A realistic industrial scene showing a trained technician performing a cryogenic shrinking operation using liquid nitrogen (LN2) on a metallic bearing or bushing. The technician is wearing full safety PPE: safety helmet, transparent face shield, cryogenic insulated gloves, industrial protective clothing, and safety boots. The bearing is positioned above or inside a stainless steel Dewar container filled with liquid nitrogen, producing visible cold vapor (white fog). The work environment is a clean industrial workshop, with a stable workbench and proper layout. Lighting is realistic and neutral, high-detail textures, professional industrial photography style.
