Squash any scene flat, like it went through a scanner.

• 1Shoot the scene. In the camera, tap 0.5× to fit big things like walls, floors and murals.
• 2Drag the four corners onto a flat rectangle in it: a rug, a table, floor tiles, a wall.
• 3FlatScan lays the whole scene flat onto that surface, as if seen from straight above, with no perspective.
