日系运动场伸展女性SNS日常快照

Direction: 3:4 vertical composition realistic SNS post style smartphone photo. On a clear daytime outdoor sports field, a fictional adult Japanese female in her early to mid-20s, captured naturally by a friend with a smartphone at the moment of stretching before or after exercise. The core of the reproduction is the stretching pose with arms crossed over the head, a slender S-shaped silhouette with the body flowing to the side, light hair color, healthily tanned skin, white x pink sportswear, and a sports field composed of green, blue, and red. Established not as a cosplay shoot or advertisement shoot, but as a daily snapshot accidentally taken during actual exercise. Mood: Bright, refreshing, and healthy daytime atmosphere. The naturalness of being photographed by a friend while stretching during a break from exercise. Not a forced smile, but a friendly expression looking back at the camera for a moment. No excessively flashy, provocative, or advertisement-style treatment. Model: Fictional adult Japanese female in her early to mid-20s. Does not imitate celebrities, influencers, or real people. Natural bone structure and face shape as a Japanese person. Healthy and curvy adult female body type, no extreme anime body types or unnatural thinness. A flexible body that looks like it has an exercise habit. Face: Natural small oval face as a Japanese female. The jaw should not be too thin, and the cheeks have soft roundness. The bridge of the nose is natural and not overly prominent. Lips slightly closed, a quiet smile with only the corners of the mouth slightly raised. A natural face shape that is not perfectly symmetrical. Looking directly at the camera, but not a posing face for a shoot, but the look of suddenly turning her eyes when called out during stretching. Eyes: Natural almond-shaped eyes. Irises are dark brown to slightly bright brown. Sclera retains natural shadows. Eye makeup is elegant, with thin brown-toned lines centered on the upper eyelid and slender natural eyelashes. No flashy colored contacts, glowing pupils, or anime-style huge eyes. Hair: Long hair dyed in a light beige gold to milk tea gold. A dyed hair color that looks realistic for a Japanese female, not white like platinum, with a bit of yellowish tint. Length is slightly below the chest. Not completely straight, naturally falling in the middle with soft curls at the ends. Long bangs flow diagonally to one side, with a few strands falling by the temples and cheeks. Under the influence of the outdoor breeze and stretching movement, a few fine hairs float irregularly. Skin: Healthy Japanese female wheat skin tone as if bathed in sunlight during outdoor sports. Warm-toned golden beige, with slight color differences remaining on the face, neck, shoulders, and arms. No uniform bronze processing, retaining pores, fine hairs, thin spots, shadows around joints, etc., for a realistic photo-like subtle skin texture. No excessive beauty filters or plastic-like textures. Body: An adult female body type with a very full bust equivalent to a J-cup. However, instead of unrealistically enlarging the chest alone, the connection of shoulder width, ribcage, waist, pelvis, and thighs is established as a realistic natural human proportion. Retaining natural positions according to gravity and extremely slight left-right differences, the ribcage naturally lifts when raising the arms. A relatively slender waist, rounded pelvis, and healthy, firm legs. The protagonist of the body is not the chest, but the slender S-shaped silhouette extending from the arms to the head, ribcage, waist, and pelvis. Outfit: A regular-length white short-sleeved sports T-shirt. The crew neck and cuffs are trimmed only with light pink ribbing. No logos, text, school names, brand names, or numbers. Soft sports jersey fabric, fitting the body moderately but not completely tight. The full chest equivalent to a J-cup makes the fabric naturally pull forward, with fine pull-wrinkles extending from the side of the ribcage to the flank. When raising both arms, the fabric pulls toward the shoulders and armpits, and the regular-length hem naturally lifts slightly, with a bit of the area around the navel exposed. It is not made as a crop top from the beginning. Bottoms are light cherry blossom pink sports shorts. Soft jersey fabric, elastic waist, two thin white lines on the left and right. The length is natural, not excessively short or high-cut, naturally established as realistic sportswear. Accessories: A bright pink fabric scrunchie worn near one wrist. Not satin, but a slightly wrinkled cotton-like material. No large jewelry, flashy accessories, necklaces, or brand items. Scene_objects: Yellow-green grass field, red to dark pink running track, blue low fences or sports field equipment, followed by dark green trees. In the distance, white lines, small sports equipment, benches, sports bags, etc., can exist extremely sparingly. No huge stadiums crowded with spectators. Retain color spots on the grass, wear on the track, slight fading of the fence, etc., as small imperfections of an actually used location. Pose: Most important. The arm on the right side of the screen is stretched almost vertically upward from the shoulder, the elbow is not completely locked but slightly relaxed. The opposite arm is bent, the forearm spans behind the head, and the hand lightly touches the area from the elbow to the upper arm of the stretched arm. A natural stretching pose with both arms crossed overhead. The ribcage is slightly tilted toward the left side of the screen, and the pelvis naturally slides toward the right side of the screen. The center of gravity is slightly biased toward one leg, and the heights of the left and right shoulders and waist are not perfectly aligned. Instead of making the ribcage and pelvis face the same direction, the whole body forms a soft inverted S-shape. Not a model pose, but a natural body line formed as a result of normal stretching of the shoulders and flanks. Gravity_and_cloth: Chest, T-shirt, hair, and shorts all reflect natural gravity. The full chest equivalent to a J-cup also does not have an unnatural upward fixed shape, retaining a natural weight sensation as a human body. When raising arms, the T-shirt fabric pulls toward the shoulders, armpits, and ribcage, the chest is stretched forward, there are diagonal wrinkles on the flanks, and there is uneven lifting near the hem. The shorts also produce small fabric ripples due to the shift in gravity. Hair hangs down according to gravity, while a light breeze makes a few strands sway gently. Lighting: Clear sky to bright lightly clouded daylight. Main light is soft natural light entering from the front top-left of the screen. Natural highlights on the forehead, bridge of nose, cheeks, shoulders, upper arms, top of the T-shirt, and thighs. Natural shadows under the chin, neck, inner arms, armpits, and clothing folds. Instead of using only direct sunlight to make shadows pitch black, the blue ambient light of the sky and reflected light from the grass or ground surround weakly. For the white T-shirt part, there can be very slight overexposure as a smartphone shot. Effect: Not an advertisement photo, but a real SNS snapshot taken with a smartphone. A slight sense of JPEG compression, subtle luminance noise, and some edge processing characteristic of smartphones. There can be extremely weak motion traces just before hand shake at hair tips or fingertips. No excessive HDR, retaining slight incomplete gradations in highlights and shadows. Saturation is natural, avoiding cinematic orange-teal or strong color grading. Camera: A friend shooting with a smartphone's standard to 2x equivalent camera from a distance of about 1.8 to 2.3 meters. Natural perspective of about 50-60mm in full-frame equivalent. Camera height is at the chest to sternum level, shooting slightly upward from a position slightly lower than the subject. Not an extreme low angle. As a smartphone, no excessive shallow depth of field, the person is clear, and the background also retains information recognizable as a sports field. No artificial strong blur of portrait mode. Imperfections: Slight difference in the height of left and right shoulders. A few strands of hair are messy at the ends, and the bangs are not perfectly neat. The neckline and sleeves of the T-shirt are not perfectly symmetrical. The fabric stretch around the chest also varies slightly between left and right, with natural differences brought by posture and gravity. There are diagonal cloth folds on the abdomen or flanks produced when raising arms. Shorts also have small wrinkles or ripples. Skin is not uniformly polished, retaining subtle textures. The composition is not perfectly horizontal, with a slight tilt of about 1 degree forward or backward. Fences, grass, and tracks in the background also have small signs of use. Background: From the top of the screen, horizontal color layers of dark green trees, blue low fences, red to dark pink tracks, and yellow-green grass are formed in sequence. The person's bright hair, white T-shirt, pink trim and shorts, and healthy wheat skin stand out naturally against the green and blue of the background. No completely melting blur, retaining information to see it's an outdoor sports field. Atmosphere: Before starting light training or during a break from exercise. A scene of suddenly turning her face toward the camera without breaking the stretching pose when called by a friend while relaxing the body. Not standing perfectly from the beginning for the shoot, but a contingency captured following the flow of the scene. A daily atmosphere where the bright air of summer to early autumn, the smell of grass, or slightly dry field air can be felt. Composition: 3:4 vertical composition. A wide range from the upward-stretched arm to the upper thigh area is included. The person occupies about 75-85% of the frame. The head is near the center, the ribcage is slightly left of center, the waist is almost central, and the pelvis moves toward the right of the frame. The person's center line continues from the arms, head, ribcage, waist, and pelvis into a soft inverted S-shape. The upward-stretched arm is quite close to the top of the frame, and a part of it may be near. The left and right margins are not perfectly equal, and the right margin is slightly tighter due to the pelvis flowing to the right. Instead of just cropping or making the chest the protagonist, it's a continuous overall silhouette from the overhead arm to the thighs. Realism_priority: Top priority is that the fictional adult female as a Japanese person looks like a real photo. Instead of just emphasizing the J-cup body type specification, the bone structure, gravity, clothing tension, posture, and balance of shoulders and back are all realistic. Priority is given to posture, color composition, physical behavior of fabric, natural light, background information, and imperfections characteristic of smartphone shooting over replication of anime body proportions. Negative: Faces resembling real people or celebrities, people who look like minors, school uniforms, childish face shapes, anime faces, manga-style body proportions, bodies with unrealistically enlarged chests alone, balloon-like chests, unnatural thin waists, bodies ignoring gravity, abnormal shoulder widths, unrealistic bone structures, close-ups emphasizing only body parts, extreme low angles, excessive arched poses, gravure-style posing, bikinis, underwear, crop tops that were short from the beginning, extreme high-cuts, plastic-like skin, excessive beauty corrections, doll-like faces, excessively strong background blur, ultra-wide-angle distortion, studio lighting, overly cinematic color grading, advertisement photos, huge logos, text, UI, icons.
