The Eyes That Watch Back

  "portrait_prompt": {
    "subject": {
      "description": "Based on <User Portrait>, a young woman with composed contemplative elegance, eyes lowered and nearly closed in a serene meditative expression, right arm raised gracefully behind head with elbow pointing upward opening the body line, left hand resting naturally at waist level, small delicate text tattoo visible on upper chest below collarbone, porcelain-pale skin",
      "features": {
        "hair": "hair with full blunt bangs, hair falling past shoulders in sleek sheets, catching the gallery light as the brightest element in the entire frame — functions as a natural spotlight against the dark dress and grey painting",
        "eyes": "Lowered, nearly closed — lashes visible, gaze directed downward, creating a contemplative inward-looking mood rather than engaging the camera",
        "expression": "Quiet, composed, almost reverent — red lips slightly parted, the stillness of someone standing alone with art, not performing but existing"
      },
      "pose": "Based on user-uploaded pose reference"
    },
    "attire": {
      "type": "Based on user-uploaded clothing reference",
      "details": [
        "Black satin/silk dress with liquid sheen — fabric catches soft gallery light in elongated specular highlight streaks along sleeve folds and shoulder drape",
        "Asymmetric neckline: dramatic ruffle/wave fold on left shoulder creating sculptural volume, right side more minimal",
        "Long fitted satin sleeves with visible wrinkle texture from the raised arm pose",
        "Side cutout at waist — the KEY design detail: multiple strands of delicate pearl/crystal chains criss-cross the exposed skin, connecting front and back panels",
        "Body-hugging silhouette from waist down"
      ],
      "color": "Pure black satin — the dress absorbs light everywhere except the sharp specular streaks on fold edges, creating a liquid-metal effect"
    },
    "composition": {
      "shot_type": "Medium close-up portrait, waist-up framing",
      "focal_length": "85mm f/2.0",
      "aperture": "f/2.0 — subject critically sharp, background painting readable in detail but with subtle focus falloff on edges",
      "camera_angle": "Eye-level, straight-on with minimal tilt",
      "camera_height": "Eye-level, approximately 1.5m",
      "framing": "Layered depth composition — FG: subject (sharp, dark satin dress + bright blonde hair) / BG: large oil painting fills entire background creating 'painting within photograph' meta-frame; painting's water buffalo on left third balances subject positioned on center-right; white gallery wall visible as thin strip at bottom providing breathing room; raised arm breaks the top edge of the painting frame creating visual tension between subject and artwork; adequate headroom above",
      "aspect_ratio": "1:1 square"
    },
    "lighting": {
      "type": "Gallery ambient lighting — overhead track lights diffused evenly, standard museum/gallery illumination designed to light artwork uniformly without hotspots",
      "direction": "Primarily top-down with slight front-fill from reflected gallery wall light; extremely soft and non-directional; the only visible lighting 'event' is the satin fabric's specular response — elongated bright streaks on sleeve folds and shoulder drape where the fabric angle catches the overhead source",
      "mood": "Quiet, even, respectful — gallery lighting is designed to disappear, letting the subject and artwork speak; no drama from lighting, all drama from subject/color/composition choices"
    },
    "color_palette": {
      "film_simulation": "PRO Neg Hi (NH)",
      "style": "Fujifilm PRO Neg Hi inspired color grading — professional editorial portrait tonality, rich deep blacks with preserved shadow detail in satin folds, controlled precise skin rendering trending cool-porcelain, slightly desaturated midtones but allows key accent colors (red lips, gold hair) to maintain selective vibrance, clean commercial feel with subtle film character",
      "tones": [
        "Dominant grey — painting's grey-blue-brown palette occupies 60% of frame, anchoring the muted atmosphere",
        "Deep rich black — satin dress with full tonal range from pure black to bright specular, never muddy",
        "Porcelain cool-white — skin rendered as luminous pale with minimal warmth, editorial beauty standard",
        "Platinum gold — hair as the single warm bright element, cool-gold rather than warm-gold under NH grading",
        "Precise red — lips as the ONLY saturated color in the entire frame, rendered as a deep true red, not orange-warm, functioning as a small but powerful chromatic anchor"
      ],
      "grade_notes": [
        "highlight roll-off: controlled and clean — satin specular highlights stay crisp without blooming",
        "shadow tint: neutral to slightly cool — black dress shadows show subtle cool depth, not warm",
        "contrast curve: medium-high — necessary to maintain separation between black dress and dark grey painting behind; blacks are rich and confident",
        "grain: minimal to none — commercial editorial cleanliness, every texture is fabric/skin/paint not film noise",
        "skin rendering: cool porcelain, luminous, slight desaturation — NH's specialty",
        "satin rendering: critical — the dress must show full tonal range from matte black folds to bright linear specular streaks, the liquid quality of the fabric is a key visual element"

    },
    "environment": {
      "setting": "Contemporary art gallery exhibition space — standing in front of a large-scale oil painting during what feels like a private viewing or gallery opening",
      "background": "Large contemporary Chinese oil painting in muted grey-blue-brown palette depicting a water buffalo scene with a small human figure, boats, and draped fabric/nets in an atmospheric harbor/village setting; the painting has visible impasto brushwork texture creating tactile contrast with the smooth satin dress; artist signature visible in lower right of painting (appears to be 'Guo Jun' with date); thin strip of white gallery wall below painting edge; black thin frame border barely visible",
      "atmosphere": "The quiet hum of a gallery after hours — art and fashion existing in the same frame, each elevating the other; the painting's rough textured oil strokes vs the dress's smooth liquid satin creates a tactile dialogue across mediums"
    },
    "mood": "Dark elegance, contemplative stillness, 'fashion meets fine art', the quiet confidence of someone who belongs in front of masterpieces, restrained sensuality through the pearl chain detail rather than overt display",

    "negative_prompt": "harsh flash, hard shadows on wall, overexposed highlights, shiny plastic skin, over-saturated colors, HDR look, blurry, muddy blacks losing detail, orange skin tone, warm yellow cast, visible gallery track lights in frame, distracting background visitors, cluttered composition, stiff robotic pose, eyes looking directly at camera"
