Establishing reference photograph of a place: Macro photography, 3D animation style. A clean seamless grey laboratory void with even, soft, diffuse lab lighting and no visible light fixtures. Centered is a translucent anatomical mannequin bust in cutaway, chest in frame, revealing healthy pink-white lungs, a clear trachea, and a delicate bronchial tree with fine branching and alveoli. The glossy, glass-like surfaces show subtle refraction. A faint wisp of white vapor hovers at the nostrils, not yet inhaled. Shallow depth of field, crisp medical-visualization detail, calm sterile atmosphere, no text.
No people, no visible text, no watermark.
