Light Before All Else

  "portrait_prompt": {
    "subject": {
      "description": "Based on <User Portrait>, a young East Asian woman with hair cascading down past her shoulders, sitting on a black minimalist chair, leaning forward with her upper body curved into an elegant diagonal line, head bowed down in contemplation, not looking at camera",
      "features": {
        "hair": "hair falling naturally over right shoulder, partially obscuring the face in profile, subtle warm rim light catching individual strands",
        "eyes": "Eyes downcast, looking at her own feet, eyelashes catching light in profile",
        "expression": "Serene introspection, quiet vulnerability, a private moment of stillness"
      },
      "pose": "Based on user-uploaded pose reference — seated on chair, upper body leaning forward into deep forward bend, both arms hanging down naturally, hands reaching toward or gently touching right ankle/foot, barefoot, creating a continuous diagonal line from shoulder through spine to fingertips"
    },
    "attire": {
      "type": "Based on user-uploaded clothing reference",
      "details": [
        "silver-gray metallic knit sweater — long sleeves, hemline hitting at natural waist, subtle lurex shimmer throughout the ribbed knit fabric",
        "seamless sheer nude tights — no visible waistband or reinforced toe,the nylon transitions invisibly from skin to fabric,bare toes visible through ultra-sheer material",
        "Hem falls just above knee when seated",
        "Fabric drapes naturally following body curvature"
      ],
      "color": "Silver-gray with micro-shimmer, black accented edges"

      "shot_type": "Medium-full body, capturing entire seated figure from head to feet",
      "focal_length": "85mm f/2.0",
      "aperture": "f/2.0 — shallow depth of field isolating subject from foreground and background chairs",
      "camera_angle": "Eye-level to slightly below eye-level, shooting from chest height",
      "camera_height": "Chest-level, approximately 1 meter high",
      "framing": "Diagonal composition — subject's body forms a sweeping diagonal from upper-left to lower-right; head positioned at right-third intersection; foreground: dark chair on left side creating frame-within-frame and dark mass; midground: subject at brightness transition zone; background: second dark chair on right side echoing foreground; floor light patch precisely placed at lower-right as secondary compositional anchor"
    },
    "lighting": {
      "type": "Natural window light from camera-right, soft but directional, low-key overall exposure with 60%+ of frame in shadow",
      "direction": "Right side, slightly behind subject — creating gentle side-profile illumination and subtle hair rim light",
      "mood": "A single rectangular patch of window light falling on the wooden floor at lower-right becomes the compositional anchor; subject sits at the boundary between light and shadow; hands and bare feet are precisely lit by the edge of this light patch; face in soft transitional light — neither fully lit nor in shadow"

    "color_palette": {
      "film_simulation": "ETERNA",
      "style": "Fujifilm ETERNA Cinema inspired color grading, desaturated muted tones, cinematic low-saturation palette, soft highlight roll-off, rich shadow detail without crushing blacks, warm-neutral overall with restrained color information",
      "tones": [
        "Deep warm brown wooden floor",
        "Silver-gray metallic fabric catching available light",
        "Matte black chair forms as anchoring dark shapes",
        "Warm ivory-beige wall in background"
      ],
      "grade_notes": [
        "highlight roll-off: very soft, no clipping even in floor light patch",
        "shadow tint: warm brown, NOT cool/blue — shadows feel like aged wood and warm rooms",
        "contrast curve: medium-low, lifted shadows retaining texture in dark areas",
        "grain: subtle fine grain adding tactile quality without noise"
      ]
    },
    "environment": {
      "setting": "Minimalist interior — studio, old apartment, or gallery space with lived-in character",
      "background": "Muted beige/cream wall with subtle texture, dark wooden floor with visible patina and warm tones, second black chair partially visible on right edge",
      "atmosphere": "Sparse and quiet — the emptiness of the room amplifies the intimacy of the moment; dust-mote quality to the light; still air; the kind of room where you can hear the clock tick"
    },
    "mood": "Silent introspection, sculptural grace, private vulnerability — like witnessing a dancer at rest when she thinks no one is watching",
