A lateral tracking shot glides past a row of industrial presses in a cavernous steel mill. A welder's arc erupts in the mid-ground, throwing hard blue-white light and a shower of sparks that arc and die on the concrete floor. Overhead sodium lamps cut hazy orange cones through smoke. Silhouetted workers cross the frame in the foreground. High-contrast mixed color temperature, heavy atmospheric particulate, gritty texture, slow-motion spark trails, hard industrial realism.
