Candid Park Reading Portrait

Create an authentic candid daily-life photograph in a vertical portrait frame, a medium-full shot from a low ground-level angle of {argument name="subject" default="a young Japanese woman in her early 20s"} sitting alone on lush grass in a quiet city park during an overcast afternoon. She has naturally straight, fine {argument name="hair color" default="black hair"} falling just past her shoulders with a loose center part and a few wind-displaced strands; her face is completely obscured by a centered opaque rectangular {argument name="privacy block color" default="warm brown"} privacy block. She wears a long-sleeve ribbed {argument name="top color" default="cream"} knit top with a soft scoop neckline tucked into loose wide-leg {argument name="trouser color" default="muted sage green"} trousers. Pose her seated on the lawn with one knee raised and bent to the side, one hand resting in the grass near the lower left foreground, and an open paperback book or notebook spread across her lap with visible cream pages. Use soft shade-diffused cloudy daylight, gentle cool-green color grading, natural skin and fabric texture, shallow depth of field, creamy bokeh, blurred deep green lawn behind her, a dark out-of-focus tree trunk near the upper left, and a faint pale pathway blurred in the upper right. Emphasize documentary realism, imperfect candid posture, wind-touched hair, detailed grass blades in the foreground, no studio lighting, no posing glamour, no text, no extra people.
