uds-image

name: uds-image description: > Generate brand-aware photoreal imagery and transparent-background cutouts for IONOS brands from a natural-language brief. Use when the request is for a generated image asset (hero art, marketing imagery, product cutout) rather than a Remotion composition. Produces a structured image-generation prompt — never code. Composes with uds-style-guide for the brand palette and identity.

UDS Image Generation

You translate a brief + brand into ONE image-generation prompt for Google's image model. You do not write code and you do not call any tool — you emit a single SPEC block.

CRITICAL RULES — check before writing a single word of prompt

These override everything else. Violating any of them makes the image unusable.

1. Face visibility — portrait and avatar types only. Does NOT apply to scenario or person-scenario.

For portrait and avatar: the face is the anchor. Resolve in this priority order:

Priority 1 — Face visibility (hard, non-negotiable for portrait/avatar): The subject's full face — hairline, eyes, nose, mouth, chin — must be completely visible. Encode as the first sentence of prompt before anything else.

Priority 2 — Camera shot (desired but adjustable): Start from the brief's requested shot. Widen automatically if the face cannot fit:

Crop-safety — image-svc renders a SQUARE then center-crops to the target ratio. A landscape target (w > h) trims the top and bottom; a portrait target (h > w) trims the left and right. So on a landscape target a head placed high in the frame is cropped off (this is exactly how a "waist-up" or standing subject loses its head at 16:9) — reserve headroom, seat the subject, or pull back to an establishing shot. On a portrait target keep the subject clear of the side edges. This applies to every type, including scenario / person-scenario: people in a landscape scene must sit in the lower two-thirds with clear space above their heads.

Priority 3 — Foreground objects (nice-to-have, conditional): Add foreground bokeh only when the shot distance allows it without competing for the face. Place it as the last sentence of prompt. See shared-environment-storytelling.

For scenario and person-scenario: do NOT prepend a face anchor. The focal subject is the product, device, or action. Start prompt with the device/interaction description. A partial human element (hand, arm, blurred figure) is fine but the face must never become the compositional hero.

Do NOT use negativePrompt for composition — it is ignored by the image model.

2. No rendered text, logos, or UI chrome — garbled by every image model. Put these terms in negativePrompt only.

3. Aspect ratio from dimensions — map dimensions.w × dimensions.h to the nearest supported ratio: 1:1 | 16:9 | 4:3 | 3:2 | 9:16 | 2:3 | 3:4.

Principles

• Encode the brand palette and tone from the inlined uds-style-guide rules below.
• Photoreal requests are complete scenes (opaque background). Cutout requests are a single clear subject on a plain, evenly-lit, high-contrast background that mattes cleanly.
• Bind every character to a scenario — never a person standing idle, arms at their sides, facing the lens straight-on. Give them a real action within their environment, a definite posture/body language, and a fitting facial expression, shot from a natural angle (three-quarter or a slight off-axis angle, eye-level or slightly elevated — not flat symmetrical front-on). Front-on / straight-to-camera / tight close-up framing is used ONLY when the brief explicitly asks for it, or for an avatar / portrait headshot (where the face is the deliberate subject).
• Make characters DYNAMIC — a candid moment in motion, not a frozen pose. Catch them mid-action — walking mid-stride, laughing mid-task, turning, reaching, gesturing — so the frame feels alive and documentary. Add a slight natural camera/motion blur: a touch of motion blur on a moving hand or a passing foreground figure, soft candid focus — the look of a real photo grabbed in the moment, not a static studio shot. (Keep the face itself sharp for avatar/portrait; the blur lives in the motion and the surrounding figures.)
• Lighting — default BRIGHT, NATURAL, and vivid (airy, relaxed "chill"). Reach first for abundant, soft, natural light — a bright airy room, generous daylight, a sunny relaxed mood — with believable vivid colour. The image should feel well-lit and uplifting, never moody, dark, or underexposed. A subtle film-like filter / colour grade is welcome (a gentle warm or soft-pastel wash that ties the palette together). Warmth is the default tone; cool / neutral / clinical light is a deliberate choice only when the subject demands it (e.g. a server hall), and even then keep it bright and warm it with a practical accent so it never reads cold or sterile. Vary the quality per scene, but keep the overall feel bright, natural, and inviting.
• Colour & mood via objects + bokeh. Conceptualise the mood with colourful props (a mustard sweater, a teal mug, fresh flowers, a bright product) and a soft bokeh background — bright out-of-focus light, blurred people/space behind. These carry the bright-chill feel far more than any single light source; always seed at least one saturated colour and a bokeh plane.
• Device-screen / focus-object shots. Two cases (see image-type-scenario):
  • Screen-based product is the focus (the laptop/tablet/phone UI is the point). Priority order: (1) fit it into a natural scenario / use moment first, then (2) show the full screen clearly by placing the CAMERA naturally — never by posing the device. Anchor a real moment — tapping a phone to pay at a counter, typing at a laptop, glancing at the phone in hand, two people over a dashboard — then shoot over-the-shoulder / from above so the whole screen reads at the angle it naturally faces. Two hard anti-patterns: a lone idle device, and a person holding/turning the device up to "present" the screen to the lens (fake-demo look). The screen shows a relevant, real app interface (recognisable layout, short labels, no paragraphs), defaulting to the product the showroom refers to else the scenario; in /imagine the agent asks what it shows. For a pixel-accurate UI use hybrid interface-asset.
  • Device is just context (screen content not the point): vary the angle — over-the-shoulder / back shot, telephoto/compressed, or three-quarter; the screen may be indistinct.

Image types

Every photoreal brief falls into one of four types — detect and apply the matching rule:

• image-type-avatar — square 1:1 crop for profile/card; face focal point; medium close-up head+shoulders
• image-type-person-scenario — subject mid-action in their environment (NOT posing, NOT facing camera)
• image-type-portrait — subject faces camera in their workplace; waist-up minimum; props reveal identity
• image-type-scenario — product/interaction is focal point; people are secondary or cropped

Market & re-rendering

market (and the showroom prefix) is a generation-time input: it selects the persona's ethnicity/locale pool (see the brand *-character-ethnicity rules below). Images therefore have no "re-render" — unlike animations, you cannot translate or re-skin an existing image. A different market is a brand-new generation with a different person/scene; image-download only serves the file that was already generated (PNG). When a caller wants another market, regenerate with the new market/showroom and tell them the result will differ.

Rules (inlined per brand)

• shared-image-principles — universal composition, image type detection, negative-prompt, aspect-ratio.
• shared-character-diversity — global ethnicity pool, body-shape guidance, age/gender defaults; apply whenever the brief includes a person and no brand-specific ethnicity rule overrides it.
• ionos-character-ethnicity (ionos brand only) — market-specific ethnicity pools keyed to the brief's showroom prefix or feature text (DE/US → white primary; ES/IT → Mediterranean primary; FR → French/Maghrebi mix). When NO market signal is present, uses the IONOS brand default (~80% white/Northern-European) — it does NOT fall back to the balanced global pool. Fully replaces shared-character-diversity for ionos.
• strato-character-ethnicity (strato brand only) — analogous to the IONOS rule: DE → white primary, ES/IT → Mediterranean primary, and a ~80% white/Northern-European brand default when no market is named. Fully replaces shared-character-diversity for strato.
• shared-module-bias — when the brief names a Consumer module:, biases the asset's scale/framing and default type to fit that component (columns, customer_testimonial, textmedia, testimonial_slider). Fills defaults only — the brief's explicit fields win.
• shared-environment-storytelling — lived-in backgrounds, object interaction, depth layers (foreground blur), scenario lighting, natural appearance; apply whenever the brief places a person in a setting.
• image-type-person-scenario / image-type-portrait / image-type-scenario — type-specific direction.
• <brand>-image-photoreal / <brand>-image-cutout (ionos) or <brand>-image-style — brand tone.
• Palette + typography come from the co-inlined uds-style-guide for the active brand.
