Subway Station Birthday Ad Selfie
GPT Image 2· Image
Create a realistic iPhone photo of the person from the reference face photo, standing in front of a Korean subway station billboard that displays the birthday advertisement from the other reference image.
=== SCENE: KOREAN SUBWAY STATION ===
A real Seoul subway station interior. The environment must include ALL of these authentic Korean subway details:
- WALLS: light grey rectangular ceramic subway tiles, clean and modern
- FLOOR: light speckled grey stone tiles with yellow tactile walking surface indicators (점자블록) running along the ground
- CEILING: plain white utilitarian ceiling with recessed rectangular fluorescent lighting fixtures, circular vent/speaker covers
- SIGNAGE: a yellow Korean subway directional sign mounted above the wall, showing exit numbers and station names in Korean and English (e.g. 논현, 반포, 고속터미널)
- BACKGROUND: the subway corridor extends into soft blur behind, with 1-2 slightly blurred passengers visible in the distance
=== THE BILLBOARD ===
- The birthday advertisement image from the reference is displayed as a large, wide, horizontal digital billboard flush-mounted on the subway tile wall.
- The billboard is internally BACKLIT — it glows softly, casting a faint warm pinkish-magenta light onto the person standing in front of it.
- The billboard surface has a matte or semi-gloss finish with minimal reflections.
- The billboard should be large enough to span roughly 2-3x the width of the person, dominating the wall behind them.
- ALL text and design elements from the birthday ad reference image must be clearly visible and legible on the billboard.
=== THE PERSON ===
- The person's FACE, facial features, skin tone, hairstyle, and overall identity must EXACTLY match the reference face photo. Do NOT alter their appearance.
- FULL BODY shot — head to shoes visible.
- POSE: standing naturally, body slightly angled toward the camera, making a V-SIGN (peace sign ✌️) with one hand raised near shoulder level. Natural, happy, genuine smile.
- OUTFIT: casual, trendy Korean street fashion — pick a random stylish outfit (examples: oversized graphic tee with wide pants, cropped cardigan with midi skirt, denim jacket with cargo pants, knit polo with jeans, hoodie with pleated skirt — choose ANY one randomly). Wearing casual sneakers or loafers. Small crossbody bag.
- POSITION: standing approximately 2-3 feet in front of the billboard, positioned slightly off-center (slightly to the right of the billboard's center). The person slightly overlaps with the edge of the billboard but the main portrait and text on the billboard remain visible behind them.
=== LIGHTING ===
- PRIMARY: cool-toned fluorescent overhead subway lighting from ceiling fixtures — creates soft, even illumination typical of underground stations.
- SECONDARY: warm, soft pinkish glow emanating from the backlit billboard, subtly illuminating the person's face and torso from behind/side.
- SHADOWS: soft shadows cast on the floor, consistent with overhead fluorescent lights.
- Color temperature: mixed — cool overhead + warm billboard glow. Realistic and natural, NOT studio-lit.
- No harsh shadows, no dramatic lighting. Everything looks natural and ambient.
=== CAMERA / PHOTO STYLE ===
- Shot on iPhone — this must look like a real candid fan photo taken on a smartphone.
- LENS: standard wide-angle mobile lens (~26mm equivalent), slight natural lens distortion at edges.
- ANGLE: straight-on, eye-level, matching the person's height.
- DEPTH OF FIELD: moderate — the person and billboard are both sharp and in focus, but the subway corridor background falls into a natural soft blur (iPhone portrait-mode-like but not extreme).
- HDR: iPhone-style high dynamic range — both the bright billboard and the darker station environment are properly exposed.
- Texture: realistic skin texture, fabric texture on clothing, tile texture on walls. No heavy retouching or airbrushing.
- Slight natural grain/noise consistent with indoor smartphone photography.
- NO filters, NO heavy color grading. Natural, true-to-life colors.
=== CRITICAL RULES ===
- The person's face identity from the reference MUST be preserved 100%.
- The birthday billboard content from the reference image MUST be accurately reproduced on the subway wall display — all text, portrait, colors, and design elements.
- Korean subway station authenticity is essential — it must look like a REAL station (Gangnam, Hongdae, Sinchon level).
- The final image must be indistinguishable from a real iPhone photo taken by a friend in a Seoul subway station.
