Ritual Chamber, silver-gelatin film still, portrait 4:5: in a near-empty East-German institute chamber, a black scoring altar holds one glowing cream scorecard above seven sealed research dossiers arranged on a real hex-lattice floor. Three robed backs inspect numbered callouts: 01 RÜCKKOPPLUNGSRISS, 02 VERLEGTE SPEICHERKARTE, 03 LEERER VERSUCH. Deep cobalt shadows and hard warm key light; one short phosphor-green tube row is the only carrier accent. Institute tile on the rear wall, Bureau seal struck once at lower right, thin filing pointers, generous blank walls. One scorecard is immaculate while its dossier leaks a tiny strip of ash. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
