Urban fashion japanese female indoor staircase portrait

Subject:
Only reproduce a fictional adult Japanese woman as an urban fashion portrait wearing a white long-sleeved ribbed knit sweater and a gray pleated skirt, on a modern indoor staircase. The person tilts her body slightly to one side halfway up the stairs, smiling brightly at the camera positioned above. In a vertical 9:16 frame, the center of the face is located at about 27% from the top and 50% horizontally, and the line connecting the eyes is at about 25% from the top. The top of the head is about 5% from the top edge, the head width including hair is about 29% of the frame width, the shoulder width is about 50%, and the upper body and upper part of the skirt occupy about 78% of the frame height. A slender tan bag strap is visible near the left shoulder. Hands and stair handrails are almost outside the frame in this crop, so do not add them forcibly. Maintain a mature, steady facial expression and natural body proportions; do not change to a juvenile face or excessive thinness.

Face/Makeup:
The face shape is a smooth oval, with natural roundness in the cheeks and a gentle delicacy at the tip of the chin. Eyebrows are dark brown with medium thickness, in a relaxed arch, retaining the flow of hair. Eyes are slender almond-shaped, with a gaze slightly upward but directed at the camera, keeping both pupils aligned. Upper eyelid lines and eyelashes remain low-key; do not add heavy eyeliner or gaudy eyeshadow. The bridge of the nose is naturally slender, retaining the shape of the tip and nostrils. The mouth is a bright smile showing teeth, with both corners of the mouth turned up, and the lip color is a low-saturation rose beige. Skin is a bright natural tone, with a faint flush on the cheeks, thin shadows around the eyes, and slightly visible pores. Avoid strong highlights, contour-reducing processing, over-whitening, or corrections that make teeth look like a single plate. Maintain an adult freshness, and do not turn the face into a completely symmetrical CG.

Hair:
Hair is near-black dark brown straight long hair, flowing to both sides from a slightly off-center parting, falling over the shoulders and in front/behind the chest. Thick and thin strands form on both sides of the face, with one side naturally falling in front of the shoulder and the other side leaning toward the back. Extremely subtle flow due to the air on the stairs or body orientation is allowed, but do not blow excessively. Subtle gloss is shown on the top of the head and the outer side receiving window light, retaining recognizable layers of hair strands even in dark areas. Hair ends extend into the lower crop area of the frame; do not invent invisible lengths or the shape of the back of the head. Do not add wet hair, strong curls, short bangs, flashy colors, hats, or hair accessories. Hair should not penetrate shoulder straps, necklaces, or clothing, overlapping naturally in the foreground or background.

Expression/Gaze:
At the moment the face turns slightly upward to look at the camera, create a friendly and open smile showing teeth. The gaze is fixed on the lens at the top of the frame; do not change to a squint, look down, or look into the distance. The smile raises the cheeks, slightly narrows the lower eyelids, and links the corners of the mouth with the eyes. Do not change to a face with wide-eyed surprise, protruding lips, a provocative half-open gaze, or an excessively wide laugh. Teeth maintain natural size and shadows, avoiding extra teeth, melting boundaries, or excessive whiteness. Create a natural emotion like turning back halfway up the stairs to give a light greeting to an acquaintance. Do not add unnecessary tension between the eyebrows or on the forehead; retain small left-right differences in the face.

Pose/Hands/Contact:
The body is placed diagonally relative to the direction of the stairs, with one shoulder slightly forward and the neck elongated with the face upward. The upper body is nearly vertical, but creates a slight center of gravity difference as if walking or stopping. Do not shrug the shoulders; white long-sleeved arms extend naturally along the sides of the body. In the original vertical crop, contact with hands or handrails is insufficient to appear, so do not add hands near the face or force a grip on the handrail. If parts of the arms are visible at the edges of the frame, do not newly expose fingers or wrists; maintain the existing cropping method. The bag strap extends diagonally downward from the left shoulder, but do not invent the bag itself outside the frame. Do not complete invisible legs, feet, stair contact surfaces, or the back of the clothing; only naturalize the person's center of gravity.

Clothing/Accessories:
The top is a white to ivory long-sleeved ribbed knit sweater, with a V-neck that is not too deep or wide to reveal the area around the collarbones. The whole piece has slender vertical ribs, sleeves extend toward the wrists, and the body fits moderately but not vacuum-tight. Small wrinkles follow the pose at the chest, underarms, and waist; do not lose the knit texture due to overexposure. The bottom is a medium-gray pleated skirt, with vertical pleats appearing at uneven, natural intervals. A thin gold chain and a small pendant are placed on the neck, and only one tan or camel-colored thin bag strap is placed on the left shoulder. The bag body, shoes, watches, and rings are not visible, so do not add them. Logos, text, patterns, flashy decorations, see-through effects, or excessive chest exposure are prohibited.

Location/Time/Background:
The background is an indoor transparent staircase reminiscent of a high-rise building or modern commercial facility, with gray, beige, and white as the main tones. Diagonally placed stairs, horizontal or diagonal handrails, walls, and depth extending to upper floors are blurred behind the person. Do not add building names, shop names, logos, text, signs, or other people. Lighting is natural light entering from large windows above or from the side at midday; the background is bright but do not show night scenes or outdoor landscapes. When positioning, ensure stair lines do not unnaturally protrude from the person's neck or head, using the background's geometric shapes as a frame surrounding the person. Do not determine the specific location or purpose of the place; do not assume invisible settings such as stations, hotels, or offices. The background is softer and more blurred than the person, retaining only an urban sense of space.

Composition/Camera:
Vertical 9:16, using a composition centered on the upper body, placing the person in the middle from the chest up to the upper part of the skirt. The center of the face is 49-51% horizontally and about 27% from the top; the pendant is placed near 50% horizontally and about 50% from the top; the shoulder width is fixed at about 50% of the frame width. There is about 5% margin above the top of the head, and more than 9% on each side outside the hair or shoulders, with the bottom cropped mid-skirt. The person's visual center is maintained at 47-53% horizontally, with diagonal stair lines escaping to the left and right background. The camera is aimed at the vicinity of the gaze from a position slightly higher than the person, creating the feeling of the woman looking up, but avoiding extreme high-angle shots or shortened body proportions. Use a standard smartphone field of view, with clear focus on the face, hair, white knit, and pendant, and medium blurring of the stairs. Avoid fisheye, ultra-wide-angle edge distortion, telephoto flattening, or tilted vertical lines. Do not place hands or feet in unnatural positions.

Light Source:
The main light source is soft daylight entering from above or the side of the transparent stairs, illuminating from the front diagonal above the face, the shoulders of the white knit, and the outer edges of the hair. The opposite side is slightly lifted by weak reflections from walls or floors, ensuring half of the face does not turn black. Small natural catchlights are placed in both eyes; do not add hard flash spots or multi-colored light. The bright areas of the white knit are bright but do not lose the ribbing and collarline contours. Soft shadows form under the chin, on the neck, inside the hair, and in the skirt pleats, unifying the light direction. The background has slightly dark mid-tones and some bright surfaces, ensuring the face receives eye-catching exposure first. Avoid strong rim light, neon, sunset orange, or skin-only glow processing.

Color/Gradation:
Composed of a white knit, gray pleated skirt, thin tan strap, small gold pendant, dark brown hair, natural skin tone, and gray to beige architectural background. Saturation is low to medium, maintaining a neutral urban fashion atmosphere. The white clothing does not blend with the background white, creating a brightness difference for visible contours and ribbing. The gray skirt does not have strong color casts of blue or purple, with only the pendant and strap remaining as small areas of warm color. The person's skin and the white knit are not placed at the same brightness; the skin is assigned a very thin warm color, and the knit is assigned a neutral white. Faint layers are retained even in the dark areas deep in the stairs; do not turn the background into a single flat gray board. Skin does not lean toward yellow-orange; cheeks and lips retain a faint flush. Highlights, mid-tones, and shadows are smoothly connected, avoiding strong HDR, blue-green-orange, sepia tones, or crushed blacks/blown-out whites. Finished with simple colors and fresh gradations like a smartphone photo. The white and beige of the architectural background maintain a contrast one level lower than the person's clothing, ensuring the gaze does not move away from the face.

Material/Subtle Texture:
Skin retains pores on the cheeks, forehead, and around the nose, and fine lines around the eyes caused by the smile, showing them discreetly; do not plasticize. Hair has strands of different thicknesses, fine flyaways, and small glints of natural light; do not make it uniform, plate-like, or wire-like. The white ribbed knit expresses vertical knit patterns, soft thickness, and wrinkles at the shoulders and chest, avoiding satin-like strong gloss. The gray pleated skirt has light and dark between pleats and fabric drape; do not make it look like stiff paper or metal. The bag strap is a thin strap of matte leather or synthetic leather, and the pendant is only a small metallic reflection. The background walls and handrails have lower resolution than the person, guarding the depth of field of a real shot. Do not add excessive contour emphasis, fake textures, or repeating AI textures.

Image Processing/Finish:
Finish as a fashion snapshot that looks like it was taken with a smartphone in a modern indoor staircase. Lightly adjust the overall exposure, white balance, and shadows; do not brighten only the face as if it were a separate layer. Local skin correction is limited to evening out small spots; do not deform contours, eyes, nose, mouth, or dentition. Mild sharpness is applied to the pupils, corners of the mouth, front edge of the hair, knit ribbing, and pendant, with the background smoothly blurred. Slightly correct architectural line distortion, but retain the natural perspective of the camera position. Do not create cutout halos around the hair, making the background blur boundaries continuous. Do not add text, logos, signatures, watermarks, borders, collages, dividers, or multiple scenes; finish with only one adult woman and one staircase space.

Collapse Avoidance/Prohibitions:
Fix the same adult woman, dark long hair, upward smile, white ribbed knit, gray pleated skirt, small gold pendant, tan shoulder strap, indoor stairs, and soft daylight. Do not change to other clothing, characters, backgrounds, or strong colors. Prohibit eye deviation, extra teeth, melting ears, neck distortion, split shoulder straps, pendant multiplication, or hair merging with clothing. Do not speculate on showing hands, bag bodies, legs, shoes, or stair contact points outside the frame. Do not unnaturally grip the handrail, and ensure background lines do not penetrate the head or neck. Avoid see-through clothing, excessive chest emphasis, or juvenile faces. Generate only a natural vertical photo of an adult woman; no multiple people, mirroring, text, logos, collages, grids, illustrations, or 3D.
