An ink illustration scene, ta86_lightlab, showing an adult man with short black hair, a sharp angular face and dark eyes. He is wearing a simple dark coat rendered in bold ink strokes. The lighting is expressed through high contrast between solid black ink areas and untouched paper, using negative space as light. Highlights are represented by clean white paper shapes, while shadows are dense and opaque. The light feels graphic, deliberate and abstract, defined entirely by composition and contrast rather than gradients. The scene demonstrates how ink based lighting relies on shape, edge and negative space to convey illumination. The background is raw paper texture with minimal detail. <lora:ZIT_ta86_dark_spectrum_v1_10:0.5>
