車間交班，一塊空白板寫滿了沒說的話

Shoot this as an unposed documentary frame in wide 16:9 on 35mm film, 35mm lens, f/5.6: deep focus, coarse visible grain. Daylight is overcast and soft, one key from high in front, spreading evenly over everything and pooling only loosely under ledges and folds. Colour is flat and desaturated, midtone contrast honest, textures left raw. The setting is a small bus-garage workshop: concrete floor, steel workbench, pegboard of tools, green steel locker, hanging worklamp. Warm window light falls beside the wall. The outgoing mechanic is a stocky man in his late forties with tanned skin, round face, short grey beard and a little oil smudge on one cheekbone, in dark blue overalls. He holds a wooden clipboard with a blank sheet toward the incoming mechanic, a smiling heavyset Turkish man in his early fifties with olive skin, a short salt-and-pepper crew cut and a wide moustache, in a navy sweater and grey work trousers. The older man explains with his free hand held open; the newcomer leans in toward the sheet with a thoughtful frown. Beside them hangs a plain blank whiteboard with a few coloured magnet dots. Side view at eye level, framed from the waist up. Hands must have four fingers plus a thumb, exactly five digits visible or accounted for on each. Boards, tags, key fobs, clipboards, lockers and vehicles carry no readable words, numbers, logos or brand marks; they stay blank or use simple pictograms.
