 "camera": {
  "angle": "Very high oblique overhead / bird’s-eye establishing angle, looking down into a dense cluster of flat-roofed urban buildings. The camera is pitched steeply downward, with only vertical wall faces and roof planes visible; no sky.",
  "height": "Rooftop-to-crane height, well above the main courtyard and surrounding roofs, roughly several stories up. It looks down into multiple roof levels and narrow alleys.",
  "lens_feel": "Wide panoramic lens feel with deep focus. Strong architectural perspective and many receding diagonals, but not heavily distorted; everything from foreground parapets to distant roofs remains sharp."
 },
 "empty_background_requirements": "The empty plate must be the same high, wide overhead view of the residential rooftop complex with no people added or removed. It must preserve all architecture and props: the central walled courtyard, concrete parapets, staircases with metal railings at lower left/center, the small rooftop room with open grey door and warm-lit interior, the adjacent flat roof, laundry area with blue water tank and hanging sheets at right, stacked wooden boards and coiled material at lower right, surrounding brick-and-concrete buildings, alleys, rooftop tanks, pipes, windows, weather stains, weeds, rocks, drains, and the parked car at lower left. Since there are no visible human subjects in the still, the empty background is effectively identical to the shown image.",
 "horizon_and_depth": "No visible horizon line; depth is constructed through stacked roof planes, parapet heights, alleys, and diagonal wall edges. The image has layered depth from the foreground lower parapets and street/courtyard edge, through the central courtyard and rooftop room, to midground and background apartment roofs. Recession runs mainly from lower frame toward upper frame, with strong diagonals leading upper left and upper right through alleys and roof walls.",
 "major_surfaces": [
  "Large weathered concrete rooftop/courtyard floor occupying the central lower-middle area, mottled with stains, dirt, weeds, and scattered stones.",
  "Low concrete parapet walls forming rectangular roof enclosures across the frame.",
  "Small central rooftop structure/room with flat concrete roof, off-white stained walls, vertical windows, and an open metal door revealing a warm beige interior floor and walls.",
  "Concrete stairs and landings with silver metal railings in the lower-left to lower-center foreground.",
  "Right-side rooftop service area with pale concrete floor, blue cylindrical water tank, metal clothesline posts, hanging laundry, pipes, and vegetation along wall bases.",
  "Lower-right storage surface: stacked wooden pallets/boards with coiled rope/wire and a bicycle-like metal frame/object nearby.",
  "Surrounding red-brick and grey-concrete building façades with windows, doors, rooftop slabs, vents, pipes, and parapets.",
  "Narrow asphalt/concrete alleys between buildings, including a darker vertical lane near upper center-left and a lower street/drive area with a parked blue-grey car at bottom left.",
  "Multiple background rooftops with blue water tanks, patched concrete, tar stains, vents, corrugated metal covers, and small utility structures."
 ],
 "occlusion_order": "No people are present. Architectural occlusion proceeds from foreground parapet and stair railings at the bottom edge, then the central courtyard walls and stairs, then the central rooftop room whose walls and open door block the roof floor behind it, then the right service-yard parapet/laundry/water tank, with surrounding midground buildings and background roofs layered behind. Parapet walls repeatedly hide lower alleys and roof floors; the open door partially occludes the doorway/interior.",
