16mm 黑白手持街头纪录片 prompt

Style: Vintage 16mm black-and-white documentary, high-contrast silver-gelatin grade, visible grain, slight gate weave, mild lens vignette.

A narrow market street in a working-class neighborhood, mid-morning, late autumn. Vendors set up wooden stalls; steam rises from a kettle. Pedestrians cross frame in soft motion blur. A young vendor in a wool cap arranges apples into a pyramid.

Cinematography:
- Camera: handheld ENG camera at chest height; gentle drift between subjects, no zooms
- Lens: 25mm prime; deep focus from foreground crates to background storefront
- Lighting: overcast natural sky as soft key; no fill; deep blacks in stall shadows
- Mood: observational, warm despite monochrome, lived-in

Actions:
- Vendor lifts an apple, polishes it on his apron, places it atop the pyramid
- A child runs past chasing a paper bag
- Vendor glances up at the camera, half-smiles, returns to stacking

Background Sound: Crate scrape; coins clinking; nearby radio playing a faint folk tune; footsteps on cobble. No score.
