Scan a space

  1. Camera. Best: Blackmagic Camera (free) — stabilisation Off, shutter 1/250 locked, white balance and focus locked, 1×, 4K 30, HEVC Medium. Or the Camera app: Settings › Camera › Record Video → Enhanced Stabilization off, Lock Camera on, Lock White Balance on, HDR off; hold the screen until AE/AF LOCK.
  2. Size. Print markers at 100% and lay 2–6 flat, far apart — or tape one long distance and enter it after the scan.
  3. Start and finish at the same spot, facing the same thing.
  4. Lap 1, chest height, pointed into the space. Slow steps. Lap 2, waist height, tipped down at the ground, past every marker.
  5. Turn with your feet, not your wrists. Never spin in place. Keep one big fixed thing in frame along a driveway, path or fence.
  6. 3–6 min outdoors, 1–3 indoors. Under roofs, one lap facing out. Avoid people walking through, mirrors, big glass, and long stretches of only ground.
