{
 "camera": {
  "angle": "Tight close-up from a slight low angle, looking marginally upward at the subject’s face. The frame is mostly level, not strongly canted; vertical wall lines remain near-vertical and stair edges remain mostly horizontal.",
  "height": "Camera is around the subject’s seated/crouched head height but a little below her eyeline, close enough to crop the top of hair and lower torso.",
  "lens_feel": "Moderate wide-to-normal close lens feel with very close subject distance; face is large and intimate with mild perspective expansion, while the background stairs and wall fall softly out of focus."
 },
 "empty_background_requirements": "An empty plate must preserve the same cool-lit concrete stairwell/corner: the right two-thirds should contain the vertical grey concrete wall with stains, speckling, vertical seams and mottled texture; the left third should contain the dim stair flight with horizontal step edges/risers receding upward/backward. Areas currently hidden by the woman must be filled with continuous wall and stair detail: concrete wall behind her face, hair, shoulder and coat on the right/center; the blurred steps and dark stairwell behind the hair mass on the left; and the lower foreground/background where her black clothing occupies the frame. Lighting must match the blue-grey ambient shade with a faint warm rim/highlight from upper left, and the background depth of field should remain soft so the person can be reinserted sharply in the foreground.",
 "horizon_and_depth": "No natural horizon is visible. Depth is defined by the shallow foreground portrait plane against a close concrete wall and a stairwell receding diagonally backward on the left. The right wall reads as a near vertical plane just behind the subject, while the left stairs create the main depth cue through repeated horizontal tread lines fading into blur. Background focus is soft, emphasizing the subject as the nearest object.",
 "major_surfaces": [
  "Near vertical concrete wall on the right and behind the subject, blue-grey, stained and speckled, with subtle seams and weathering.",
  "Concrete staircase on the left background, visible as stacked horizontal treads/risers receding away and upward, darker and blurrier than the wall.",
  "Dark lower foreground occupied by the subject’s black clothing; no clear floor plane is visible.",
  "Shadowed stairwell/corner space between the wall and stairs, providing a cool, dim architectural backdrop."
 ],
 "occlusion_order": "Closest to camera: loose strands of the subject’s black hair, then her face, hair mass, neck and black coat. These occlude the concrete wall across the center/right and the stairwell across the left/center. Behind her is the near concrete wall on the right/center. Farther back, the blurred stair flight occupies the left background. No other people or foreground objects intervene.",
 "subjects": [
  {
   "depth_plane": "Extreme foreground / primary portrait plane, very close to camera and only a short distance in front of the concrete wall.",
   "label": "young woman",
   "pose": "Crouched or seated low, leaning slightly back/sideways near the wall. Head tilted and turned toward screen right while eyes look upward off-screen right. Brow is tightly furrowed, eyes squinting, mouth slightly open, conveying strain or alarm. Long dark hair falls around both sides of the face, with many loose strands.",
   "screen_zone": "Dominates the center and right half of the frame. Forehead and hair reach the top edge; face spans center-right; nose and mouth sit in the right-center/lower-right; hair mass fills much of the center-left and lower center. Black shoulder/coat fills the bottom-right corner.",
   "support_contact": "Hands and feet are not visible. Lower body is cropped out. Support is implied below the frame, likely seated/crouched on a step or floor, with the back/shoulder close to or lightly against the concrete wall."
