  "scene": {
    "environment": "A real upscale home office in the early morning, with a large window in the background and soft daylight entering from the left.",
    "desk": "Dark walnut wood with subtle scratches, small dust particles, natural grain variation and slight signs of everyday use.",

      "open cream-colored notebook with handwritten notes",
      "black metal fountain pen",

      "watch placed naturally in front of the notebook"
    ]
  },
  "watch_details": {
    "materials": "Polished stainless steel mixed with finely brushed surfaces, realistic sapphire crystal, engraved metal crown and detailed mechanical components.",
    "dial": "Dark charcoal dial with subtle vertical texture, thin applied hour markers, elegant silver hands and a small date window.",
    "movement": "The transparent caseback is partially visible and contains an intricate mechanical movement with tiny gears, screws, bridges and jeweled components.",
    "condition": "Premium but realistically used, with extremely subtle micro-scratches and fingerprints on reflective metal surfaces."
  },
  "reflection_test": {
    "crystal": "The sapphire crystal must show physically accurate reflections of the window and surrounding room while remaining transparent enough to clearly see the dial beneath it.",
    "metal": "Polished metal surfaces should reflect the environment differently from brushed metal surfaces.",
    "glasses": "The reading glasses should show subtle realistic reflections without becoming opaque.",
    "coffee": "The ceramic cup should have soft realistic highlights rather than artificial glossy CGI reflections."
  },
  "human_element": {
    "hands": "A realistic adult hand is reaching naturally into the frame to pick up the fountain pen beside the watch.",
    "anatomy": "Accurate human anatomy, natural finger positions, realistic fingernails, skin pores and subtle imperfections.",
    "interaction": "The hand must physically interact with the pen and cast a correct shadow onto the desk."
  },
  "lighting": {
    "source": "Soft natural morning window light from the left.",
    "fill": "Very subtle ambient room illumination.",
    "shadows": "Physically believable soft shadows under every object, with correct contact shadows.",
    "highlights": "Controlled realistic specular highlights on polished steel, glass and ceramic.",
    "atmosphere": "Natural photographic contrast without excessive HDR or artificial glow."
  },
  "camera": {
    "camera_type": "Professional full-frame mirrorless camera",
    "lens": "85mm macro lens",
    "aperture": "f/4",
    "focus": "Critical focus on the watch dial and front edge of the case, with gradual natural falloff toward the background.",
    "perspective": "True optical perspective with realistic proportions and no wide-angle distortion.",
    "composition": "The watch is the clear hero subject but the surrounding objects remain naturally visible and spatially coherent."
  },
  "photographic_realism": {
    "materials": "Every material must have physically distinct surface properties.",
    "imperfections": "Include subtle dust, tiny scratches, fingerprints, fabric fibers, wood grain irregularities and small environmental imperfections.",
    "depth": "Natural depth of field rather than artificial blur.",
    "color": "Neutral premium editorial photography with accurate skin tones and realistic material colors.",
    "image_character": "It should look like a photograph captured by a professional product photographer, not a 3D render."
  },
  "aspect_ratio": "3:2",
  "negative_prompt": "3D render, CGI, illustration, plastic materials, fake reflections, excessive HDR, excessive bokeh, oversaturation, perfectly clean surfaces, distorted hands, extra fingers, malformed fingers, duplicated objects, warped watch geometry, inconsistent shadows, floating objects, unrealistic depth of field, fake metal, fake glass, text, logos, watermark"
