ABSTRACT · ROOMS · 02 STAIRCASE — the camera climbs.

Read the rig's notes

THE ARGUMENT. Every other room moves the camera on the flat. Here seven
clearcoat treads climb away from the door, 1.5 m deep and 440 mm high
each, and one exhibit stands on every tread, left and right by turns. The
camera settles on tread one, rises to tread two, and so on, up to the
seventh; then it cranes back down to the door in five seconds, and the
whole flight stands in the frame with the lockup on the wall over the top
tread — what the climb was toward from the first frame. 60 s, no cuts. A
cream bar hangs the length of the flight, face down, so every tread
carries one rectangle of light; the nosing of every tread is a cool line.
(The lockup cannot go behind the camera: a text layer ignores a 180° yaw
and reads mirrored from the far side.)
