Chỉ với vài thao tác đơn giản, bạn có thể biến một tấm ảnh selfie bình thường thành poster mất tích ở Hawkins, cảnh rừng Upside Down, hoặc không gian arcade neon những năm 80—tất cả đều không cần đến Photoshop.
Bộ 10 prompt chỉnh sửa ảnh bằng Gemini AI này sẽ giúp bạn tạo những bức chân dung cực chất 8K mang đậm phong cách Stranger Things: ánh sáng magenta-xanh, bào tử lơ lửng, sương mù rùng rợn, bố cục điện ảnh như poster phim, nhưng vẫn giữ nguyên gương mặt thật của bạn.
Mỗi prompt được xây dựng chi tiết để Nano Banana—công nghệ tạo ảnh của Gemini—hiểu rõ yêu cầu: giữ nguyên diện mạo, biến đổi môi trường xung quanh, xuất ảnh 8K với hiệu ứng hạt phim và chất lượng poster, tạo cảm giác như poster phim chính thức trên nền tảng streaming.
Bên cạnh đó, bài viết còn hướng dẫn quy trình thao tác nhanh, kèm những lưu ý giúp ảnh giữ được tinh thần Stranger Things: u ám, siêu nhiên, hoài cổ nhưng không bị rối mắt hoặc lạm dụng hiệu ứng kinh dị quá đà.

Mẹo & Thủ Thuật Tạo Poster Phong Cách Stranger Things
- Giữ nguyên gương mặt, chỉ thay đổi môi trường xung quanh
Luôn thêm: “do not change the face, only change environment, lighting, and outfit” vào prompt để tránh AI chỉnh sửa khuôn mặt.
- Áp dụng phong cách thị giác của phim
Tham khảo các cụm như: “80s small town,” “neon arcade,” “foggy forest at night,” “Upside Down spores,” “red-blue breach light” để tăng nét Stranger Things.
- Chốt ánh sáng kinh dị điện ảnh
Sử dụng cụm: “moody, high-contrast lighting,” “rim light from behind,” “cool blue shadows and warm red highlights,” “volumetric fog.”
- Đẩy độ phân giải và texture
Thêm: “8K, film grain, subtle chromatic aberration, light vignette” để ảnh như poster thật, không phải filter đơn giản.
- Sử dụng negative prompt mạnh
Đưa vào: “no cartoon style, no distorted faces, no extra limbs, no random text or logos” để ảnh sạch, dễ dùng.
- Chỉnh sửa như đạo diễn
Khi ảnh gần như ý, chỉ chỉnh nhẹ prompt (góc, độ mạnh sương mù, cân màu, v.v.), coi mỗi lần tạo lại như đổi góc quay phim chứ không phải viết lại toàn bộ.
10 Prompt Chỉnh Sửa Ảnh Gemini AI Phong Cách Stranger Things
Prompt 1:
“A dramatic and intense composition reminiscent of the ‘Stranger Things’ aesthetic. In the foreground, a handsome man with dark, styled hair, a beard, and piercing blue eyes looks directly at the viewer, as if taking a selfie. He is wearing a black turtleneck sweater, and a watch is visible on his left wrist. Behind him, slightly out of focus, stand several iconic ‘Stranger Things’ characters including Mike, Eleven (in her dress), Dustin (with his cap), Lucas, Max, and Steve. They are positioned in a dark, eerie environment with gnarled, shadowy vines and roots, evoking the Upside Down. The sky above is a menacing red and black, with stormy clouds, adding to the ominous atmosphere. The overall image has a slightly distorted, wide-angle or fisheye lens effect, creating a sense of being drawn into the scene. Don’t change the face, make sure the face is the same.”
Prompt 2:
“A dramatic and eerie full-body shot of a handsome man with dark, styled hair and a beard, wearing a black turtleneck and black trousers, confidently walking down a corridor. The corridor is heavily overgrown with pulsating, dark red, gnarled vines and roots, reminiscent of the ‘Upside Down’ from Stranger Things. The lighting is low and atmospheric, with a strong red glow emanating from an open doorway at the end of the corridor, through which the man appears to be emerging or towards which he is walking. The floor is dark and reflective, adding to the intense and mysterious mood. Don’t change the face, make sure the face is the same.”
Prompt 3:
“An intense, high-angle portrait of a man with dark, styled hair and a beard, looking directly upwards. He is wearing black over-ear headphones and a light blue or grey hooded jacket. His eyes are entirely white, giving him a striking and otherworldly appearance, with no visible pupils or irises. The background is a plain, textured grey surface, possibly concrete or asphalt, putting full emphasis on the subject. The lighting is even and cool-toned. Don’t change the face, make sure the face is the same.”
Prompt 4:
“A hyper-realistic cinematic selfie of a man with short dark styled hair, a groomed beard, and light eyes, wearing a tight black turtleneck sweater. He has a shocked, terrified expression with wide eyes, looking directly at the camera. He is standing in a dark, misty, blue-toned forest with twisted trees and floating ash particles, resembling the Upside Down. Looming directly behind him are two terrifying monsters: on the left, a humanoid figure with raw, red exposed muscle texture and glowing red veins; on the right, a tall creature with a fleshy, petal-like face opening to reveal rows of sharp teeth. High contrast, ominous atmosphere, 8k resolution, photorealistic textures. Don’t change the face, make sure the face is the same.”
Prompt 5:
“A captivating indoor scene reminiscent of the Byers’ living room from ‘Stranger Things’. A handsome man with dark, styled hair, a neat beard, and piercing eyes is seated on a vintage, floral-patterned sofa. He is wearing a black turtleneck sweater and black trousers, with a silver watch visible on his wrist. His hands are clasped in front of him, and he looks directly at the viewer with an intense expression. Behind him, the iconic ‘message wall’ features the alphabet hand-painted on wood paneling, illuminated by colorful Christmas lights strung above each letter. The warm, soft glow from the lights and a lamp on the left side of the frame create a cozy yet mysterious atmosphere. A rustic wooden coffee table with a small bowl and an ashtray is in the foreground, and floral patterned cushions adorn the sofa. Don’t change the face, make sure the face is the same.”
Prompt 6:
“A dramatic and otherworldly high-angle shot set in a misty graveyard. In the foreground, a man with dark hair and a beard, wearing a black turtleneck and black headphones, looks intensely upwards with completely white, pupil-less eyes, suggesting a supernatural state. He appears to be floating or positioned from a very high vantage point. Below him, two characters resembling Dustin and Lucas from ‘Stranger Things’ (one in a cap and grey hoodie, the other in a red and white varsity jacket) look up at him with expressions of fear and alarm, their hands on their heads. The ground is green grass, and several grey tombstones are visible, partially obscured by a thick, atmospheric fog that creates a spooky and mysterious mood. Don’t change the face, make sure the face is the same.”
Prompt 7:
“A vibrant and nostalgic selfie-style image featuring a handsome man with dark, styled hair, a beard, and expressive eyes, wearing a black turtleneck. He is in the foreground, looking directly at the viewer with a thoughtful pose, his hand to his chin. Behind him, a group of diverse young characters resembling the main cast of ‘Stranger Things’ (Mike, Eleven, Dustin, Lucas, Max, and Will) are smiling and posing. They are dressed in colorful, retro 1980s fashion. The background features the entrance to ‘Starcourt Mall,’ with its distinctive neon sign, and other storefronts like ‘THE GAP.’ The scene is brightly lit, evoking a warm, sunny 80s summer day. Don’t change the face, make sure the face is the same.”
Prompt 8:
“A cinematic and intense portrait of a handsome man with a well-groomed beard and styled dark hair, looking back over his shoulder with a serious, determined expression. He is holding a wooden baseball bat with large nails driven through the end, resting it against his shoulder. He is dressed in a dark jacket. The background is a dark, supernatural landscape inspired by the ‘Stranger Things’ Upside Down, featuring a massive, shadowy spider-like monster looming in a stormy, vibrant red sky filled with lightning. The environment is filled with mist, glowing blue lights in the distance, and dark, twisting tentacles in the foreground. Don’t change the face, make sure the face is the same.”
Prompt 9:
“Create a dramatic Stranger Things-inspired scene, transforming a normal photo into a hyper-realistic 8K masterpiece. The subject, a man with dark, styled hair, a beard, and piercing eyes, is standing in the foreground. He is dressed in a black turtleneck sweater, with a silver watch visible on his left wrist. The background should feature a dark, eerie environment with overgrown, pulsating red vines and roots, reminiscent of the Upside Down. Above, a menacing stormy sky with flashes of red and black clouds adds to the ominous atmosphere. The subject should appear as if he’s caught in the middle of an otherworldly, dangerous event, and the scene should have a wide-angle, fisheye lens effect for an immersive experience.”
Prompt 10:
“Create a Stranger Things-style cinematic selfie in 8K resolution, using a normal photo as the base. The subject, a man with dark hair, a beard, and intense eyes, is in the foreground. He is wearing a black turtleneck sweater, with a watch visible on his left wrist. Behind him, the scene should evoke the mysterious, eerie vibe of the Upside Down, with twisted trees, floating ash, and dark mist surrounding him. The background should include iconic elements like flickering Christmas lights, broken walls, and ominous shadows. The lighting should be soft and diffused, with flashes of red lighting coming from an unseen source, creating a supernatural atmosphere.”
