{ "prompt_type": "descriptive_replication", "reference_adherence": "STRICT_VISUAL_FIDELITY", "aspect_ratio": "4:5", "style": "1990s compact digital camera aesthetic with harsh on‑camera flash, grainy texture, washed‑out colors, high contrast, subtle chromatic aberration and halation. NO HDR, NO tone mapping, NO modern digital processing. The image looks like a raw, unedited flash photograph taken at the City of Arts and Sciences (Ciudad de las Artes y las Ciencias) in Valencia, Spain, during early evening (golden hour fading), using an early digital point‑and‑shoot (e.g., Kodak DC series, Sony Mavica). The flash is the main light source – it creates deep, sharp shadows and overexposed highlights, the classic 'deer‑in‑headlights' effect. Background architecture (the futuristic buildings of Santiago Calatrava) is heavily darkened but faintly visible – the white curved structures become pale silhouettes against the darkening sky. Ultra‑realistic skin texture, visible pores, natural imperfections, hair strands, fabric details – all rendered with natural grain and no smoothing. The composition is slightly tilted, with a slight vertical banding artifact (CCD readout noise), a micro‑scratch on the lens (barely visible in lower right), and a subtle vignette with a faint greenish‑purple color shift at the edges – all adding authentic 90s digital camera character. The scene is warm, lively, yet raw and candid, capturing a spontaneous moment in front of iconic Valencian architecture.", "scene": { "location": "City of Arts and Sciences, Valencia, Spain. Early evening, golden hour fading. The background features the iconic futuristic white structures designed by Santiago Calatrava: the Hemisfèric (eye-shaped building), the Museu de les Ciències Príncipe Felipe (whale‑skeleton-like museum), and the Umbracle (garden walkway). The sky is pale blue turning to warm orange near the horizon, but heavily darkened by the flash. Some other tourists are blurred in the background, out of focus. The ground is light stone or pavement, with harsh shadows.", "protagonist": "A young woman (mid‑20s), natural beauty, athletic but feminine build, sun‑kissed skin with slight tan lines. She stands facing the camera, slightly off‑center (rule of thirds), with a relaxed, joyful expression – a genuine, candid smile, eyes slightly squinting from the flash. She wears a casual summer outfit: a white linen off‑shoulder top and high‑waisted beige shorts. Her brown hair is slightly wavy, with some strands blown by a light breeze. She holds a straw hat in one hand, the other hand resting on her hip. A small crossbody leather bag is over her shoulder. Her pose is natural, not overly posed – weight on one leg, slight tilt of the head. Her skin has visible pores, tiny freckles across the nose and cheeks, and a healthy natural glow. The flash creates specular highlights on her shoulders, collarbones, and the straw hat. In the background, the Calatrava buildings rise behind her – their curved white surfaces catch faint ambient light but are mostly dark silhouettes." }, "lighting_and_atmosphere": { "source": "ON‑CAMERA FLASH ONLY (early 1990s compact digital camera).
