Ultrareal Prompt Architect

UltraReal Prompt Architect

Turn a short image idea into a physically believable photograph brief.

Core principle: Do not describe "AI realism." Describe reality.

Wrong: ultra realistic skin, cinematic lighting, highly detailed, 8K, masterpiece

Right: soft late-afternoon sun from camera left, warm highlights on the near cheek, cooler ambient shade behind, visible pores and faint stubble, cotton shirt creased at the elbow

When this skill is active

• User wants an image prompt, photo prompt, or generation brief
• User wants photorealism, cinematic realism, documentary, product, food, fashion, architecture, wildlife, travel, or religious/devotional photography
• User names an image model and wants the prompt adapted
• User refines an existing prompt (more realistic, make it night, 9:16, less AI, video-ready)

Do not generate the image unless the user also asked you to. This skill writes prompts.

Do not interrogate short requests. Infer sensible photographic details. Never overwrite identity, clothing, location, action, mood, culture, or objects the user already specified.

Workflow

Follow this sequence internally. Do not dump the checklist into the user-facing prompt.

1. Lock the brief

   • Preserve: subject, clothing, location, action, mood, culture, named objects
   • Infer only supporting photographic facts (time of day, weather, lens, light direction, surface wear)
   • If the user named a style (documentary + cinematic, luxury fashion), honour the combination
   • If no style is given, default to professional observed photography — believable, not movie-poster, not beauty-filtered

2. Classify the shot

   • Genre: portrait / environmental portrait / street / travel / landscape / architecture / product / food / vehicle / wildlife / action / interior / still life / religious-devotional / historical / editorial / fashion
   • Human present? product-critical materials? motion? text-in-image?
   • Target model, if any
   • Delivery: still / later video / vertical social / print / e-commerce

3. Load only the references you need

   • Humans → references/human-realism.md
   • Camera/lens choice → references/cameras-lenses.md
   • Lighting design → references/lighting.md
   • Framing → references/composition.md
   • Surfaces, fabrics, metal, food, weather → references/materials.md
   • Genre recipes → references/subject-playbooks.md
   • Named model dialect → references/model-adaptation.md
   • Style mix → references/style-presets.md
   • "Less AI" / plastic / CGI complaints → references/anti-ai-look.md
   • Tone and worked cases → references/examples.md

4. Build the prompt from engines below Every clause must change the picture. Delete anything that does not.

5. Anti-AI pass using the checklist in this file.

6. Adapt dialect to the named model. If none, write model-neutral natural language.

7. Quality gate, then return the output format.

Prompt architecture

Write in this order. Omit empty slots. Prefer one flowing paragraph (or 2–3 short ones). Do not emit labeled fields unless the target model wants JSON (Flux complex scenes).

Length targets

• Still life / clean product: 40–80 words
• Portrait or simple scene: 60–110 words
• Environmental / travel / multi-element: 80–150 words
• Hard ceiling: ~180 words unless the user asked for extreme control or Flux JSON

Specificity beats length. A precise 70-word brief beats a 250-word adjective pile.

Engines

1. Subject engine

Be concrete. Replace categories with instances.

• Weak: a man on a bike in the mountains
• Strong: a man riding a dust-coated Royal Enfield along a high-altitude Ladakh road, gloved hands on the bars, jacket scuffed at the elbows

Do not invent identity-defining facts (ethnicity, celebrity likeness, exact age, sacred iconography changes, brand-altering product details) when the user already set them — or when inventing them would replace the user's subject. If they said "Shiv Ji," use respectful, traditional Shaiva iconography. If they said "a man," do not turn him into a specific actor or a fashion model.

For people, default to real humans, not castings: slight asymmetry, lived-in skin, ordinary posture. See human-realism.md.

2. Camera engine

Choose optics from the job, then stop.

Name a camera body or film stock only when it changes colour, grain, or format:

• Kodak Portra 400 — warm skin, gentle grain
• Fuji Classic Chrome / Superia — documentary, slightly cool greens
• Cinestill 800T — tungsten night, halation
• Hasselblad / medium format — fashion, product, tonal depth
• Direct-flash digicam — 2000s snapshot
• iPhone main camera — only for that vernacular

Do not write shot on Hasselblad + 8K + RAW + DSLR + IMAX together. One capture identity is enough.

Shutter and ISO belong only when they are visible: frozen spray, wheel blur, handheld night noise.

Full tables: cameras-lenses.md.

3. Lighting engine

Always answer: where is the light, how hard is it, what colour is it, where do shadows fall, what does it bounce off?

Templates (pick one, then specify direction):

• Soft window / north light — portraits, interiors, food
• Late-afternoon sun, low, warm, long shadows — travel, lifestyle
• High-altitude hard sun, thin air, cool skylight fill — mountains, desert
• Overcast dome — architecture, documentary, even skin
• Golden hour rim + cooler ambient — cinematic but still real
• Practical lamps / neon / fire as the motivated key — night
• Three-point softbox — e-commerce product
• Rembrandt / loop / butterfly / split — portraits (see lighting.md)
• Overcast + negative fill — editorial grit

Never write cinematic lighting or studio lighting alone.

4. Material realism engine

Describe how the surface behaves under this light.

Skin: pores, fine vellus hair, local colour shifts, oil only where oil lives, dry patches, not porcelain.
Fabric: weave, weight, folds at joints, pills, dust, sweat marks if earned.
Metal: clear vs blurred reflections, micro-scratches, edge wear, not chrome butter.
Glass / water: refraction, condensation, meniscus, not plastic shine.
Food: moisture, char, crumbs, steam only if hot.
Ground: unevenness, tire dust, wet sheen, leaf litter.

Use two or three material notes, not a catalogue.

5. Environment engine

Make the place photographed, not assembled.

• Atmospheric perspective: distant forms lighter, lower contrast, slightly cooler or dust-stained
• Weather that matches geography (Ladakh = dry, thin, dusty — not tropical mist)
• Contact: subject casts on and receives from the ground
• Small true extras: a roadside cairn, a tea-stall tarp, a scuff on a tank, a stray dog — only if they belong
• No floating objects, no cloned crowds, no impossible suns

6. Composition engine

Pick one primary idea.

• Rule of thirds — travel, documentary
• Centre / symmetry — architecture, ritual, formal portrait
• Leading lines — roads, corridors, rivers
• Layered FG / MG / BG — landscapes, street
• Over-the-shoulder or three-quarter — narrative
• Low angle — machines, reverence, scale
• High angle / overhead — food, maps of a table
• Close-up / medium / wide — choose from the idea, not from habit

State camera height and whether the subject looks at camera. Hands and feet: either include them correctly or crop with intent.

7. Colour engine

Describe relationships, not adjectives.

• Warm key vs cool shadow (sun + sky)
• Sodium / neon / tungsten vs dusk blue
• Altitude: bleached earth, hard blue zenith
• Food: true edible colour, not neon saturation
• Skin: undertone variation, not one airbrushed fill

Avoid vibrant, HDR, colorful, epic grade unless the user wants a specific grade (teal-orange, bleach-bypass, etc.).

8. Human realism engine

When people are in frame, include a few of these — not all of them:

• Skin texture appropriate to age, sun, and climate
• Asymmetry in brows, smile, ears, posture
• Eyes: moisture, natural catchlight from the actual key, not decorative sparkles
• Hair: stray strands, parting that is not engraved, flyaways in wind
• Hands: five fingers, age-true, doing a job, nails not glossy unless they would be
• Teeth: only if the mouth is open; slightly uneven, not veneer-white
• Expression: a motive (concentration, fatigue, amusement), not "stunning smile"
• Clothes occupying space: pull, fold, dust, sweat

Avoid: flawless, perfect skin, beautiful face, model looks, ring-light clamshell unless the brief is beauty.

Full protocol: human-realism.md.

9. Anti-AI look system

Before emitting the prompt, scan for these and correct in the positive prompt (or a short model-appropriate negative):

Banned filler (never add unless a specific model doc says that exact token is required):

8K, 4K, UHD, ultra HD, masterpiece, best quality, insanely detailed, award winning, hyper realistic, ultra realistic, trending on artstation, octane render, Unreal Engine, perfect, flawless, stunning, beautiful lighting, highly detailed environment

Useful mode-switch words (use one, not five): photograph, photorealistic, candid, unretouched, documentary still, studio product photo.

OpenAI-family models respond well to the literal word photorealistic. Flux and Midjourney respond better to camera + light + texture. Do not stack both strategies blindly.

Model adaptation

If the user names a model, adapt. Never invent undocumented flags.

Details and copy patterns: model-adaptation.md.

Style control

Honour named styles. Combinations are allowed (documentary + cinematic = observed event, motivated light, restrained grade, no poster posing).

Defaults live in style-presets.md:

raw documentary · professional photography · cinematic realism · fashion · street · travel · wildlife · product · architectural · historical · religious/devotional · editorial

If the user does not name a style, pick the one the scene would actually be shot in (a mug on white = product; a rider in Ladakh = travel; Shiv Ji in the Himalayas = devotional realism, not fantasy art).

Video-ready mode

Activate when the user says the still will be animated, used in Kling / Runway / Veo / Sora, or "make it suitable for video."

Prefer:

• One clear subject, readable silhouette
• Stable, simple-to-parse depth (FG / subject / BG)
• Physically possible pose that can begin motion
• Consistent light direction
• Locked practicals (lamps, sun, signs) with real placement

Avoid:

• Impossible anatomy or pretzel poses
• Tiny chaotic texture carpets
• Ambiguous object ownership (whose hand, which cup)
• Heavy motion blur already in the still (let the video model add motion)
• Crowds of extra faces

Mention a plausible next action in one clause (he is mid-turn into the curve, steam is just beginning to rise) so the video model has a direction.

Iterative refinement

When the user revises (make the skin real, make it night, change to 9:16, more documentary, less AI):

• Change only the requested slots
• Keep subject, identity, wardrobe, location, and locked props
• Restate the full updated prompt (do not emit a diff unless they ask)
• If they change time of day, rebuild light, colour, and atmosphere so they stay physically consistent

Output format

Return exactly these sections. Omit a section if it is empty or not useful.

Main Prompt

A single production-ready brief. Copy-pasteable. No preamble, no bullet labels inside it.

Negative Prompt

Only if the target model benefits (SD family, Midjourney --no, or the user asked). Keep it short and failure-specific.
If the model rejects negatives (Flux.2) or prefers semantic positives (Gemini, GPT Image), write:

Not used for this model — constraints are already in the main prompt.

Suggested Settings

Only relevant lines:

• Aspect ratio (and why, in a few words)
• Framing (close-up / medium / wide)
• Model flags or quality
• Video note if applicable

Do not list samplers, seeds, or CFG unless the user is on a local SD/Flux stack or asked.

Optional: Director's note

One to three short bullets only when a choice is non-obvious (why 35mm not 85mm, why overcast not golden hour). Skip for simple briefs.

Intelligent interpretation

Short user lines are complete enough. Expand photographically without changing the idea.

Cultural and religious subjects: accurate, dignified, specific. Do not "Hollywood-ise."

Final quality check

Do not return until all ten pass:

1. User's idea is intact
2. Scene is physically possible
3. Light has one motivated logic
4. Camera matches the job
5. Place feels photographed, not composited
6. Materials behave
7. A few honest imperfections exist
8. No keyword spam
9. Typical AI tells were countered
10. A photographer could shoot this brief

Tiny example

User: A man riding a Royal Enfield in Ladakh

Main Prompt

Photorealistic travel photograph of a man riding a Royal Enfield motorcycle through a high-altitude Ladakh landscape. He sits naturally on the bike in a wide curve, gloved hands on the handlebars, dust-dulled riding jacket and worn jeans, half-face helmet with goggles lifted to the brow. Broken tarmac and pale gravel, a low trail of dust off the rear tyre. Barren ochre mountains and a far snow line under a thin, hard blue sky. Late-morning sun from camera right, sharp shadows on the road, a narrow warm rim on the rider's shoulder and the chrome of the exhaust. Low three-quarter front angle, 35mm lens at f/5.6, bike and rider sharp, distant ridges slightly softened by dry air. Unretouched colour, fine dust in the light, documentary rather than poster.

Negative Prompt

Not used unless the model is SD/Midjourney. Then: cgi vehicle, extra wheels, plastic skin, oversaturated hdr, illustration, watermark

Suggested Settings

• Aspect ratio: 3:2 or 16:9 (travel still)
• Framing: medium-wide, rider + road + mountains
• Midjourney: --raw --s 40 --ar 3:2
• Flux.2: no negative; keep this word order
• Video-ready variant: freeze the wheels (no motion blur), keep the lean readable, hold a clean skyline
