Promts de Halloween

Los prompts te los pasamos en inglés porque es la mejor forma de conseguir que Gemini te entienda. Si tienes alguna duda, te animamos a usar el traductor de Google. Luego, simplemente debes ir detallando las instrucciones (‘ponme una mano aquí’, ‘que el payaso miré allá’…) hasta conseguir algo parecido a lo que buscas.

Siguiendo algunas de ellas yo mismo he podido crear esta foto con Art the Clown, de la saga Terrifier.

Tu foto con Jason

Si quieres aparecer unto al famoso asesino de Viernes 13,adjunta una foto tuya y usa este prompt con Gemini cambiando ‘woman’ por ‘man’ en caso de que seas chico y ajustando algunos detalles como el largo del pelo o la pintura de las uñas.

A grungy, realistic 80s-style cinematic close-up inside a cabin at Camp Crystal Lake. A young woman lies comfortably on Jason Voorhees’ lap, her expression cute, dreamy, and soft, with wide eyes and a gentle pout, preserving her exact facial features. Her long dark blonde wavy hair is parted in the middle, slightly messy, with two loose strands in front decorated with beads and tiny hair gems. She wears a vintage 80s camp counselor outfit: slim-fit shorts, a tucked-in ringer tee with the Camp Crystal Lake logo, tall striped socks, and retro sneakers with colorful laces. Accessories: layered bracelets, thin necklace, small hoop earrings, and a camp whistle on a cord. Makeup: brown lip liner with gloss. Jason Voorhees sits on the couch, wearing his exact movie-accurate outfit: weathered hockey mask, tattered work shirt, dark pants, and holding a machete at his side. His other hand rests gently on her, giving a cinematic, friendly, protective vibe. The camera angle is closer to focus on both faces, illuminating them clearly with soft lantern and moonlight, making expressions and hair details visible. The cabin is dimly lit with flickering lanterns, dusty windows, worn wooden floors, and scattered camping gear. The scene has grainy 80s film textures, muted tones, dramatic shadows, and realistic cinematic lighting, like a high-quality still from a classic Friday the 13th movie. Do not change her face.

Tu foto con Pennywise

Igual que antes, ajusta algunas directrices para lograr tu foto con el famoso payaso de IT.

Create a dreamy Y2K-style portrait set outside on a suburban sidewalk during rain, inspired by the 1980s IT movie. The scene features a curb-side drain, partially shadowed, with only Pennywise’s glowing eyes peeking out ominously. I am leaning toward the drain, looking curiously and slightly nervous at him, wearing a bright yellow rain jacket like Georgie, with the hood slightly up, capturing the suspense and iconic feel of the movie. Hair and makeup: My hair is long, soft, voluminous 1980s-style waves, slightly damp from the rain. My makeup is cute and Y2K-inspired: glossy lips, subtle eyeshadow, soft blush, youthful and dreamy. Outfit: The yellow rain jacket is paired with casual 1980s teen clothing underneath—high-waisted jeans and sneakers, muted tones, fitting naturally for a small-town street scene. Background and props: The wet sidewalk reflects dim street lighting, raindrops create soft streaks, puddles glisten, and scattered autumn leaves enhance the moody atmosphere. A few subtle red balloons float near the drain, hinting at Pennywise’s presence. Pennywise: The classic 1980s Pennywise lurks inside the drain, glowing eyes only visible, partially hidden in shadows, creating a dark, eerie, and suspenseful vibe. Lighting and style: Cinematic and moody with reflections in the wet pavement, soft dreamy Y2K highlights, and a slightly surreal glow that blends eerie horror with a whimsical, cinematic aesthetic.

Tu foto con Art

En este caso, te recomendamos que, además de una foto tuya, adjuntes una foto de Art the Clown para que Gemini no genere una imagen donde parezca un payaso ‘random’ totalmente diferente.

Create a dreamy Y2K-meets-grunge 90s style portrait of us in a 90s style pizzeria, the girl in the second photo should be sitting next to the guy in the first photo on a bench seat, the girl in first photos arm should be around him in a playful happy pose with her other arm up cellphone in hand taking a selfie together, shes wearing a black shirt with dark distressed jeans and a oversized black leather jacket, her long dark blonde hair falls freely in soft waves, wearing chunky yet fashionable jewelry, including dainty black and gold necklaces, bold accessories, and black and gold rings, nails are long, almond-shaped, and painted lime green. The room around them is classic 90s pizzeria but with a, mysterious, and moody feel, it should have tables with bench seats, it should look dirty with trash and left over food on the tables but decorated with 90s-style jewel-toned colors, dreamy glows across the dimly lit space. The man in the first picture should look exactly like the photo with the same facial expression Do Not change his appearance at all. The overall atmosphere should be both dreamy and grainy, combining the glamorous Y2K aesthetic with a grungy 90s alternative mood. Do not change their face. Do not change their facial features THE GUY IN PICTURE ONE SHOULD LOOK EXACTLY LIKE THE PHOTO. THE GIRL IN PICTURE TWO SHOULD LOOK LIKE HER PHOTO DO NOT CHANGE HER FACE.

Tu foto con el Creeper

El antagonista de Jeepers Creepers también tiene su ración de prompts en Gemini.

Cinema style portrait of me running through a creepy cornfield toward an old school bus, wearing a torn white crop top and baggy jeans, flawless skin, hair flowing in the wind, worried expression. Grainy photo style. A dark creeper figure with bat-like wings, hat, and trench coat chases from behind in the dimly lit field. Background dark, ominous, with stars and moonlight. Do not alter my face or facial features

Tu foto con Samara

Si quieres que Samara aparezca junto a ti en una foto, antes de que pasen los 7 días que te da de ventaja, usa este prompt.

Create an Ultra-realistic, cinematic horror portrait of me with Y2K flair. Main focus on me kneeling on the floor in front of a glowing TV, my hand hovering just above the old corded phone beside me, as if I am about to answer its insistent ringing. My face is fully illuminated by the TV’s static light, cute and dreamy with a soft, gentle, thoughtful expression—not smiling, but focused with subtle unease. My Y2K-style clothing and long flowing dark blonde hair match the 2002 The Ring aesthetic, with delicate gold accessories including layered necklaces and chunky rings. The cursed tape has just finished playing, the uploaded photo faintly lingering on the glowing TV screen. The twisted cord of the ringing phone catches the light, emphasizing its urgency. On the wall behind me, a flickering neon sign reads “SEVEN DAYS,” casting an ominous glow across the dark living room. The scene is styled like The Ring (2002), with VHS tapes scattered around, dark furniture, and a dim lamp diffusing a soft glow. The TV’s light reflects across my hair, while the neon sign and ringing phone amplify the chilling, cinematic realism. Highly detailed, immersive, and atmospheric, with special attention to my illuminated face, thoughtful expression, the cursed tape glow, the ringing phone, and the unsettling presence of the neon “SEVEN DAYS” warning. Do not change my face, do not change her facial features.

Como puedes ver, al final la clave está en indicar de forma muy concienzuda la foto que quieres, el estilo, las posturas y la apariencia de quienes aparecen en ella. En cuanto cojas el truco, podrás hacer lo mismo con Michael Myers, Freddy Kruger o Ghostface, por citar otros famosos villanos de HAlloween.
