{ "portrait_prompt": { "subject": { "description": "Based on the provided reference photo, a young woman (using the face and features from the attached image) descending an elegant white marble spiral staircase, captured from BELOW at floor level looking straight up. She is mid-step, one Dior heel landing on the next stair while the other foot is still on the step above — creating a frozen moment of elegant motion. Her face from the reference photo is visible in the upper portion of the frame, looking DOWN at camera with a composed, subtly powerful expression — chin lifted, slight knowing look, as if she just noticed someone watching from below. One hand lightly trailing along the wrought-iron railing, the other hand relaxed at her side. The extreme low angle makes her appear towering and commanding.", "features": { "hair": "Hair from the reference photo falling forward slightly due to the downward gaze, framing her face, some strands catching the overhead skylight creating bright rim edges against the dark stairwell above", "eyes": "Eyes from the reference photo looking directly down at camera from above — creating a dominant gaze, powerful and composed, pupils slightly visible through falling hair strands", "expression": "Quiet authority using the facial structure from the reference photo — not smiling, not stern, just a composed awareness of being observed. The 'I see you looking' expression. Chin angled down toward camera which paradoxically makes her look more powerful due to the low angle" }, "pose": "Mid-descent on spiral staircase — dynamic walking pose frozen in time. Lead foot (right): Dior heel just touching the next marble step below, gold CD logo facing camera, largest element in foreground. Trailing foot (left): still on upper step, heel slightly lifted mid-push-off. Right hand trailing along the black wrought-iron railing with fingertips lightly touching. Left hand relaxed at side. The A-line skirt flaring outward from the descending motion, creating a circular bloom shape that echoes the spiral geometry of the staircase" }, "attire": { "type": "Cream cashmere crewneck sweater with black satin bow at right shoulder, dark satin flared A-line mini skirt, black pointed-toe Dior pumps with gold CD logo", "details": [ "Cashmere sweater: seen from below, the ribbed hem and cropped length are visible, the cream color contrasts sharply against the dark stairwell above", "Black satin bow on shoulder: catches overhead skylight, one satin tail hanging down and swaying from the motion of descending", "Satin A-line skirt: THE hero element from this angle — flared hem spreads outward like a dark bloom, the satin catches directional overhead light creating liquid highlight streaks along the flare", "Dior heels: dominate the foreground at extreme close range, gold CD logo is the sharpest detail in the frame, leather texture and stitching visible" ], "color": "Cream white + deep black, gold CD logo as foreground accent" }, "composition": { "shot_type": "Extreme low angle full body — shot from floor level at the bottom of the spiral staircase looking directly up through the spiral", "focal_length": "24mm", "aperture": "f/2.8", "camera_angle": "Extreme low angle from floor/ground level, camera pointing almost straight up, dramatic perspective convergence making everything above appear to spiral inward", "camera_height": "Floor level — camera literally on the marble floor at the base of the staircase", "framing": "3-layer vertical stack with dramatic perspective convergence. FG (bottom 1/3): Dior heel mid-step on marble stair, LARGE in frame due to wide angle proximity, gold CD logo sharp and prominent, marble step texture visible. MG (middle 1/3): flared skirt hem spreading like a dark circle, cream sweater visible above with the black bow, hands — one on railing, one at side. BG (top 1/3): the face from the reference photo looking down at camera framed by the continuing spiral of the staircase above her head like a nautilus shell, white marble + black iron railings creating concentric graphic circles, overhead skylight at the very top center as a bright circle of light", "aspect_ratio": "4:5" }, "lighting": { "type": "Single overhead skylight at the top of the spiral staircase — creating a dramatic top-down lighting gradient. Bright at the top of the spiral, progressively darker toward the camera position at the bottom", "direction": "Directly from above (skylight), creating strong top-down gradient. The marble stairs bounce and reflect the light downward, providing some fill. The wrought-iron railing casts graphic shadow patterns on the marble steps", "mood": "Dramatic architectural light — sculptural, directional, high-contrast. The skylight acts like a spotlight from heaven at the top of the spiral. Her face from the reference photo catches some of this overhead light but is partially in shadow from the angle, adding mystery. The marble reflects and glows where light hits, creating bright stepping stones upward" }, "color_palette": { "film_simulation": "ETERNA Bleach Bypass (EB)", "style": "Fujifilm ETERNA Bleach Bypass inspired color grading — high contrast, partially desaturated, the whites of the marble pushed bright and almost luminous, deep rich blacks in the skirt and iron railing with zero shadow detail, the cream sweater desaturated toward a cool white in this palette, gold CD logo retains warm metallic shimmer as the ONLY warm tone in frame, overall sculptural and architectural feel like a fashion editorial in a museum", "tones": [ "Cool bright white marble reflecting skylight", "Deep absolute black in satin skirt and wrought-iron railing", "Desaturated cream (almost silver-white) in the cashmere sweater", "Single warm accent: gold CD logo on Dior heels catching overhead light" ], "grade_notes": [ "highlight roll-off: hard, marble whites push toward blown for graphic effect", "shadow tint: neutral to cool, no warm tones in shadows", "contrast curve: high — dramatic blacks and bright whites, compressed midtones", "grain: minimal, clean and sharp to emphasize the architectural graphic quality" ] }, "environment": { "setting": "Grand white marble spiral staircase in a classical European building — museum, opera house, or luxury hotel. White Carrara marble steps, black wrought-iron railings with decorative scrollwork, overhead glass skylight at the apex of the spiral flooding the top with natural light", "background": "The spiral staircase continuing above her head — white marble and black iron creating concentric circles that draw the eye upward to the bright skylight at the center top. The geometric pattern of the spiral IS the background — no other decoration needed. Other floors/landings faintly visible through the iron railings", "atmosphere": "Monumental, architectural, the sound of heels echoing on marble in a vast quiet space. The spiral creates vertigo when viewed from below. Cold marble, warm skin — the human element from the reference photo softening the geometric perfection" }, "mood": "Architectural power — she owns this staircase. The extreme low angle transforms a simple outfit into a fashion monument. The spiral geometry frames her like a crown. NOT cute, NOT soft — this is the commanding, confident version using the person from the reference photo. She descends like she's walking a runway designed by a 19th-century architect. The single gold CD logo glinting in the foreground is the punctuation mark", "technical_tags": ["photorealistic", "extreme low angle", "wide angle perspective distortion", "architectural photography", "high contrast", "dramatic lighting gradient", "spiral geometry", "fashion editorial", "sculptural"], "negative_prompt": "flat eye-level angle, soft romantic lighting, warm cozy tones, full body standing straight on flat ground, generic hallway, low contrast, cluttered background, smiling cute expression, warm amber color grade, bokeh everywhere, candid snapshot aesthetic" } }
