Domina Nano Banana 2: De una Selfie a una Portada de Revista

¿La Inteligencia Artificial puede realmente replicar el ojo de un fotógrafo profesional?
Hace apenas unas semanas aterrizó Nano Banana 2 y la industria de la generación de imágenes ha dado un giro de 180 grados. Ya no se trata solo de escribir un texto y esperar lo mejor; se trata de aplicar criterios reales de composición, iluminación y óptica para obtener resultados que, sinceramente, me han dejado sin palabras.
En este artículo (y en el video que verás a continuación), he querido ir más allá de los tutoriales básicos. He tomado mis propias fotografías —esas que podrías hacer con una Sony A7IV o incluso con tu móvil— y las he pasado por el filtro de Nano Banana 2 utilizando mi «Gen de Prompts» personal.
Lo que vamos a explorar hoy:
El Test del Realismo: ¿Puede la IA imitar el bokeh y la textura de un lente de 85mm f/1.8?
Estilo Editorial: Cómo transformar una captura urbana en una producción de moda de alto nivel.
Flujo de Trabajo Híbrido: Uso de imágenes de referencia para mantener tu esencia mientras la IA potencia la creatividad.
El Secreto de los Prompts: Por qué los «prompts» que ves en Instagram no siempre funcionan y cómo corregirlos.
Si eres fotógrafo, editor o simplemente un apasionado del arte visual, este flujo de trabajo va a cambiar la forma en que ves la creación de contenido.

El rostro es sagrado y no se puede modificar.Reglas de Creación Adicionales (Aplica siempre estos elementos a la idea del usuario):Anatomía Perfecta: Incluye instrucciones para evitar deformaciones ("no body deformations, realistic human proportions, correct anatomy").Microdetalles: Describe la textura de la piel (poros visibles, imperfecciones naturales), humedad (gotas de agua, sudor, reflejos) y texturas de la ropa de forma táctil.Composición: Estructura la escena en 3 planos (primer plano con elementos desenfocados/bokeh, sujeto enfocado en el plano medio, fondo atmosférico).Iluminación: Describe luces cinematográficas (luz clave, rim light, catchlight en los ojos, iluminación de estudio o dramática) y atmósfera (humo, partículas de polvo, nieve, lluvia, neón).Cámara y Óptica: Especifica equipos de alta gama (ej. lente de 85mm f/1.2 o f/1.4, estilo Fujifilm o Leica, enfoque nítido, profundidad de campo ultrarreducida, grano fílmico orgánico).Formato de Salida:Cada vez que el usuario te dé una idea, debes responder EXCLUSIVAMENTE con lo siguiente:Prompt en Inglés (Optimizado para IA): Un bloque de texto coherente, rico en palabras clave y separado por comas, listo para copiar y pegar.Prompt en Español: La traducción exacta del prompt para que el usuario sepa qué va a generar.Negative Prompt: Sugerencia de palabras clave negativas para asegurar la anatomía y la fidelidad (ej. extra fingers, plastic skin, CGI, deformed, changed facial features, altered face).
Prompts usados en el video
Aquí tienes la recopilación de todos los prompts en inglés que hemos trabajado. Los he organizado con títulos descriptivos para que luzcan perfectos y profesionales como una «Galería de Prompts» o «Biblioteca de Estilos» en tu página web.
1. Cinematic Night Fashion (Mustang & Neon Rain)
Un retrato urbano nocturno con una fuerte atmósfera cinematográfica, reflejos de lluvia y estilo automovilístico vintage.
«A cinematic night fashion editorial portrait of an adult man. Do not change my face; ensure no body deformations, maintaining realistic human proportions and correct anatomy. He is sitting on the hood of a vintage 1969 Ford Mustang parked outside a restaurant at night. The front of the car and the Mustang identity are unmistakable: the Mustang pony emblem/logo is very clear and prominent on the grille/hood area. He is looking to the side, not really smiling, slightly looking downward, with less light falling on his face (moody shadowed face). He wears a black leather trench coat. There is smoke drifting in from the side, rain reflections shimmering on the asphalt, strong red neon glow from nearby signage, wet street atmosphere, cinematic night mood. Shot style: Fujifilm X-T5 look, 85mm f/1.2 portrait lens effect, shallow depth of field, sharp subject, soft background bokeh. Testino lighting style, dramatic contrast, glossy highlights on leather coat and wet car paint, ultra-realistic, ultra-detailed photorealism, visible skin texture, pores, raindrops and reflections.»
2. Ultra-Realistic Wet Skin & Fine Details
Un primer plano hiperrealista centrado en la textura de la piel húmeda, microdetalles, gafas de sol y proporciones perfectas de las manos.
«An ultra-realistic cinematic close-up portrait of a young man (using the shape and face from the reference) with glistening, damp, wet skin and light rain falling naturally on his forehead. Fine water droplets cling to his face and hair, enhancing skin texture and moisture realism. He wears sleek square black sunglasses, lightly touched by his fingertips; tiny water droplets are visible on the lenses, catching light highlights. Dramatic low-key lighting with deep shadows sculpts the face, accentuating sharp cheekbone structure, intense eyes, and skin micro-details. The lighting creates cinematic contrast with soft reflections on the sunglasses. He wears a black turtleneck sweater that blends seamlessly into a minimalist dark background, keeping the focus entirely on the face and hand gesture. Hands are highly detailed: defined knuckles, slender fingers, natural visible veins, clean nails, and a metallic silver ring with a black stone on one finger. Shot with an 85mm lens at f/1.4, ultra-shallow depth of field, razor-sharp focus on eyes, fingers, and water droplets. High contrast, tactile texture, fashion editorial photography aesthetic, hyper-realistic precision, cinematic mood, premium high-end magazine finish.»
3. Cosmic Beauty Macro (Universe & Water)
Fotografía high-end beauty de estudio, mezclando elementos surrealistas sutiles (el universo en el ojo) con realismo extremo en la piel y el agua.
«Universe – deep cosmic blue tones, dark violet, subtle nebula reflections, and small luminous nuances resembling galaxies, yet elegantly and believably integrated into the eye, without appearing artificial. Thick, dark, highly defined eyebrow; sharp eyelashes. Real skin with visible pores, enhanced micro-textures, small natural pigmentations, and a sophisticated organic finish. Natural lips with delicate texture. Subtle facial hair preserved. Dark, slightly damp hair with organic strands near the forehead. Water flowing vertically over half the face with a totally realistic, crystalline, clean, transparent, and physical appearance, like pure water photographed in a high-end studio, with natural gloss, delicate refraction, coherent thickness, and well-defined droplets. No magic effect, no fantastical coloring in the water. Premium extremely soft and diffused studio beauty lighting. Elegant catchlight in the eye. Refined local contrast, subtle three-dimensionality on skin and water. Clean and sophisticated color grading in neutral-cool tones with naturally slightly warmed skin. Clear, minimal, quiet background. Aesthetic of an international luxury skincare editorial advertising campaign. Hyper-realism, ultra-sharp, micro-details preserved, no oversharpen, no noise, no plastic skin, no excessive retouching. High-end beauty photography, 85mm macro lens look, shallow and precise depth of field, critical focus on the iris, premium texture, impeccable finish, elegant, sensorial, and magnetic visual.»
4. Intimate Cinematic Editorial (Candlelight & Depth)
Una escena sofisticada en interiores reales, destacando el uso de tres planos de profundidad, luz de velas e iluminación cinematográfica cálida.
«A hyper-realistic single-frame editorial photograph of a person matching the reference image, posing in a poetic and contemplative manner, sitting on the floor in an intimate, sophisticated, and real environment that feels like a genuine living space rather than a studio. Composition: Cinematic three-plane depth. In the foreground, blurred organic elements very close to the lens, such as soft bokeh plant leaves and a partially visible candle with warm reflections creating natural depth. In the middle ground, the person as the absolute focus with a sensitive, elegant, and emotionally poised pose, refined styling, and poetic presence. In the background, naturally distributed candles, a discrete potted plant, and a subtly textured wall with a rich but balanced visual atmosphere. Lighting: Premium cinematic lighting with a soft directional key light mixed with the realistic warmth of candlelight. Very subtle fill light to recover details, and a striking, sophisticated rim light outlining hair, shoulders, and silhouette. Include delicate light beams passing through a nearby shutter, projecting subtle linear patterns on the floor and background as if from an off-frame side window. Technical Details: Realistic sharp reflections of warm candlelight on the floor and skin; credible physical optical behavior. Tiny, subtle airborne micro-particles catching the light poetically. Impeccable color grading with a premium vintage cinematic aesthetic, refined contrast, rich warm tones, deep blacks, soft halation in highlights, and delicate bloom on candle flames. Fine organic grain and professional optical sharpness. High-fashion atmosphere, luxurious, intimate, and extremely realistic.»
5. Urban Modern Art Music Poster
Un estilo diferente, más gráfico y enérgico, combinando fotografía con arte urbano, garabatos y tipografía.
«Edit this image into a modern art poster of a man immersed in his music—wearing a cap and wireless earphones, head slightly tilted as he feels the rhythm. Surround him with energetic scribbles in black, orange, and white: arrows, lightning bolts, sound waves, and abstract motion lines bursting from his head. Use a clean white or bright orange background to emphasize contrast and rhythm. Include bold graffiti-style text such as ‘ErtanLabs,’ ‘Sound Rush,’ and ‘Feel It.’ His jacket or hoodie should feature metallic textures or glowing lines to match the high energy of the composition. Professional graphic design aesthetic, high contrast, vibrant and rhythmic urban style.»
6. Dramatic Winter Snow Portrait (Face Replacement)
Un retrato en la nieve con instrucciones precisas para realizar un «Face Swap» o reemplazo de rostro manteniendo intacto el entorno original.
«Generate a photograph that replaces ONLY the face from Reference Image 2 with the face from the Face Reference Images provided. Exactly maintain the pose, framing, lighting, setting, and clothing from Reference Image 2. The new face must preserve natural proportions, facial alignment, gaze direction, and an expression compatible with the original pose, achieving realistic integration with the scene’s lighting. A dramatic and realistic photographic portrait in a heavy snow environment. Close-up framing of the face and upper torso, in a side profile facing to the right. The main focus is on the goggles area and the concentrated expression of the person looking into the distance. Snow goggles with a red frame and a slightly fogged transparent lens. They have accumulated snowflakes on the lens and the frame. The strap is red with a visible yellow oval logo on the side. A dark winter beanie covered by accumulated snow. A thick red winter jacket with durable fabric texture. Several snowflakes are scattered over it. The high collar is partially closed, protecting the neck. Cold and natural lighting, typical of a snowy environment, with bluish and grayish tones dominating the scene. Small snowflakes are falling in the air around, reinforcing the feeling of intense cold. Blurred background (bokeh) showing a mountain or forest environment covered in snow, creating cinematic depth of field.»
