Street Bokeh Fashion Portrait

Create an ultra-shallow depth-of-field, realistic street fashion snapshot portrait featuring a woman in the middle of the frame in clear focus, while the surrounding crowds appear soft blur and out-of-focus blur. Preserve precise composition, subject placement, color grading, and atmosphere. 1) Composition and Framing (Locked) • Aspect ratio: 4:5 vertical. • Camera height: chest to eye level (slightly above the main body's shoulder line). • Framing: The center frame is slightly centered to the left, clearly visible from above the chest to the top of the head; Includes shoulders; The background is severely blurred. • Foreground: Two large, blurry humanoid figures frame the subject; • Left foreground: A blurred middle-aged man occupies the left third of the frame, wearing a gray/blue jacket, with an unfocused face. • Right foreground: blurry people occupy the lower right quadrant (dark hair), also out of focus. • Middle right: The head or shoulders of a blurry balding elderly man are visible behind the subject's right shoulder. • Background: dense city streets with yellow taxi shapes and warm orange focused blurred light spots; Tall city buildings blend into creamy blur. 2) Main Subjects • Characters: Young adult women with fair/light skin, fine freckles, naturally aesthetically pleasing. • Hair: medium brown, messy low bun/updo with loose strands; Slightly damp/urban texture; Hair frames the face. • Expression: calm, slightly serious/curious; Lips relaxed; Her eyes look directly into the lens, carrying a soft, neutral intensity. • Posture: Body facing right (three-quarters side), head turned to left shoulder to look at the camera. 3) Clothing and accessories (precise feel) • Jacket: beige/tan trench coat (matte cotton), open collar, classic lapel, slightly pleated urban feel. • Bag: A small shoulder bag with a fine gold chain shoulder strap, hanging on her right shoulder; The straps catch some light; Most of the bag itself is hidden. • Jewelry: visible small earrings (delicate, warm tones). 4) Environment (Street Atmosphere) • Busy urban sidewalks/street scenes with high crowd density. • Background tones: cyan/gray-green city fog + yellow taxi + warm orange out-of-focus blur light spots. • No readable signage, no clear background details—everything behind the subject remains creamy blur. 5) Lighting (Locked) • Natural daylight, cloudy to soft sunlight (diffuse), without harsh shadows. • The main face receives even light, with soft highlights on the cheekbones and bridge of the nose; Cinematic soft contrasts. 6) Photography and Optics (Critical) • Effect: Telephoto snapshot with a strong sense of compression. • Lens: 85mm–135mm focal length, large aperture (f/1.4–f/2.0). • Focus: Sharp focus on the subject's eyes and eyelashes; The foreground and background are strongly out of focus. • Depth of field: creamy out-of-focus blur, smooth transition with slight peephole-like blur at the edges. • Shutter/Feel: Background crowds naturally blur due to depth of field; The foreground figures suggest slight movement blur. 7) Color Science/Grading (Locked) • Cinematic cyan or green tones in shadows and backgrounds. • Warm highlighter (natural skin tone, slightly warm). • Yellow taxis gently pop out; Orange focal out-of-focus blur light spots glow. • Meticulous
