Silver-gelatin Wet Lab production still, 4:5 portrait: on a steel tray in deep near-black, gloved hands gently hold a translucent anatomical context pouch, its cream evidence tablets entering one end and compact graphite pellets leaving the other; a thin signal-cyan valve preserves a clear original trace in sealed jars. A real hexagonal honeycomb mesh supports the tray. Numbered callouts identify 01 intake collar, 02 reversible compression membrane, and 03 retrieval valve. A chipped kitchen egg timer sits absurdly beside the specimen. Hard oblique tube-amp key, oxblood and cream with one concentrated cyan monitor band, gauze and copper, no gore, analogue warm, strong chiaroscuro. One small mis-struck circular Bureau seal. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
