A photorealistic 9:16 vertical cinematic photograph inside a Japanese commuter train at night, taken candidly at eye level from across the aisle with an 85mm lens wide open at about f/1.4.
Composition: a full-body view of the subject on the left third of the frame. She occupies only about two thirds of the frame height; the upper third is filled with rows of hanging triangular hand straps and fluorescent ceiling lights receding into the distance, so the figure is never squeezed to fit the tall frame.
A young woman stands leaning against the partition next to the train door, looking down at her smartphone with calm, quiet focus. She must have realistic, natural human proportions, with a head-to-body ratio like a real person photographed at this distance. In profile she has a soft jawline, a small nose, lowered eyes and blunt bangs; her black hair is tied in a low half-up ponytail with a black hair clip. White wired earphones run from her ears. She wears a navy school blazer, a white shirt, a striped tie, a knee-length gray pleated skirt, black knee socks and black loafers, with a black leather bag on her shoulder.
Depth of field, in three layers. Foreground: the dark shoulder of a passenger in the lower right corner, completely out of focus. Midground: sharp focus on her face, hands and phone. Background: seated commuters in suits along the right and the carriage interior blurring progressively with distance, with lights turning into round bokeh. The advertisement panels are rendered only as soft, blurred color blocks with no legible text and no faces.
Muted, desaturated cool teal-gray color grading with gentle warm highlights. Quiet, slightly lonely atmosphere. Background faces unrecognizable, no text or logos.
