喧嚣都市中的电影感浅景深人像

Core Intent: 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: 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

核心意图：创作一张超浅景深、写实抓拍的街头时尚肖像，画面中一位女性在中间位置清晰对焦，周围移动的人群则呈现柔和的模糊/焦外散景效果。保留精确的构图、主体位置、色彩分级和氛围。 1) 构图与取景 (锁定) • 比例：4:5 垂直。 • 拍摄高度：胸部到眼睛水平（略高于主体肩线）。 • 取景：中景主体略偏左居中，从胸部上方到头顶清晰可见；包含肩膀；背景严重模糊。 • 前景：两个大型模糊的人形框住主体： • 左前景：模糊的中年男子占据左侧三分之一，穿着灰/蓝色夹克，面部失焦。 • 右前景：模糊的人占据右下象限（深色头发），同样失焦。 • 中右：模糊的秃顶老年男子头部/肩膀在主体右肩后方可见。 • 背景：密集的城市街道，有黄色出租车/的士形状和暖橙色焦外散景光斑；高大的城市建筑融入奶油般的模糊。 2) 主体 (主要) • 人物：年轻成年女性，白皙/浅色皮肤，细微雀斑，自然而富有时尚感的容貌。 • 头发：中棕色，凌乱的低发髻/发髻，带有松散的碎发；略带湿润/城市质感；发丝框住脸庞。 • 表情：平静，略带严肃/好奇；嘴唇放松；眼睛带着柔和、中性的强度直视镜头。 • 姿势：身体朝右（四分之三侧面），头部向左肩后方转动，看向镜头。 3) 服装与配饰 (精确感受) • 外套：米色/棕褐色 风衣（哑光棉质），领口敞开，经典翻领，略带褶皱的都市穿着质感。 • 包：小号单肩包，细金色链条肩带搭在她的右肩上；肩带略微反光；包本身大部分被遮挡。 • 首饰：可见一只小耳环（精致，暖色调）。 4) 环境 (街头氛围) • 繁忙的都市人行道/街景，人群密度高。 • 背景色调：青色/灰绿色城市薄雾 + 黄色出租车 + 暖橙色焦外散景光斑。 • 没有可辨识的标志，没有清晰的背景细节——主体后面的一切都保持奶油般的模糊。 5) 灯光 (锁定) • 自然日光，阴天到柔和的阳光（漫射），没有刺眼的阴影。 • 主体面部均匀受光，颧骨和鼻梁有柔和的高光；电影般的柔和对比度。 6) 相机与光学 (关键) • 视觉效果：长焦抓拍肖像，具有强烈的压缩感。 • 镜头：85mm–135mm 焦段，大光圈 (f/1.4–f/2.0)。 • 对焦：主体眼睛和睫毛锐利对焦；前景和背景强烈失焦。 • 景深：奶油般焦外散景，平滑过渡，边缘有轻微的猫眼焦外散景。 • 快门/感觉：背景人群因景深而自然模糊；前景人物略微暗示运动模糊。 7) 色彩科学/分级 (锁定) • 阴影和背景中带有电影般的青色/绿色调。 • 暖色高光（肤色自然，略带暖意）。 • 黄色出租车柔和地突出；橙色焦外散景光斑发光。 • 精细
