A Prompt Vocabulary: Photographic Terms Models Understand

Generative models learned from images paired with text, much of it professional photographer captions, stock metadata and catalogue descriptions. So the language of photography is native to them, while everyday phrasing is an approximate translation.

Shot size and framing

• Close-up — the face fills most of the frame.
• Medium close-up — head and shoulders, the classic portrait.
• Waist-up — the most versatile portrait framing.
• Full-length — the whole figure.
• Wide shot — a person in an environment that matters.
• Detail shot — a fragment: hands, eyes, an object.

Angle and camera position

• Eye level — neutral and safest.
• Low angle — the figure reads larger and more imposing.
• High angle — the figure reads smaller, the face larger relative to the body.
• Three-quarter view — between frontal and profile.
• From behind, over the shoulder — narrative angles.

Light

The most important section: models reproduce light confidently when it is named correctly.

• Soft diffused light — gradual shadows, even tone.
• Hard light — crisp shadows with defined edges.
• Window light — soft from one side, a natural gradient.
• Backlight, rim light — source behind the subject, glowing contour.
• Fill light — illumination of the shadow side.
• Golden hour — low warm sun.
• Blue hour — twilight after sunset, cool palette.
• Overcast — even light without shadows.
• Single-source studio lighting.

Optics and depth of field

• Portrait lens, an 85mm look — flattering facial proportions, compressed perspective.
• Wide-angle — more environment, pronounced perspective, edge distortion.
• Telephoto — heavily compressed perspective, subject separated from background.
• Shallow depth of field — blurred background.
• Deep focus — everything sharp.
• Bokeh — the character of out-of-focus highlights.
• Vignetting — darkened corners, adds credibility.

Materials and textures

A separate group with a large effect on realism.

• Visible skin texture, natural pores.
• Matte fabric, glossy surface, rough concrete, polished wood.
• Film grain — adds photographic character.
• Reflections, specular highlights, translucency.

Mood and processing

Less rigorous terms here, but effective ones.

• Muted palette, saturated colours.
• Warm tone, cool tone.
• High key — a bright range without deep shadows.
• Low key — a dark range with a single source.
• High contrast, low contrast.

What the vocabulary does not solve

Terminology makes a request more precise but does not repeal the main rule: there must not be too many elements. Twenty professional terms perform worse than six — competition for influence does not go away.

And one more thing: a term should serve the intent rather than decorate the request. "Low key" inside a description of a bright morning frame creates a contradiction the model will resolve unpredictably.

A practical template

Subject and action → shot size → setting → light → optics → one texture detail. Six elements, one from each section. Such a request is followed more accurately than any long enumeration.
