玻璃监工室里，经理俯视整条产线

Managerial oversight, shot low. In a 3:2 landscape crop, one manager stands inside a glass cabin up in the right-hand third; at medium portrait scale he or she fills about a quarter of the image. Below, the production floor takes up 60 to 70 percent of the height. The left third stays open, and through it rows of machinery and workers can be read in the middle distance. The camera sits low and tilts a little up at the cabin, which conveys supervision and keeps the horizon low. Cool, even illumination, soft rim separation from the overhead fixtures, and a warm amber spill on the metal surfaces for subtle contrast. Surfaces: clear glass with reflections and faint smudges on the inside, brushed steel on the machines, visible weave in the tailored jacket the manager wears. Foreground and midground carry moderate depth of field; the manager and nearest machines are sharp, background activity readable but softer. Final crop 3:2, manager held in the upper-right third, left third left empty as room for storytelling.
