"subject": {
"description": "A young adult woman sitting in a dim indoor corner, facing the camera from a slightly low and close angle. The image feels like a vintage flash snapshot with a private-room atmosphere, quiet melancholy, and a slightly underground poster-wall aesthetic.",
"mirror_rules": "Not a mirror selfie; keep it as a direct close-range seated snapshot. The camera should sit slightly below face level, with a little tilt, imperfect framing, and possible edge obstruction.",
"age": "young adult woman, early 20s",
"expression": {
"eyes": {
"look": "looking directly into the camera, calm and slightly vacant",
"energy": "low-energy, restrained, faintly tired, emotionally withheld",
"direction": "gaze slightly lowered from under the bangs toward the photographer"
},
"mouth": {
"position": "lips naturally closed with a soft lip line",
"energy": "cool, quiet, no visible smile"
},
"overall": "a still, distant expression, as if captured by flash right after she sat down quietly"
},
"face": {
"preserve_original": "Preserve the small rounded face shape, soft jawline, large eyes, thick bangs covering part of the forehead, and the realistic flash highlight across the face.",
"makeup": "A cool vintage makeup style inspired by East Asian fashion aesthetics: soft matte base, muted pink-brown eyeshadow, thin eyeliner, natural under-eye highlight, low-saturation blush, and soft rose-brown lips. Keep it slightly imperfect, with subtle smudging, darkness, and snapshot realism."
}
},
"hair": {
"color": "deep black or near black-brown",
"style": "shoulder-length bob with thick straight bangs, softly inward-curled ends, side hair close to the cheeks",
"effect": "soft but heavy silhouette in the dark, with faint cool-white flash reflections on a few strands; overall subdued by the night interior"
},
"body": {
"frame": "slim, small-framed body; the seated pose makes the silhouette feel compact and inward",
"waist": "mostly hidden under the loose cardigan, only subtly suggested by the inward posture",
"chest": "the V-neck cardigan reveals the collarbones, a small central upper-chest area, and a hint of the inner white layer; the focus should stay on the neckline shape rather than exaggeration",
"legs": "both legs bent in the foreground; one knee is raised close to the camera, the other leg folds sideways below; thighs and knees are clearly visible and softly flash-lit",
"skin": {
"visible_areas": "Visible skin includes the face, neck, collarbones, a small upper-chest area, subtle hand or wrist shadow areas, thighs, knees, and the upper edge of the lower legs. Shoulders, back, waist, hips, and buttock-adjacent areas are mostly covered and should not be additionally exposed.",
"tone": "light beige to warm ivory skin tone, appearing slightly cooler and paler under direct flash, with faint green-blue color shift in the shadows",
"texture": "realistic human skin texture: visually fine and smooth, as if it would feel soft, cool, and lightly velvety to the touch. The legs have a mild flash sheen but should never look plastic or over-smoothed.",
"lighting_effect": "direct on-camera flash hits the face, collarbones, and knee, creating local bright spots and fast-falling shadows. Highlights are slightly hard, shadows fall into dark greenish-black film grain, and edges are mildly soft."
}
},
"pose": {
"position": "sitting on the floor or a low step, body tucked into the lower center of the frame",
"base": "one leg raised near the lens, the other folded sideways; arms naturally gathered in front or hidden by long loose sleeves",
"overall": "inward, quiet, slightly guarded posture, like a close candid photo taken in a narrow room or corridor corner"
},
"clothing": {
"top": {
"type": "loose V-neck knitted cardigan with a pale camisole or tank top edge visible underneath",
"color": "light gray cardigan with an off-white inner layer",
"details": "soft fuzzy knit texture, long sleeves, relaxed neckline, slightly thick body, front buttons or a lightly closed placket",
"effect": "the fabric looks thick, warm, soft, and slightly fuzzy to the touch; the oversized fit makes the figure appear smaller and more intimate"
},
"bottom": {
"type": "short bottom mostly hidden by the cardigan, paired with black knee-high or long socks",
"color": "mostly black lower styling with dark socks",
"details": "black socks cover the lower legs, ending below the knees; the exposed leg skin contrasts strongly with the dark socks"
}
},
"accessories": {
"jewelry": "layered delicate necklaces, two thin chains with small pendants resting near the collarbones; possible tiny earrings but not visually dominant",
"device": "no visible handheld device",
"prop": "vintage posters, stickers, or magazine pages on the wall creating dense visual texture"
},
"photography": {
"camera_style": "low-light close-range flash portrait, like a compact digital camera, disposable film camera, or phone flash snapshot; keep grain, slight blur, color cast, dirt, and imperfect exposure",
"angle": "slightly below eye level, mild upward angle; the subject tilts her face downward toward the camera; the frame feels slightly tilted and compressed",
"shot_type": "close seated portrait from upper body to thighs, with knees and legs entering the foreground and the poster wall compressed behind the head",
"aspect_ratio": "vertical 2:3 or 3:4",
"texture": "high-ISO grain, old-photo haze, flash dust specks, shadow noise, slight motion blur, soft edges, dark vignette",
"lighting": "main light is direct front on-camera flash, illuminating the face, neckline, cardigan, and knee; background exposure is uneven, posters catch partial glare, while the right side and lower frame fall into deep shadow; no polished fill light or rim light",
"depth_of_field": "shallow to medium depth of field; the face is relatively clear, while legs and background are slightly soft, like an inexpensive camera autofocus result in darkness"
},
"background": {
"setting": "dim indoor room, corridor corner, or basement-like private space",
"wall_color": "dark wall covered in posters, overall blue-green, gray-black, and dark brown tones",
"elements": [
"dense vintage film or music posters",
"blurred text and image collage",
"dark vertical edge or doorframe on the right",
"dark obstruction or shadow block on the left",
"wooden or dark floor visible at the bottom"
],
"atmosphere": "narrow, humid, nocturnal, private, slightly underground, like the moment after a quiet conversation had already happened",
"lighting": "very weak ambient light, mostly dependent on camera flash; uneven background brightness, slight poster reflection, greenish-black noise in the shadows"
},
"the_vibe": {
"energy": "hushed, still, darkened, faintly rebellious yet tired",
"mood": "vintage, lonely, intimate, cool, with a night-after feeling",
"aesthetic": "East Asian / Japanese-inspired retro girl portrait, Y2K dark-room feeling, flash film snapshot, underground poster wall, non-commercial casual photography",
"authenticity": "preserve imperfections: color cast, noise, flash overexposure, crushed blacks, off-center framing, messy posters, slight missed focus",
"intimacy": "the photographer feels very close, like a familiar person taking a quiet late-night room snapshot",
"story": "She had just sat in a corner covered with old posters; the room was dark, the flash suddenly fired, and it left behind a silent, cool moment.",
"caption_energy": "like a short social caption: 'the things left unsaid that night.'"
