Campus Track: A Vital Close-up After Sports

9:16 vertical, realistic natural lifestyle photography, highly realistic outdoor sports portrait, combining mobile phone documentary and natural portrait texture. The main subject is a clearly adult young woman, visually aged around 22 to 25, standing by an outdoor campus sports field and red plastic track, having just finished a light run or warm-up exercise, body in a brief pause, breathing naturally, exuding an overall energetic, bright, healthy, and lively aura.

The figure is composed in a close-up environmental shot from the chest up, body slightly turned towards the camera, shoulders naturally opened backward, head slightly tilted to one side and turned towards the camera, forming a natural twist of the shoulder and neck. The figure looks up directly at the camera, corners of the mouth naturally upturned, revealing a few neat teeth, with a fresh and approachable smile, not overly radiant, not a deliberate pose.

The figure has a compact and rounded small oval face, natural and smooth facial contours, slightly full cheeks, soft and clear jawline, small but not overly sharp chin. Features are delicate and bright; eyes are clear round almond eyes, gaze is focused and real, pupils are dark brown, iris texture is naturally visible, corneal reflection comes from overcast sky light, eyes have a natural moistness, no glowing pupils. Eyebrows are natural, with real hair flow; nose bridge is delicate and smooth, nose tip is rounded and natural; lips are soft and natural, lip lines are clear, light pink lip color, makeup is light sports pseudo-bare face.

Skin has a highly realistic texture, overall healthy and delicate but not perfect, retaining small pores, fine vellus hair, slight skin tone unevenness, a few faint blushes around the forehead, nose bridge, cheeks, and alae, fine lines under the eyes, and natural sebum reflection. Skin has a slight dampness after exercise, a few small sweat beads and natural moisture reflection are visible on the forehead, cheeks, neck, collarbone, and shoulders, sweat distribution is uneven, not excessive, not forming dense water droplets, not an artificial spray texture.

The figure's black long hair is tied into a slightly loose high ponytail, with a few strands loosened after running, a few slightly damp wisps of hair clinging to the skin on the forehead and sides of the face, the ponytail naturally falls backward, hair volume and weight are realistic, not neat, no elaborate studio hairstyle. Hair edges are illuminated by soft sky light, hair layers are clear.

The figure wears a light misty blue fitted athletic tank top, simple straps, conforming to the body but not overly tight, fabric shows realistic athletic fabric texture, a few natural sweat marks are visible near the chest and neckline, color changes are slight and irregular. Clothing naturally shows the contours of the shoulders, neck, and upper body, overall healthy and athletic, not deliberately sexy.

The background is a campus or urban outdoor sports field, with a red plastic track extending in an arc behind the figure, a green soccer field or sports lawn on the right, and trees, teaching buildings, stadium light poles, and blurred buildings in the distance. The background retains real environmental information but uses natural shallow depth of field blurring. The weather is overcast or soft morning, sky light evenly illuminates the figure's face, light is soft and clean, no strong hard shadows.

Realistic photographic perspective, equivalent to around 50mm portrait focal length, close-up but not using extreme wide-angle, natural facial proportions. High-definition details, realistic pores and sweat texture, slight candid lifestyle feel, clear, clean, and natural image.

Negative constraints: influencer face, cosmetic surgery template face, childish underage feel, V-shaped face, exaggerated pointed chin, exaggerated large eyes, glowing pupils, overly heavy false eyelashes, heavy makeup, fake smile, stiff expression, perfectly symmetrical face, plastic skin, ceramic skin, wax skin, excessive airbrushing, disappearance of skin texture, excessive sweat beads, artificial water spray effect, excessive oiliness, excessive HDR, excessive sharpening, extreme wide-angle, magnified nose, wig feel, plastic feel of clothing, excessive background blur, deformed track, distorted body, incorrect shoulder and neck structure, subtitles, logos, watermarks.

9:16 豎版,寫實自然生活攝影,高度真實的戶外運動人像,手機紀實與自然人像質感結合。畫面主體是一位明確成年的年輕女性,視覺年齡約 22 至 25 歲,站在校園戶外運動場與紅色塑膠跑道邊,剛結束一段輕微跑步或熱身運動,身體處於短暫停頓狀態,呼吸感自然,整體氣質元氣、明亮、健康、輕快。

人物採用胸部以上環境近景構圖,身體輕微側向鏡頭,肩部自然向後打開,頭部向一側輕微傾斜並轉向鏡頭,形成自然的肩頸扭轉關係。人物抬眼直視鏡頭,嘴角自然上揚,露出少量整齊牙齒,笑容清爽、有親近感,不過度燦爛,不是刻意擺拍。

人物擁有緊湊圓潤的小鵝蛋臉,面部輪廓自然流暢,臉頰輕微飽滿,下頜線柔和清晰,下巴小巧但不過分尖銳。五官清秀明亮;眼睛為清澈圓杏眼,眼神聚焦真實,瞳孔深棕色,虹膜紋理自然可見,角膜反射來自陰天天空光,眼睛有自然濕潤感,不做發光瞳孔。眉毛自然,有真實毛流;鼻樑清秀流暢,鼻頭圓潤自然;嘴唇柔軟自然,唇紋清晰,淡粉色唇色,妝容為輕薄運動偽素顏。

皮膚為高度真實質感,整體健康細膩但不完美,保留額頭、鼻樑、臉頰和鼻翼周圍的細小毛孔、細微絨毛、輕微膚色不均、少量淡淡泛紅、眼下細紋與自然皮脂反光。運動後皮膚帶輕微潮濕感,額頭、臉頰、脖頸、鎖骨與肩膀可見少量細小汗珠與自然水分反光,汗水分布不均勻,不過量,不形成密集水珠,不做人工噴霧質感。

人物黑色長髮紮成略微鬆散的高馬尾,跑動後髮絲有少量鬆動,額前與臉側有幾縷微濕碎髮貼近皮膚,馬尾自然向後垂落,髮絲蓬鬆度和重量感真實,不整齊,不使用精緻棚拍髮型。頭髮邊緣受柔和天空光照亮,髮絲層次清晰。

人物穿淺霧藍色修身運動背心,肩帶簡潔,貼合身體但不過度緊繃,面料呈真實運動布料紋理,胸口和領口附近有少量運動後的自然汗濕痕跡,顏色變化輕微且不規則。服裝自然表現肩頸與上半身輪廓,整體健康運動感,不刻意性感。

背景為校園或城市戶外運動場,紅色塑膠跑道從人物身後弧形延伸,右側為綠色足球場或運動草坪,遠處有樹木、教學樓、體育場燈柱與模糊建築。背景保留真實環境資訊,但採用自然淺景深虛化。天氣為陰天或柔和清晨,天空光均勻照亮人物臉部,光線柔和乾淨,沒有強烈硬陰影。

真實攝影透視,等效 50mm 左右人像焦段,近距離但不使用極端廣角,人物面部比例自然。高清細節,真實毛孔與汗液質感,輕微生活抓拍感,畫面清透、乾淨、自然。

負面約束:網紅臉,醫美模板臉,幼態未成年感,錐子臉,誇張尖下巴,誇張大眼,發光瞳孔,假睫毛過重,濃妝,假笑,僵硬表情,完全對稱臉,塑膠皮,陶瓷皮,蠟像皮,過度磨皮,皮膚紋理消失,汗珠過多,人工噴水效果,油光過重,HDR 過強,過度銳化,極端廣角,鼻子放大,假髮感,服裝塑膠感,背景過度虛化,跑道變形,身體扭曲,肩頸結構錯誤,字幕,標誌,浮水印。
