超写实街头抓拍时尚人像，带极致焦外虚化

Create a photorealistic candid street-fashion portrait with extreme shallow depth of field where a single woman is sharply in focus in the mid-ground, surrounded by a moving crowd rendered as soft blur/bokeh. Preserve the exact framing, subject placement, color grade, and atmosphere. 1) Composition & Framing (LOCK) • Aspect: 4:5 vertical. • Camera height: chest-to-eye level (slightly above the subject’s shoulder line). • Framing: mid-ground subject centered slightly left-of-center, from upper chest to top of head clearly visible; shoulders included; background heavily blurred. • Foreground: two large blurred human shapes frame the subject: • Left foreground: blurred middle-aged man occupying left third, grey/blue jacket, face out of focus. • Right foreground: blurred person occupying right-lower quadrant (dark hair), also out of focus. • Mid-right: blurred older bald man head/shoulder visible behind subject’s right shoulder. • Background: dense city street with yellow taxi/cab shapes and warm orange bokeh lights; tall urban forms dissolve into creamy blur. 2) Subject (Primary) • Person: young adult woman, fair/light skin, subtle freckles, natural editorial beauty. • Hair: medium brown, messy low updo/bun with loose wisps; slightly damp/urban texture; flyaways framing face. • Expression: calm, slightly serious/curious; lips relaxed; eyes looking directly toward camera with a soft, neutral intensity. • Pose: body facing right (3/4 profile), head turned back over left shoulder to look at camera. 3) Wardrobe & Accessories (Exact Feel) • Outerwear: {argument name="outerwear color" default="beige/tan"} trench coat (matte cotton), collar open, classic lapels, slightly rumpled city-wear texture. • Bag: small shoulder bag with thin gold chain strap on her right shoulder; strap catches a bit of light; bag itself mostly hidden. • Jewelry: small earring visible (subtle, warm tone). 4) Environment (Street Mood) • Busy metropolitan sidewalk/street scene, crowd density high. • Background palette: teal/green-grey city haze + yellow cab + warm orange bokeh lights. • No readable signage, no sharp background details—everything behind subject remains creamy blur. 5) Lighting (LOCK) • Natural daylight, overcast-to-soft sun (diffused), no harsh shadows. • Subject face evenly lit with gentle highlights on cheekbones and nose; cinematic soft contrast. 6) Camera & Optics (CRITICAL) • Look: telephoto candid portrait with strong compression. • Lens: 85mm–135mm range, wide open (f/1.4–f/2.0). • Focus: tack-sharp on subject’s eyes and eyelashes; foreground and background strongly out of focus. • Depth: creamy bokeh, smooth falloff, mild cat-eye bokeh at edges. • Shutter/feel: background crowd appears naturally blurred from DOF; slight motion blur suggested in foreground figures. 7) Color Science / Grade (LOCK) • Cinematic teal/green wash in shadows and background. • Warm highlights (skin tones natural, slightly warm). • Yellow taxi pops softly; orange bokeh lights glow. • Fine
