hard shadow, under an owl with its wings spread (Norman among the birds). This is Giannetti's vocabulary applied face by face, and it is doing narration the script withholds: sympathy consolidates around Norman while the light has already sorted him with the predators.

Alice — the prologue is the opposite programme. A painted sky drenched in sunset red, fog, a soundstage, a set that declares itself a set. The light is a quotation of a studio-era technology for painting emotion onto weather, and it makes no claim to a plausible source. Zsigmond's windows and candles are exactly what it refuses. The film spent $85,000 on that refusal (The $85,000 backdrop). And Chapman pushed the night stock is the reminder that a lighting look can be made in the lab: Taxi Driver's smeared neon and unsettled blacks came from over-developing night-rated stock, a processing decision as much as a lighting one.

What to look for

Where is the key light, and is there a source in the frame that could account for it?
Who gets soft light and who gets hard, and does the film ever swap them?
What lives in the shadow the film maintains, and when is it finally lit?
Is the scene lit the way its genre expects, and if not, what is the reversal for?

In the books

Yet the power of a shot is centrally controlled by light quality, direction, source, and color.
