Most AI UGC photos fail in the same way: the person is polished, centered, evenly lit, and emotionally blank. The output may be attractive, but it reads as stock photography rather than a moment somebody captured on a phone.

We generated more than 28 candidates with Nano Banana 2 in Masonry, rewrote the prompt set three times, and kept 13 outputs for this guide. The retained images show what the framework can produce; they do not prove that every generation will look real or that viewers cannot detect synthetic media.

The useful lesson was not “add more detail.” It was to give each detail a job: capture geometry, body position, surface texture, environmental evidence, or light direction.

This guide gives you the five-layer prompt, 13 prompt-and-output pairs, a current Masonry CLI recipe, and a rejection checklist. The city-inspired scenarios are fictional creative briefs, not representations of a nationality or evidence about how people from a place look or dress.

The quick answer

Build the prompt in this order:

  1. Capture: device, lens behavior, camera height, and framing.
  2. Action: a believable body position or mid-gesture moment.
  3. Subject: only the stable appearance, skin, hair, and wardrobe details the shot needs.
  4. Scene: three or four props that explain where the person is and what just happened.
  5. Light: direction, color temperature, and shadow behavior.

Generate four candidates, then reject rather than rationalize failures. Keep the one with coherent hands, eyes, reflections, product details, and capture geometry. When you need a recurring fictional creator, provide two clean reference views and keep the identity description stable.

Selling a real product? Do not start with a fictional creator prompt and hope the SKU survives. Use the real-product AI UGC workflow to anchor the keyframe to an approved product photo, review label and package fidelity, then carry that accepted frame into motion without inventing a testimonial.

Evidence boundary: the output images and prompts shown below are first-hand artifacts from this prompt set. The qualitative notes explain visible choices in those files. This is not a controlled model comparison or audience study, and it is not a conversion benchmark.

Why Most AI Portraits Look Fake (And How to Fix It)

A common model default is a smooth, evenly lit, centered face staring into the camera. The result can look more like a headshot or stock photo than a phone capture.

A candid-looking phone photo often has different evidence: an adult creator squinting into the sun, hair moving between frames, a phone propped against a coffee cup, or a camera angle that is slightly off center. The light has a plausible source and the scene contains evidence of what happened just before the frame.

You do not need every cue at once. You need enough observable specificity to move the model away from its polished default.

Across this prompt set, five layers made the retained outputs feel less staged:

  • Layer 1: Camera and angle — "iPhone front camera selfie from slightly above" or "shot from coffee table level looking across." This sets the entire visual framework.
  • Layer 2: Body in space — Not "sitting on a couch" but "lying sideways across a wide cream boucle sofa, head propped up on one hand, legs stretched out and slightly bent." The model needs spatial information.
  • Layer 3: Observable texture — Pores, freckles, fabric weave, flyaway hair, slight under-eye shadow, or humidity sheen. Choose two or three details that fit the brief; do not treat normal human features as defects.
  • Layer 4: Personal styling — Describe the wardrobe the fictional subject would choose for this particular scene. Do not use nationality as a shortcut for clothing, appearance, or personality.
  • Layer 5: Cinematic lighting — Light from two directions. "Warm amber floor lamp from camera-right, cool blue-pink neon from rainy window camera-left." This creates the depth and mood that flat lighting can't match.

Starting Simple: The iPhone Selfie Foundation

We started with one fictional adult in several indoor settings. The goal was to preserve the casual geometry of a front-camera photo while changing the scene.

Morning Bed Selfie

Candid UGC lifestyle iPhone front camera selfie photo of an adult woman in her early 20s with light tan skin, natural visible pores, subtle faint freckles across nose and cheeks, hazel eyes with warm green-brown tones, long brown hair slightly messy spread softly across white pillow with loose natural waves. She has a calm slightly sleepy expression with a soft relaxed smile, lips gently closed. Wearing a fitted white ribbed tank top with clean scoop neckline sitting just below the collarbone, thin fitted straps showing natural shoulder line. Subtle cotton-ribbed texture visible across chest. She is lying on slightly wrinkled white bedsheets with soft natural folds in the blanket, in a minimal bedroom with green indoor plants near a sunlit window in soft background. Natural morning sidelight, soft and warm, gentle glow along jawline and cheekbones, delicate soft shadows across the pillow and neck. Slightly top-down perspective looking down at subject lying on bed, close-up portrait, handheld with arm extended out of frame. Sharp focus on face with soft natural edge falloff. Cozy and intimate mood. No phone visible anywhere in frame. No filters. No artificial skin smoothing.

Why this works:

  • "Slightly top-down perspective looking down at subject lying on bed" gives the natural selfie angle you'd get holding a phone above yourself
  • "Slightly wrinkled white bedsheets with soft natural folds" — imperfect environments signal authenticity
  • "Sharp focus on face with soft natural edge falloff" mimics how phone cameras actually behave
  • The prompt describes fabric texture ("cotton-ribbed"), not just the garment — this prevents the model from generating flat, textureless clothing

Maintaining Facial Consistency Across a Feed

A single prompt can make a strong image. A campaign usually needs the same fictional adult across several scenes, and text alone does not reliably preserve that identity.

Use two clear reference views that you created or have permission to use: one front-facing and one three-quarter view. Keep the stable identity description short, then change the pose, wardrobe, setting, and light. Reference-guided generation reduces drift; it does not guarantee an identical face.

The current Nano Banana 2 Masonry contract accepts reference images through repeated --ref flags. The live contract documents 2–14 images for mixing, so this example uses two views rather than the older one-file recipe:

Prompt

masonry image "your prompt here" \ --model nanobanana-2 \ --aspect "4:5@2k" \ --ref creator-front.png \ --ref creator-three-quarter.png \ --output output.png

The two outputs below came from the same fictional creator direction in different scenes. The recognizable structure carries across, but details still move. Treat that as continuity to review, not identity lock.

Same Face, Different World

Same woman from reference photo taking an iPhone front camera selfie. She is sitting on wooden outdoor cafe chair wearing a white linen button-up shirt with sleeves rolled to elbows. Her brown wavy hair is loose and slightly wind-blown. She has a calm confident look with a slight smile looking directly into the camera. Warm golden hour sunlight, blurred outdoor cafe setting with greenery and string lights softly out of focus in background. Natural skin texture, warm sun glow on face. Effortless chic outdoor mood. No phone visible in frame. No filters. No skin smoothing.

Same woman from reference photo taking an iPhone front camera selfie. She is leaning against a sunlit brick wall on a city street wearing a camel-colored leather jacket over a simple white top. Her brown wavy hair is loose and flowing naturally. She has a cool relaxed expression with a slight smirk looking directly into the camera. Warm afternoon sunlight casting sharp shadows on the brick wall, blurred urban street with trees in background. Natural skin texture with warm sun glow. Urban street style mood. No phone visible in frame. No filters. No skin smoothing.

The key insight: references constrain the identity more effectively than repeating a long facial description. Only use a real person's likeness with permission, and never present a synthetic persona as a real customer or employee.

Ten City-Inspired Scenarios

The first two versions of this scenario set exposed different prompt failures.

We created ten fictional lifestyle briefs with different apartments, poses, wardrobes, and lighting setups. City names are art direction here, not identity labels. If a place matters to your campaign, replace imagined shorthand with a real location reference, brand research, or input from people who know it.

The Three Failures That Taught Us Everything

Version 1 was too editorial. We described full fashion-magazine makeup (razor-sharp contour, tightlined waterline, deep smoky eye) and runway outfits (structured bralette-style co-ord top, cold-shoulder blazer). The results looked like AI stock photos — technically impressive, emotionally dead.

Version 2 leaned on place stereotypes. The prompts tried to communicate location through clothing and appearance instead of capture conditions and environmental evidence. The images felt like tourism posters rather than moments.

Version 3 moved the work back to what the camera can observe: a specific body pose, a personal outfit, three scene cues, and a defined light direction. Instead of “sitting on a sofa,” we wrote “sitting sideways on the arm, one leg dangling, the other tucked up, head tilted slightly.”

That change made the scenes more specific without claiming that one look represents a city or group.

The Ten Scenario Prompts and Outputs

Every output below was generated at 1856 × 2304 using Nano Banana 2 in Masonry. Use the prompts as structural examples. Replace the fictional subject and décor with your own consented creator direction and campaign details.

São Paulo Bedroom at Golden Hour

iPhone selfie of a woman in her early 20s lying back on a bed in a modern São Paulo apartment bedroom at golden hour, propped up on one elbow, body turned toward the camera, phone held up in her other hand capturing herself from slightly above. Deep sun-kissed olive skin with warm bronzed undertone, dewy luminous texture, natural pores, golden flush on cheekbones. Deep espresso brown long hair loose and fanning out naturally on the pillow behind her. Soft confident expression, lips slightly parted in a relaxed almost-smile, direct warm gaze into the camera lens. Dewy bronzed makeup, terracotta eyeshadow, peachy blush, nude-brown glossy lips. Wearing a matching two-piece satin co-ord set in deep burnt sienna — thin-strap crop camisole and high-waist wide-leg satin trousers, fabric pooling and catching golden light around her reclining body. Delicate layered gold chain necklaces at collarbone. Background: plush linen bed with terracotta throw pillows, rattan pendant light above, potted indoor palm. Warm directional golden hour sunlight from a side window. Intimate relaxed bedroom UGC influencer selfie energy.

Why this works: The reclining pose with phone held up creates plausible selfie geometry. The satin fabric “pooling and catching golden light” gives the model specific texture instructions. Terracotta pillows, a rattan pendant, and an indoor palm establish one coherent palette and setting.

Saint Petersburg Marble Bathroom Morning

Bathroom mirror selfie of a woman in her mid-20s standing in a luxury Saint Petersburg marble bathroom at early morning, holding her smartphone up with one hand capturing her full reflection, face clearly visible and front-facing in the mirror. Naturally pale porcelain skin with cool undertone, slight tiredness under eyes, real fine skin texture with visible pores. Striking ice blue almond-shaped eyes with thin precise brown liner. Platinum blonde shoulder-length hair in a fresh slightly-slept-on blowout, one side tucked behind ear. Direct and unbothered expression, slight knowing smirk, one eyebrow barely raised, effortless cool-girl morning energy. Soft mauve lip stain, brushed-up natural brows. Wearing an oversized structured camel wool blazer worn as a dress, belted loosely at waist with a thin gold chain belt, hem falling mid-thigh, one sleeve pushed up revealing a vintage gold watch. White fluffy slippers. Small gold huggie hoop earrings. Smartphone visible in her raised hand in the mirror reflection. Background in mirror: white and grey veined marble walls, floating double vanity with matte black fixtures, backlit mirror, folded white towels on matte black rail. Cool diffused flat morning daylight from above.

Why this works: "Slight tiredness under eyes" and "slightly-slept-on blowout" push the image away from a polished headshot default. The blazer, chain belt, and slippers also combine dressed and at-home cues in one frame.

Brooklyn Sunday Afternoon

Candid lifestyle shot of a woman in her late 20s lying sideways across a wide cream boucle sofa in a Williamsburg Brooklyn apartment on a late Sunday afternoon, body fully reclined along the sofa length, head propped up on one hand with elbow on the sofa arm, other hand resting loosely on her hip, legs stretched out and slightly bent, looking directly at the camera with a genuine relaxed smile. Medium warm beige skin with golden undertone, prominent natural freckles densely scattered across nose and cheeks, slight sun flush, real visible pores. Green eyes with warm amber flecks, slightly squinting in the afternoon light. Dark brown hair with sun-bleached auburn ends in a messy high bun with many loose strands falling around her face. Just tinted SPF letting all freckles show, warm bronzer, clear lip gloss. Wearing a vintage oversized dark brown leather bomber jacket worn open over a cropped sage green ribbed tank, low-rise wide-leg cream linen trousers, woven brown belt. Layered thin gold chains, small signet ring on pinky, tortoiseshell sunglasses pushed up on head. Bare feet visible at the end of the sofa. Shot from coffee table level looking across at her full reclining pose. Background: cream boucle cushions, chunky knit throw, abstract art print on white wall, rattan lamp, trailing pothos.

Why this works: “Prominent natural freckles densely scattered” and “just tinted SPF letting all freckles show” reinforce the same visible trait. “Shot from coffee table level looking across” is more specific than a default eye-level portrait.

Paris Bedroom

Candid lifestyle shot of a woman in her early 20s sitting cross-legged on a low platform bed in a minimalist Paris apartment bedroom on a warm afternoon, leaning slightly forward with both hands resting in her lap, chin tilted down slightly, looking up at the camera with a quiet knowing expression and closed-lip half-smile, completely at ease. Fair skin with cool neutral undertone, slightly peachy at cheeks, smooth refined fine pore texture, faint natural flush. Deep warm brown slightly heavy-lidded eyes defined by clean thin black liner. Dark chocolate brown jaw-length choppy textured French bob falling naturally. Classic red matte lip as the hero, strong defined brow, thin black liner flick, minimal blush. Wearing a fitted black ribbed long-sleeve mock-neck bodysuit tucked into a perfectly tailored high-waist camel midi skirt with a centre-front split. Small gold stud earrings, single thin gold bangle. Black pointed-toe kitten heel mules placed beside the bed visible in frame. Background: ivory linen duvet and black accent pillow, white oak herringbone floor, tall arched window with warm Paris afternoon light, single sculptural vase on bedside table.

Why this works: "Classic red matte lip as the hero" — one bold choice, everything else minimal. The single bold lip color gives the otherwise minimal styling a focal point. "Kitten heel mules placed beside the bed visible in frame" tells a story: she took her shoes off to sit on the bed.

Mumbai Apartment at Dusk

Candid lifestyle shot of a woman in her mid-20s sitting sideways on the arm of a modern sofa in a curated South Mumbai apartment living room at dusk, one leg dangling down and the other tucked up, leaning back slightly with one hand resting on her raised knee and the other hand lightly touching her collarbone, head tilted slightly, looking directly at the camera with a warm magnetic half-smile and lifted chin. Rich warm medium-brown skin with deep golden undertone, natural healthy sheen, real skin texture with visible pores, small beauty mark near left jawline. Deep dark brown large expressive eyes with smudged kajal on waterline, soft bronze shimmer on lid, natural full lashes. Deep black thick hair blown out voluminously in a side-part past shoulders. Wearing a sharply tailored double-breasted cropped matte black blazer with gold buttons, deep V framing collarbone and décolletage, matched with high-waist wide-leg black tailored trousers. Chunky gold chain bracelet, gold sculptural ear cuff on left ear, thin gold hoops on right, delicate chain at collarbone. Gold strap heeled mule on her dangling foot. Shot from slightly below eye level looking up at her seated on the sofa arm. Background: cream plaster wall with large modern abstract canvas, designer amber floor lamp glowing, Mumbai city lights beginning through floor-to-ceiling glass at blue hour. Warm amber interior light from floor lamp camera-right, cool blue dusk from glass window camera-left, cinematic warm-cool split.

Why this works: "Shot from slightly below eye level looking up" — a power angle that makes the subject look commanding. The warm-cool light split creates cinematic depth. "Gold sculptural ear cuff on left ear, thin gold hoops on right" — mismatched earrings are a real fashion choice, not a prompt error.

Rainy Seoul Evening

Candid lifestyle shot of a woman in her early 20s sitting on the floor of her Hannam-dong Seoul apartment bedroom on a rainy weeknight evening, back leaning against the side of the low platform bed, knees pulled up to her chest, one hand loosely wrapped around her knees and the other hand raised with fingers lightly touching her cheek, head tilted sideways with a soft knowing smile looking directly into the camera, completely at ease. Porcelain skin with natural cool-pink undertone, subtle texture on cheeks, real and unairbrushed. Dark brown-black slightly monolid eyes, thin smudged brown pencil liner, natural lashes with one coat brown mascara. Glossy black hair long past shoulders, center-parted, one side tucked behind ear revealing a small sculptural silver ear cuff. Dewy cushion foundation, soft peach cream blush on apples of cheeks and nose tip, gradient rose lip tint fading from center outward. Wearing a matching oversized oat cream chunky ribbed knit two-piece lounge co-ord — boxy cropped crewneck pullover and matching high-waist wide-leg knit trousers. One silver ring on index finger. Fluffy ivory knit socks. Shot from a low angle at floor level looking across at her sitting against the bed. Background: dark wood platform bed behind her, tall arched black floor lamp with warm amber glow, large window showing rainy Seoul street with neon Hangul signs reflecting on wet pavement in soft bokeh. Warm amber floor lamp glow from camera-right, cool blue-pink neon from rainy window camera-left, cinematic colour split.

Why this works: "Gradient rose lip tint fading from center outward" gives the model a precise makeup transition instead of a generic color. The reflected Hangul signs, wet pavement, knit co-ord, and socks carry the rainy evening mood across foreground and background.

Amalfi Villa Bathroom

Candid lifestyle shot of a woman in her mid-20s sitting on the edge of a marble bathroom vanity counter in a contemporary Amalfi villa bathroom on a mid afternoon, legs crossed at the ankle dangling off the counter, one hand flat on the counter beside her supporting her weight, other hand resting lightly in her lap, leaning slightly back and looking directly into the camera with a warm open smile, lips parted, completely natural and effortlessly beautiful. Warm golden-olive deeply sun-kissed Mediterranean complexion, smooth with warm natural glow, subtle pore texture, light sun-touch across nose and cheeks. Warm hazel eyes with strong green and amber tones. Deep dark brown long hair in loose romantic dark curls past chest, natural volume and sea-salt texture. Sheer foundation, terracotta and bronze eyeshadow, coral blush, nude coral gloss lips. Wearing a plunging wrap mini dress in fluid deep burgundy satin with thin self-tie straps, hem riding up slightly as she sits on the counter, bare golden-olive legs dangling. Thin delicate gold chain necklace, small gold hoop earrings. Strappy gold flat sandals on her dangling feet. Background: white Calacatta marble walls with grey veining, brushed gold fixtures, fluffy white towels on gold rail, small bud vase with eucalyptus stems, frosted window with warm diffused Mediterranean light.

Why this works: “Hem riding up slightly as she sits on the counter” specifies how the clothing responds to the pose. “Sea-salt texture” adds a tactile hair cue. Calacatta marble, brushed gold fixtures, and eucalyptus stems keep the bathroom styling internally consistent.

Notting Hill in Autumn

Candid lifestyle shot of a woman in her mid-20s sitting on the floor of a Notting Hill London apartment living room on an overcast autumn afternoon, back resting against the front of a low greige boucle sofa, legs stretched out and crossed at the ankle, one hand holding a ceramic mug resting on her knee, the other hand pushing her hair back from her face mid-gesture, looking at the camera with a quiet amused smile caught mid-moment, effortlessly composed. Light neutral skin with cool peachy undertone, very faint freckles on nose and upper cheeks, fine pore texture, slight rosy flush. Blue-grey clear eyes. Strawberry blonde hair past shoulders in loose natural waves. Wearing a fitted square-neck camel ribbed knit midi dress with structured square neckline, full collarbone exposed, form-fitting ribbed fabric falling to mid-calf, tan leather belt at natural waist. Pearl drop earrings, thin gold watch. Brown leather pointed-toe loafer flats beside her on the floor. Background: greige boucle sofa behind her, cream plaster wall, stack of coffee table books beside her, tall window with overcast grey London light, warm amber side lamp glow. Diffused cool overcast light from window balanced with warm amber lamp.

Why this works: “The other hand pushing her hair back from her face mid-gesture” turns the pose into a caught moment. The mug, book stack, shoes, cool window light, and warm lamp create a readable before-and-after story without relying on one prop.

Mexico City Mirror Selfie

Bedroom mirror selfie of a woman in her early 20s standing in front of a full-length mirror in a Colonia Roma Mexico City apartment bedroom on a warm afternoon, holding her smartphone up in one hand at a slight downward angle, other hand resting on her hip with a confident stance, looking directly into the camera with a wide radiant smile and bright warm eyes. Warm medium-tan skin with rich golden-copper undertones, vibrant and full of life, smooth healthy natural warmth. Deep warm dark brown large expressive eyes dramatically framed by full lashes and bold liner. Rich dark black-brown long hair past chest, thick and voluminous, half-up half-down with top section loosely pulled back. Bold full lashes, warm terracotta-brick eyeshadow, vibrant coral-orange bold lip. Wearing a matching white embroidered off-shoulder co-ord set — fitted off-shoulder crop top with floral embroidery in bright coral, yellow, and green, wide elasticated neckline pulled below both shoulder joints, paired with matching high-waist wide-leg white linen trousers with the same embroidery along the hem. Multiple layered gold choker necklaces, large gold hoop earrings. Bare feet on warm terracotta tile floor. Smartphone visible in her raised hand in the mirror. Background in mirror: terracotta-painted bedroom wall, low rattan bed frame with bright woven blanket, hanging macramé wall art, Mexican ceramic vases, dappled warm afternoon light through sheer curtain casting leaf shadow patterns.

Why this works: The bright embroidery repeats against a restrained white outfit, while the terracotta wall and tile keep the palette coherent. "Dappled warm afternoon light through sheer curtain casting leaf shadow patterns" gives the model specific light behavior to render.

Copenhagen Kitchen Morning

Candid lifestyle shot of a woman in her mid-20s standing barefoot in a minimal Copenhagen apartment kitchen on a soft cool morning, leaning with her back against the kitchen counter, both hands loosely wrapped around a large ceramic coffee mug held at chest height, head slightly tilted and looking directly at the camera with a barely-there soft smile and serene morning calm, completely present and unhurried. Fair cool skin with faintest pink undertone, very smooth fine skin texture, slight natural pink flush along cheeks. Grey-blue clear sharp eyes set wide apart. Ash blonde long hair past shoulders in a loose effortless low bun at nape, several face-framing pieces left loose. Barely-there sheer dewy coverage, clean thin brown mascara only, minimal natural brow, very sheer natural rose blush, clear lip balm, minimal no-makeup look. Wearing a matching oversized oat-white premium modal knit two-piece lounge co-ord — relaxed wide-neck long-sleeve top with dropped shoulders and matching high-waist wide-leg knit trousers. No jewellery. Barefoot on warm white oak herringbone wood floor. Background: white oak cabinetry with brushed brass handles, poured concrete countertop, open cookbook on the counter, large arched window flooding cool Scandinavian morning daylight, single sculptural dried flower arrangement in a ceramic vase.

Why this works: "No jewellery" is as important as any positive instruction — it tells the model to leave something out, which keeps the frame quiet. "Completely present and unhurried" is a mood instruction that affects the entire composition.

The Eight Rules That Survived the Iterations

After more than 28 generations and three prompt rewrites, these were the most useful rules for this set:

  1. Lead with capture geometry. “iPhone front camera from slightly above” and “shot from coffee-table height” change the composition more reliably than generic quality adjectives.
  2. Describe the body in space. Replace “sitting on a couch” with the location of the torso, hands, elbows, knees, and gaze. Use a pose you could reproduce physically.
  3. Use observable texture, not flaw language. Choose two or three details such as visible pores, freckles, fabric weave, flyaway hair, or a soft under-eye shadow. More is not automatically better.
  4. Write a person, not a demographic. Wardrobe, expression, and personality belong to the fictional subject and moment. Nationality is not an art-direction shortcut.
  5. Give props a narrative job. A mug in both hands, shoes beside the bed, or an open book on the counter implies an action before or after the frame.
  6. Name the light sources. State direction and temperature: cool window light from camera-left, warm lamp from camera-right. Do not add a second source merely to sound cinematic.
  7. Keep constraints short. Three clear constraints in the prompt usually outperform a paragraph of “no” instructions. Ask for a coherent frame, then reject failures.
  8. Change one layer at a time when diagnosing. Hold capture and subject constant while testing the pose, scene, or light. Rewrite the whole brief only when the concept itself is wrong.

Reject Bad Outputs Before You Publish

The images in this article are polished enough to illustrate the method, but a good-looking portrait can still fail a campaign. Review each candidate at full size:

CheckReject when
AnatomyFingers merge, joints bend implausibly, teeth repeat, or eyes point in different directions
Capture geometryThe arm, mirror, phone, camera height, or reflection could not have produced the frame
Identity continuityFace shape, age, hairline, marks, or other stable traits drift across the set
Product truthPackaging, logo, color, texture, size, or product use differs from the real item
EnvironmentText is garbled, architecture breaks, props float, or light and shadows disagree
Channel fitThe crop hides required disclosure or key product information on the target placement

Track acceptance rate, not just the prettiest generation. If you make 20 images and only two survive review, that is a 10% acceptance rate and a very different production cost from the list price of one generation.

Use Synthetic Creators Without Faking Endorsements

These images depict fictional adults. That does not make every commercial use truthful.

  • Do not invent first-person product experience, results, customer reviews, or testimonials for a synthetic persona.
  • Get permission before using a real person's face, voice, identifying traits, or reference photos.
  • Make the synthetic nature clear when a reasonable viewer could otherwise believe the depicted person or event is real. Channel and jurisdiction rules vary, so have production campaigns reviewed for the markets where they run.
  • If content endorses a brand, disclose material connections clearly and with the endorsement itself. The US Federal Trade Commission's Disclosures 101 and Endorsement Guides resources are the starting point for US campaigns.

The FTC guidance is about truthful endorsements and clear disclosure of material relationships; it is not a blanket statement that one specific AI label makes every synthetic ad compliant.

Start Building Your Own Feed

The prompts are patterns to adapt, not demographic templates to copy. Start with one consented fictional creator direction, four candidates, and the rejection checklist. When one image passes, add a second scene with the same references and stable traits. Build the set only after continuity holds.

All people depicted in this post are synthetic outputs generated using Nano Banana 2 via Masonry; no person sat for these photographs.

FAQ

Questions from this guide

Concise answers to the questions readers ask after this guide

How do I make AI UGC photos look less like stock photography?

Specify the capture device and angle, place the body precisely in the scene, describe a few observable skin and fabric details, add lived-in environmental cues, and define where the light comes from. Then reject anatomical errors, inconsistent identity, unreadable products, and implausible reflections instead of trying to fix every problem with a longer prompt.

Can I keep the same AI creator consistent across multiple photos?

Yes, but text alone is unreliable. Use two clear reference images of a fictional adult persona, keep the stable identity traits short, and vary only the scene, pose, wardrobe, and lighting. Review every output because reference-guided generation can still drift.

Which model were these AI UGC photos made with?

The 13 outputs shown in this article were generated with Nano Banana 2 in Masonry. They are examples from one iterative prompt set, not a benchmark proving that the model will win on every creator, product, or campaign.

Do AI influencer ads need disclosure?

Do not use a synthetic persona to fabricate product experience or a customer testimonial. In the United States, endorsements must be truthful and material connections must be clearly disclosed. Whether an additional AI label is required depends on the content, channel, audience, and applicable law; get legal review for production campaigns.
