  "title": "Viking Warrior in Polar Night  Low-Key Polarisation Study",
  "prompt": "A dark and moody black-and-white portrait of a Viking female warrior on a wind-carved, icy shoreline. She stands three-quarters to the camera, chin slightly down, eyes locked forward, hair braided under a fur-edged hood, wearing leather, chainmail, and a weathered round shield. Emphasise GENERATIVE patterns derived from optical physics: subtle grayscale interference lines and stress-fringe motifs across the shield and ice. An Iceland spar (calcite ‘sunstone’) pendant at her neck exhibits visible double-image edges (birefringence). Where her grip compresses the shield rim, render piezochromism-inspired tonal shifts as pressure bands (in monochrome). The world around her is mostly negative space—velvet blacks with just a thin rim of light tracing mail links, fur tips, and the shield’s grain. Mood: stoic, ancient, elemental.",
  "style": {
    "genre": "Low-key portrait, historical realism with generative physics overlays",
    "palette": "strict black and white (no colour), deep blacks with readable shadow detail",
    "finish": "matte, subdued highlights, honest microtexture"
  },
  "camera": {
    "focal_length_mm": 50,
    "aperture": "f/2.2",
    "iso": 200,
    "shutter_speed": "1/160",
    "exposure_comp_ev": -1.7,
    "focus": "single-point on near eye; rapid falloff into shadow"
  },
  "lighting": {
    "key": "narrow softbox at 10 o’clock, feathered past her face",
    "fill": "negative fill (black flags) on camera-right and below",
    "accent": "dim back rim at 2 o’clock catching mail and shield rim",
    "optics_emulation": {
      "linear_polarization": "cross-polarised setup (polariser on key; lens polariser at ~90°) to kill specular glare and reveal stress patterns",
      "birefringence": "enhance double-refraction edges on Iceland spar pendant and thin ice shards in foreground",
      "piezochromism": "show pressure-induced grayscale density bands where her fingers compress leather/wood"
    }
  },
  "composition": "low eye-level; three-quarter pose; warrior on left third, 70–80% of frame in shadow; faint horizon line implied, not shown",
  "environment": "arctic wind, drifting snow dust, fractured ice plates with fine interference-like banding in grayscale",
  "postprocess": "filmic S-curve with deep toe, lifted blacks just above 0 for detail, 6% organic grain, no crushed shadows, no HDR halos",
  "negative_prompt": "no colour, no neon, no fantasy glow runes, no sci-fi plastics, no gore, no modern logos or text, no over-retouching, no watermark",
