VFX Prompt Book: Building Cyberpunk City Stills

Illustrative / Launch edition. This is a written craft guide; there is nothing to download.

Neon city concept stills are a favourite exercise for generative artists, and for good reason. They combine hard technical problems, such as reflections, haze and mixed light sources, with a mood almost everyone can recognise. The difference between a muddy result and a striking one usually comes down to how clearly you describe what a cinematographer would control. This guide walks through a structure for doing exactly that.

Think like a cinematographer

A film still is the product of decisions: where the camera sits, what lens it wears, where the light comes from, what hangs in the air. A prompt that lists only a subject ("a futuristic city at night") leaves all of those decisions to chance. A prompt that states them gives the tool something to hold on to. Treat your description as a shot order, not a wish.

The six parts of a prompt

Most strong prompts for city stills cover six things, in roughly this order.

• Subject: what the viewer is looking at, such as a rain-slick market street or a rooftop garden above a canyon of towers.
• Lens: wide, normal or long, and how close the camera feels. A long lens compresses signs and crowds into dense layers.
• Light: the sources and their colour, such as magenta shopfront glow against cool blue street lamps.
• Atmosphere: rain, steam, haze or fog, which make beams of light visible.
• Palette: a small set of dominant colours so the image feels designed.
• Composition: where the eye should travel, including foreground, midground and background layers.

Why order matters

Putting the subject first anchors the scene. Lens and light follow because they shape everything else. Atmosphere and palette refine the mood, and composition finishes the frame. If your tool weighs early words more heavily, this order protects what matters most.

Example prompt templates

These are written in prose so you can adapt them. Swap in your own invented places and details.

• A narrow noodle alley after rain, shot on a long lens from street level, with warm orange lantern light against teal shadows, drifting steam, and a lone figure in a clear raincoat framed in the middle distance.
• A wide aerial view of a harbour district at dusk, soft haze between towers, pink and cyan signage reflected in the water, with a foreground crane silhouette leading the eye to a glowing ferry terminal.
• A rooftop garden above a neon canyon, normal lens at eye level, green plant light mixed with violet billboard glow, light drizzle, and a bench and umbrella placed on the lower third of the frame.
• An elevated rail platform at night, wide lens with slight distortion, white fluorescent strips against blue-black sky, fog rolling beneath the tracks, and symmetrical composition pulling toward a vanishing point.
• A crowded night market seen from a bridge, long lens compressing hanging signs, amber and red palette with one cold white stall as a focal point, and drifting smoke from food carts.
• A quiet side street at the edge of the city, low angle, a single flickering sign casting green light on wet pavement, deep shadows, and almost no people, for a lonely mood.
• A control-room window overlooking a district of towers, interior blue monitor glow against orange outside haze, with a half-seen reflection of the viewer in the glass.

Notice what these share. Each one states a lens, a light relationship and a point of attention. None relies on vague praise words like "epic" or "stunning", which tell a tool very little.

Iteration tips

Treat generation as a loop rather than a single throw. Change one variable per round. If the image feels flat, adjust the light and leave everything else. If it feels cluttered, simplify the composition. Keep notes on which phrases produced which effects, because your own vocabulary becomes your most valuable asset.

Use rough thumbnails first. Generate at low detail to test composition, then refine the best candidate. Once you have a strong still, paint over it, fix hands and signage by hand, and grade the colour so it feels like part of a coherent project. The best concept artists treat a generated image as a rough, never as a finished piece.

Labelling and respecting artists

Two habits keep this craft healthy. First, label generated work clearly when you share it. A short note such as "concept still made with generative tools, then painted over" tells your audience what they are looking at and builds trust.

Second, respect other artists. Do not write "in the style of" followed by the name of a living artist. Describe the qualities you want instead: flat colour fields, heavy outlines, soft grain, high contrast. That approach is more useful to the tool and fairer to working illustrators, whose personal style is their livelihood. If a reference matters to you, study it, learn from it, and then make something that is yours.

A prompt is a brief, and a brief is only as good as its decisions. — Mara Venn, fictional concept designer

A short checklist before you generate

• Have I named the subject, lens, light, atmosphere, palette and composition?
• Is there one clear focal point?
• Am I describing qualities, not a living artist's name?
• Will I label the result honestly?

Cyberpunk cities reward patience. Learn to describe light the way a gaffer would, and your stills will start to look like frames from films that do not exist yet.
