Moody indoor environmental portrait (knee-to-head, three-quarter) of Subject[person in the image] wearing a wide black-and-ivory horizontal striped knit crewneck sweater (only 2-3 large equal stripes) and dark trousers; shot vertically at 2:3 on a full-frame digital mirrorless with a 35 mm prime from a slightly high angle (~10-15° downward tilt); settings f/2.0, ISO 800, 1/500 s, white balance Shade ~7000 K with +5 magenta tint; Kodak Portra 400 emulation plus an 81A warming filter. Composition: subject seated on the floor in the lower-right third, back against a neutral gray wall, legs bent with knees drawn up, head gently bowed, hands near lap; background is a plain wall only, with a curtain barely visible as a thin overexposed sliver at the extreme upper-left edge; large negative space above and left; rule-of-thirds with a subtle vignette. Lighting: late-afternoon golden-hour natural light from three separate windows producing three distinct tall rectangular columns of warm light on the wall, slightly offset and unequal in intensity; the lowest beam forms a narrow bright band across the subject's forehead/eyes; high-contrast chiaroscuro with crisp edges and gentle halation, flowing left-to-right. Focus: plane on the subject's face/forehead with shallow depth so the wall softens gently. Texture: pronounced film-like grain with visible dust specks and faint scratches. Color palette: warm honey/amber highlights and creamy whites against a neutral charcoal wall with black sweater stripes. Post-process: warm split-toning (highlights +15 orange, shadows +5 sepia) with a soft fade in the deepest shadows. Mood: introspective, raw, minimal, warm. Constraints: only wall and subject visible; lighting must read as three discrete rectangular window highlights; curtain barely visible; legs remain bent; no clutter or furniture; no bright saturated colors; no HOR; no extreme sharpening; no bokeh balls.
