      "subjects": {
        "count": 2,
        "description": "the same young man and woman (early 20s), university students, ordinary and real, not model-like; faces visible and eyes sharp when visible",
        "expression": "easy smiles, wind in hair, relaxed closeness; micro-expressions only",
        "skin_and_face": "natural skin texture, no beauty retouch, no plastic skin"
      },
      "wardrobe_and_props": {
        "female": "simple casual outfit in natural tones (light top, cardigan or denim jacket), minimal makeup, long wavy hair moving with the wind",

        "props": "two bicycles (classic island style), small backpacks or tote bags"
      },
      "micro_action": "they ride side by side; one looks over and laughs; the other steadies a bag on the handlebar; a brief glance that lingers while they keep moving",
      "environment_details": {
        "location": "Büyükada island street",
        "background": "historic wooden mansions with pastel paint and weathered details, bougainvillea, tree shadows on the road, a glimpse of sea light at the end of the street, a few distant pedestrians softly out of focus",
        "ground_details": "sunlit asphalt with small cracks, scattered leaves, realistic island street texture"
      },
      "lighting": "soft sunny daylight with sky fill; controlled highlights; deep but detailed shadows under bikes and faces; subtle halation on sunlit edges",
      "composition": "eye-level moving candid shot, slightly imperfect framing like a real street photographer pa"
    }
