Ritual Chamber, silver-gelatin archival film still in a near-empty East-German institute chamber, 4:5 portrait. A single black film projector rests on a hexagonal honeycomb floor beneath the room's interlocking cream-and-dark stepped-cross institute tile. Its lens projects two aligned frames onto a vast slate wall: the same door handle, the same sleeve, the same face-free figure reduced to a silhouette. Numbered callouts mark 01 CONTINUITY REEL, 02 SHOT-LIST GATE, and 03 MISSING FRAME. One phosphor-green band of small glowing film vials crosses the rear wall. A gloved hand quietly adjusts a focus ring; a domestic teacup sits beside the projector. Hard chiaroscuro, deep shadow, small mis-struck circular Bureau seal, no filing-code text. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
