Objetivo
Crear personas que no existen y que nadie identifica como IA, con 5 prompts listos para copiar. El truco no es pedir más calidad: es pedir la belleza por un lado y la cámara mala por el otro.
El error que comete casi todo el mundo
Pedir "ultrarrealista, 4K, calidad profesional".
Eso te devuelve una foto de estudio impecable: iluminada perfecto, encuadrada perfecto, piel perfecta. Y eso es exactamente como se ve la IA. La perfección es la que te delata.
Los dos ejes que hay que pedir por separado
Aquí está todo el truco, y es lo único que de verdad importa de esta guía:
- La persona sube. Belleza nivel modelo: pómulos altos, mandíbula definida, rasgos simétricos, ojos grandes y separados, labios llenos, cejas pobladas.
- La foto baja. Selfie de celular: flash directo, encuadre torcido, ruido digital en las sombras, un cuarto real desordenado de fondo, piel grasosa.
La belleza la pone la persona. El realismo lo pone la cámara mala. Si mezclas los dos ejes —gente común fotografiada bien— sale algo creíble pero sin gancho; y gente guapa fotografiada bien sale como anuncio de banco.
La frase que amarra las dos cosas, y que va en los cinco prompts:
the face of someone signed to a modelling agency — but the photo itself is still a careless phone selfie.
Los 5 prompts
1. Ella en su cuarto, con flash de noche
El flash directo es el que más engaña: aplana la cara, quema los brillos y tira la sombra dura contra la pared.

$ A young Latin American woman, around 24, lying on her side on an unmade bed in her bedroom at night, resting her cheek against her closed fist, looking straight into the phone camera with a flat neutral expression, lips slightly pushed forward.
HER: warm medium-brown skin, long dark straight hair with a middle part, a few strands stuck to her cheek. Thick natural dark eyebrows, slightly uneven. Sharp black winged eyeliner, a little smudged at the outer corner. Glossy lips with visible shine and a small highlight. A tiny dark beauty mark below her left eye. She wears a black thin-strap top and a beaded bracelet on her wrist.
BEAUTY — she is strikingly beautiful, model-tier: high sharp cheekbones, a defined jawline, a small straight nose, very large almond dark-brown eyes set wide apart, long dense lashes, and naturally full lips. Symmetrical face with delicate features. Slim neck and shoulders. She has the face of someone signed to a modelling agency — but the photo itself is still a careless phone selfie.
THE LIGHT: harsh DIRECT ON-CAMERA FLASH at night. The flash flattens her face, blows out the highlights on her forehead, nose and cheekbones, and throws a hard dark shadow of her head and arm onto the beige wall right behind her. Everything beyond her falls off into darkness fast.
THE PLACE: her own bedroom. Plain warm-beige wall, a curtain edge visible at the right, rumpled cream bedsheets in the foreground, slightly out of focus.
This must look like a REAL AMATEUR SELFIE taken on a phone by the person themselves — NOT a professional photograph, NOT a studio portrait, NOT a rendered image. The imperfection is the point.
MANDATORY REALISM MARKERS: skin is unretouched and slightly oily — visible shine on the forehead, nose and chin, matte elsewhere. Open pores clearly visible on the nose and cheeks. Fine translucent peach fuzz along the jaw catching the light. Natural asymmetry in the face and eyebrows. A few stray flyaway hairs standing up out of place. Faint redness around the nostrils and inner eye corners. Real skin texture with tiny blemishes, nothing covered up.
PHONE CAMERA LOOK: shot at arm-s length on a phone front camera. Slightly wide-angle distortion typical of a selfie lens. Imperfect casual framing, subject not perfectly centred, head close to the top edge. Very slight handheld softness, mild digital noise in the shadows, and the flat compressed look of a phone sensor. No shallow depth of field from a fast lens, no professional bokeh, no colour grading.
Absolutely no text, no captions, no logos, no watermarks, no graphics anywhere in the frame.2. Ella en el pasillo, con poca luz
Aquí manda el ruido digital y el tinte verdoso del sensor peleando con la penumbra. Un cuarto real de fondo.

$ A young Latin American woman, around 22, taking a selfie standing in the hallway of her home at night, head tilted slightly back, chin up, looking down into the phone camera with a serious, unbothered expression.
HER: olive-tan skin with a natural sheen, very long dark brown hair falling loose over both shoulders, slightly frizzy with visible flyaway strands lit from behind. Strong groomed dark eyebrows. Full lips with a glossy nude tint. A thin silver chain necklace with a small butterfly pendant resting on her chest. A white lace-trimmed top.
BEAUTY — she is exceptionally beautiful in a striking, editorial way: sculpted high cheekbones, a long elegant neck, a straight refined nose, wide-set light-hazel eyes under strong arched brows, and very full lips. Sharp, model-like bone structure that reads even in bad lighting. Slim, long-limbed. The face of a runway model — but the photo is still a grainy low-light phone selfie.
THE LIGHT: dim indoor ambient light plus a weak phone flash, giving a slightly cool cast and a greenish tint typical of a phone shooting in low light. Noticeable digital noise in the darker areas. Highlights on her forehead, nose and collarbones read wet and shiny.
THE PLACE: a home hallway — a painted blue door behind her, white ceiling and cornice visible at the top of the frame because the phone is held low, a corner of a cluttered room visible at the left edge.

El más contundente: a esa distancia se ven los pelos de la barba uno por uno y la yema del dedo pálida por la presión.

$ EXTREME CLOSE-UP selfie of a young Latin American man, around 27, filling almost the entire frame with his face, tilted at an angle. He is pointing his index finger at his own cheek, touching the skin. He looks into the camera with a deadpan expression.
HIM: light-tan skin, wavy dark brown hair falling over his forehead with one curl hanging loose. Very thick dark eyebrows. Brown eyes. Heavy dark stubble across his jaw, chin and upper lip — individual hairs clearly visible, uneven growth, some longer than others on the neck. Slight redness on the cheek where his finger presses the skin, and the fingertip goes pale from the pressure. A thin gold chain necklace. Bare shoulders.
BEAUTY — he is extremely handsome, male-model tier: a strong square jawline, sharp cheekbones, a straight nose, deep-set expressive brown eyes under thick dark brows, and a defined cupid's bow. Symmetrical, chiselled features. Broad shoulders and a lean athletic build with visible definition in the neck and trapezius. The face of a Calvin Klein campaign — but the photo is still a careless phone selfie.
THE LIGHT: bright natural daylight from an open terrace, hitting one side of his face hard and leaving the other in soft shadow. The bright light exaggerates the shine on his nose and the texture of his stubble and pores.
THE PLACE: an outdoor terrace of a house — wooden slat ceiling above him, a doorway and a hanging rattan lamp visible far behind, all thrown out of focus.
This must look like a REAL AMATEUR SELFIE taken on a phone by the person themselves — NOT a professional photograph, NOT a studio portrait, NOT a rendered image. The imperfection is the point.

Luz suave de ventana, sin flash. El brazo estirado dentro del cuadro y las pecas dispersas de forma irregular.

$ A young Latin American woman, around 25, taking a selfie standing in a hotel room in the morning, one arm extended toward the camera, body angled, looking into the lens with a soft neutral expression.
HER: warm tan skin with a dense scattering of natural freckles across her nose and cheeks, irregular and asymmetric. Long dark brown wavy hair, slightly messy with a visible halo of frizz. Very full dark eyebrows. Long natural lashes. Soft pink-nude lips. She wears a cream linen slip dress and a chunky gold bangle on her wrist.
BEAUTY — she is stunning in a natural, sun-kissed way: high cheekbones dusted with freckles, a defined jawline, a small upturned nose, large hooded brown eyes with long lashes, and full soft lips. Perfectly symmetrical features and a slim toned figure with defined collarbones and shoulders. The face of a beauty campaign — but the photo is still an offhand phone selfie.
THE LIGHT: soft indirect daylight coming through a window off-frame, no flash. Even and gentle on her face, with the shine of the morning on her forehead and cheekbones.
THE PLACE: a real hotel room — an unmade bed with white pillows behind her at the left, a fabric-panelled headboard, a black reading lamp on the wall, a wooden wardrobe and tiled floor at the right. Everything slightly out of focus but clearly a lived-in room.

El teléfono abajo apuntando hacia arriba: distorsiona un poco la cara y mete el techo en el encuadre. Muy de selfie real.

$ A young Latin American man, around 28, taking a selfie from a LOW ANGLE inside a large industrial gym, holding the phone below chest height and pointing it up at himself, so the ceiling structure fills the top of the frame. He is looking off to his right, not at the camera, with a calm serious expression.
HIM: light-tan skin, thick wavy dark-brown hair pushed back and slightly messy from training, a few strands falling loose over his forehead. Heavy dark stubble across his jaw and upper lip. Over-ear black headphones on. A plain black t-shirt, fitted, slightly damp at the collar.
BEAUTY — he is extremely handsome, male-model tier: a strong square jawline, sharp cheekbones, a straight nose, deep-set brown eyes under thick dark brows, and a defined cupid's bow. Symmetrical, chiselled features. Broad shoulders and a lean athletic build with visible definition in the neck and shoulders. The face of a fashion campaign — but the photo is still a careless phone selfie.
THE LIGHT: cold overhead fluorescent tube lights running along the white beamed ceiling, plus daylight leaking from a window at the right. Slightly flat, unflattering top light that leaves faint shadows under his eyes and picks out the sweat sheen on his forehead, neck and collarbones.
THE PLACE: a big open industrial gym — white painted wooden ceiling with exposed black steel trusses, long fluorescent tube fixtures, a window with blue light at the right edge. Everything behind him slightly out of focus.
This must look like a REAL AMATEUR SELFIE taken on a phone by the person themselves — NOT a professional photograph, NOT a studio portrait, NOT a rendered image. The imperfection is the point.
MANDATORY REALISM MARKERS: skin is unretouched and slightly oily — visible shine on the forehead, nose and neck. Open pores clearly visible on the nose and cheeks. Fine peach fuzz along the jaw. Natural asymmetry in the face and eyebrows. Stray flyaway hairs out of place. Faint redness at the nostrils. Real skin texture with tiny blemishes, nothing covered up.
PHONE CAMERA LOOK: shot at arm-s length on a phone camera held low. Slight wide-angle distortion from the low angle. Imperfect casual framing, subject off-centre. Very slight handheld softness, mild digital noise in the shadows, the flat compressed look of a phone sensor. No shallow depth of field, no professional bokeh, no colour grading.
Absolutely no text, no captions, no logos, no watermarks, no graphics anywhere in the frame.El bloque que se repite en los cinco

- El lugar importa más que la cara. Una cama deshecha, una puerta pintada, un pasillo con cosas encima: eso es lo que convence. Un fondo liso de estudio te delata al instante.
- Pide el defecto por su nombre. "Piel realista" no hace nada. "Brillo grasoso en la frente y la nariz", "pelos parados fuera de lugar", "ruido digital en las sombras" sí.
- Nada de bokeh. El desenfoque bonito de lente rápido es la marca más clara de foto profesional. Pide explícitamente que no lo haya.
- La sombra del flash. Cuando pidas flash de noche, pide también la sombra dura del sujeto sobre la pared de atrás. Es el detalle que más vende la escena.
- Cambia el país y la edad. Los prompts dicen Latin American; cámbialo por lo que necesites. Todo lo demás funciona igual.
