A silver-gelatin Ritual Chamber cinematic still, frontal but slightly low: three worn light boxes holding cropped reference details stand on deep-shadowed tiled plinths around a fourth image sheet in a black inspection cradle. A gloved hand adjusts a small phosphor-green attribute lens; a short row of green tubes is the single concentrated colour-band. The institute tile is a cream-and-dark stepped-cross pattern across the far wall; a hex lattice is physical flooring beneath the plinths. Hard cobalt key light, tube-amp warm blacks, one quietly wrong detail: a tiny domestic clothes peg grips the evidence tray. Small circular Bureau seal struck once on the inspection table. German callouts: 01 BEZUGSZEUGE, 02 MERKMAL-LINSE, 03 HARMONIESTIFT. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
