"constraints": {
"aspect_ratio": "2:3",
"medium": "DSLR digital photography, high-resolution sensor",
"shot_type": "Full body shot, seated",
"subject_instruction": "Real person from user-provided image. Identity, facial structure, and body proportions must remain exactly the same."
},
"composition": {
"framing": "Vertical, centered subject",
"camera_angle": "Eye-level, slightly low-angle perspective to emphasize the subject's presence",
"camera_distance": "Medium-full shot",
"pose": "Seated on a low concrete barrier, legs spread comfortably, hands resting in lap, relaxed shoulders",
"gaze": "Direct eye contact with the lens, neutral expression",
"crop_notes": "Full body visible from head to shoes, ample headroom and space at the bottom"

"environment": {
"location_cues": "Concrete highway divider or barrier, blurred urban bridge in background, city skyline bokeh",
"time_of_day": "Night",
"light_source": {
"type": "Artificial overhead street lighting and ambient city glow",
"direction": "Top-down and slightly from the right (subject's left)",
"softness": "Directional with soft falloff",
"falloff": "Natural light decay creating deep shadows in fabric folds and under the bridge"
}
},
"body_and_fabric_interaction": {
"posture_effects": "Hunched upper body creates compression in the torso area of the hoodie",
"fabric_drape": "Heavy puffer jacket hangs from the shoulders; hood of the inner sweatshirt rests against the neck",
"tension_zones": "Fabric of the cargo pants stretches across the knees while seated",
"compression_zones": "Pants fabric bunches heavily at the ankles where they meet the high-top sneakers",
"wrinkle_patterns": "Deep, horizontal accordion folds on the pant legs; segmented quilted puffiness on the jacket",
"gravity_behavior": "Jacket weight pulls downward, widening the silhouette; pant fabric pools around the seat and lower legs",
"contact_shadows": "Hard shadows where the body meets the concrete barrier and between fabric layers",
"fit_accuracy": "Fabric must fit the user’s real body exactly, without reshaping."
},
"materials_and_textures": {
"skin": "Visible pores, natural skin texture under night lighting, no smoothing, authentic skin tones",
"fabric": "Matte nylon jacket texture, heavy cotton jersey hoodie, rugged cotton-twill cargo pants, technical mesh and leather on sneakers",
"separation": "Sharp focus on the subject with a shallow depth of field separating them from the soft urban background bokeh"
},
"primary_focus": {
"focus_name": "Fabric-Body Night Realism",
"observable_features": [
"Quilted puffer jacket segments reacting to the seated posture",
"Cargo pant fabric bunching at the ankles due to gravity",
"High-top sneaker detail including laces and technical overlays",
"Concrete texture of the barrier showing grit and weathering"
]
},
"color_and_light_rules": {
"white_balance": "Mixed lighting; cool blue-toned background with neutral-to-warm key light on the subject",
"contrast": "High contrast between the illuminated subject and the dark night sky/under-bridge area",
"exposure": "Exposed for skin tones, maintaining detail in the black jacket while allowing shadows to remain deep",
"saturation": "Natural, muted urban palette; olive greens, deep blacks, and cool greys",
"grading_rule": "True-to-life only; no cinematic or stylized grading"
},
"camera_behavior": {
"camera_type": "35mm lens, f/2.8",
"depth_of_field": "Shallow depth of field, creamy background bokeh",
"focus_falloff": "Sharp focus on the face and torso, slight softening toward the background",
"grain_or_noise": "Subtle luminance noise consistent with high-ISO night photography",
"sharpening_limit": "No over-sharpening"
},
"overall_aesthetic": "Feels like a real, unstaged moment; documentary/editorial realism"
