Worker replacing gear in industrial portrait

A single maintenance worker is photographed as a small figure within a vast machine, positioned in the lower-left third of a 2:3 vertical frame with mechanical structures occupying the central area and extending to the upper two-thirds of the composition. The worker kneels and reaches toward one small brass gear held at center-right, the gear visibly worn with fine teeth and oily residue on its surface. Shot from a low-angle viewpoint that emphasizes the machine's scale, the framing leaves generous negative space in the right and upper-right thirds to convey monumentality. Hard-edged shafts, riveted plates and coiled hydraulic lines form layered midground elements that recede into soft industrial haze. Light is cool and directional from the upper-left, casting crisp rim light on metal edges and a warm catchlight on the worker's gloved hands. Textures are concrete matte, brushed steel, and scuffed leather on the worker's jacket with visible tool marks and faint grease sheen. Focus is moderate depth with the worker and the target gear rendered crisp while background machinery falls into a soft blur, and the overall palette balances deep steel blues with muted teal and rusted brass accents.
