变形石墨素描幻觉提示

{
  "subject_core": {
    "demographics": "[STRICTLY FOLLOW REFERENCE IMAGE]: Age, gender, and ethnicity must match the uploaded source photo exactly. Rendered as a hyper-realistic graphite sketch.",
    "body_type": "Matches reference image physique, appearing to lean forward out of the 2D plane",
    "facial_features": "High-fidelity graphite translation of the reference face; shading emphasizes specific bone structure and unique traits from the source photo; eyes detailed with paper-white catchlights",
    "hair": "Matches reference image hairstyle and texture exactly, rendered with varying pencil pressure (hatching and cross-hatching)"
  },
  "subject_styling": {
    "makeup_grooming": "Matches reference image grooming standards; skin texture converted to realistic pencil grain and stippling",
    "expression": "Matches reference image expression (e.g., focused, smiling, or neutral), intense gaze directed relative to the viewer",
    "pose_action": "Anamorphic illusion: The subject's hand (drawn in graphite) creates a 3D effect, appearing to reach out of the flat paper surface, holding a realistic wooden pencil"
  },
  "wardrobe": {
    "top": "Matches clothing from reference image, textures converted to graphite cross-hatching to imply fabric weight",
    "bottom": "N/A (cropped or fading into the white of the paper)",
    "footwear": "N/A",
    "accessories": "Any distinct accessories from the reference photo rendered in sketch format"
  },
  "environment_context": {
    "location": "Macro view of a textured, heavy-tooth white sketchbook page resting on a dark rustic wooden surface",
    "background_elements": "Real-world objects resting on the paper to sell the scale: a worn white block eraser, a metal pencil sharpener, scattered cedar wood pencil shavings, smudge of graphite dust",
    "time_context": "Studio lighting environment, timeless artistic setting"
  },
  "cinematography_and_tech": {
    "lighting": "Dual lighting setup: 1. Simulated shading within the sketch based on the reference. 2. External 'real world' harsh lamp light casting long shadows from the pencil and eraser onto the paper",
    "camera_gear": "Macro photography, 100mm lens, sharp focus on the paper texture",
    "framing": "Top-down flat lay or slight isometric angle to enhance the 'pop-up' 3D illusion of the sketch",
    "visual_fidelity": "Photorealistic rendering of paper grain/fiber, tactile graphite sheen, rough charcoal texture, high contrast between dark leads and white paper",
    "color_grading": "Monochromatic greyscale for the subject (graphite/charcoal tones), natural realistic colors for the desk and drawing tools"
  },
  "aspect_ratio": "4:5"
