Ultra-detailed vintage noir portrait illustration generated from a reference photo, preserving exact facial identity, proportions, bone structure, and unique features (100–103% likeness fidelity). 1940s–1950s detective graphic novel style, executed in black and white engraved ink drawing. Fine cross-hatching, etching texture, and forensic sketch rendering with highly controlled line density to define facial planes and realistic shading. Strong chiaroscuro lighting with dramatic shadows and sharp highlights sculpting the face. Cinematic portrait framing (medium close-up), subject facing camera or slight 3/4 angle, maintaining natural expression from the reference. Clean, precise ink outlines combined with subtle micro-detailing (skin texture, hair strands, pores translated into engraving style). Avoid stylization distortion — maintain realism over caricature. Background composed as a retro detective dossier: technical diagrams, annotation marks, and blueprint-style elements. Incorporate halftone textures, aged paper grain, and silkscreen print imperfections. Limited color palette: primarily black and white, with selective red and warm cream accents in geometric blocks or editorial layout elements. Balanced composition with intentional white negative space. Sharp, high-resolution rendering (8k), print-ready quality, tactile analog feel. Noir atmosphere, investigative tone, archival illustration style, master-level detail. Negative prompt: distorted face, altered identity, low resemblance, cartoonish features, exaggerated proportions, blurry lines, soft edges, low detail, messy cross-hatching, over-stylization, extra facial features, deformed anatomy
