窗边自拍的日本女性写实人像

Subject:
Represented as a selfie-style intimate smartphone portrait of only one fictional adult Japanese female, wearing a white ribbed tank top by a bright window, leaning her cheek on her left hand. The upper body is facing forward, with the face tilted slightly to the right, and the left cheek lightly resting on the left fist or bent fingers of the left hand. The center of the face is positioned at approximately 30% from the top and 49-51% horizontally on a vertical 9:16 frame, with the eye line at approximately 27% from the top. The top of the head is about 3% from the upper edge, the head width including hair is about 48% of the frame width, the shoulder width is about 67%, and the distance from the face to the upper chest is about 69% of the frame height. The right arm, right hand, waist, legs, and the smartphone itself are outside the frame and are therefore not added. Maintain a calm adult facial expression and natural body proportions, without changing to oversized eyes or an overly rounded contour to appear younger.

Face/Makeup:
The contour is an oval shape that retains the soft roundness of the cheeks, and the tip of the chin is not overly slender. Eyebrows are a natural thickness in dark brown, with a relaxed arc, not perfectly symmetrical, retaining the direction of hair growth. Eyes are slender almond shapes, with black pupils facing the lens, and the eyelid lines and eyelashes are visible to a delicate degree. Do not make the whites of the eyes bluish-white; the catchlights in both eyes correspond to the direction of the window. The bridge of the nose is soft, retaining the realism of the tip and small nostrils. Lips are a closed, elegant smile in a low-saturation pink-beige, with the corners of the mouth slightly upturned. Skin is a bright natural skin tone, retaining pores on the cheeks and around the nose, thin shadows around the eyes, and slight cheek deformation caused by contact with the left hand. Avoid strong blush, heavy eyeliner, glitter, contour-shaving processing, and porcelain-like overall smoothing.

Hair:
The hair is dark brown long hair close to black, mixing loose straight lines and faint waves, falling toward the shoulders and chest. The parting is slightly off-center to the left or right, revealing part of the forehead and forming thick bundles beside the left and right cheeks. Hair bundles facing the window retain slender bright edges, while the indoor side retains calm dark areas; do not paint the entire hair in uniform black. Near the left cheek and left hand, the hair naturally overlaps the fingers or wrist but does not embed into the skin or merge to hide fingers. Hair ends extend to the range where they are cut off at the bottom of the frame; do not create invisible lengths or back shapes. Do not use wind to blow it over a wide range; do not add wet hair, strong curls, straight bangs, exaggerated hair color gradients, or hair accessories. Retain a small amount of fine stray hairs to maintain a daily feel that is not overly tidy.

Expression/Gaze:
The gaze is quietly aimed at the lens, with a slight hint of coquettishness as if waiting for the other party's reply, creating a calm and intimate closed-lip smile. Do not open the eyes wide; naturally lower the upper eyelids so that the direction of both pupils is consistent. Because the cheek is leaning on the hand, the left cheek is slightly raised, and there is a subtle left-right difference in the corners of the mouth. Do not change to a wide laugh showing teeth, a surprised open-mouthed face, pouting lips, head down, looking sideways, or provocative half-open eyes. Do not apply force between the eyebrows or on the forehead; the corners of the eyes only bring out a very weak sense of softness. Do not completely correct the face for symmetry; retain the natural asymmetry consistent with hand contact and neck tilt. The emotion is not loneliness or sadness, but a calm atmosphere of speaking to a close-range object by a bright window.

Pose/Fingers/Contact:
The left elbow is outside the frame or at the bottom, the left forearm is bent upward, and the fingers of the left hand are slightly curled to support the left cheek. Do not clench into a fist; the contours of the thumb, index finger, and middle finger connect naturally, and only the part in contact with the cheek is slightly compressed. Correctly present the number of five fingers and joints; extra fingers, fusion, nail overgrowth, hands piercing through the cheek, and unnatural wrist twists are prohibited. Shoulders are relaxed, and the head is tilted slightly toward the hand, but do not extremely bend the neck. The right shoulder droops naturally within the visible range, and the right hand remains outside the frame. Since the smartphone holding posture is not visible in the image, it is not added. Prioritize the contact relationship between the hair, cheeks, left hand, and clothing; do not create invisible elbow positions, chairs, tables, or the lower body.

Clothing/Accessories:
The clothing is a ribbed knit tank top in a light ivory color from off-white, reproducing thin left and right shoulder straps and a shallow round chest within the visible range. Vertical fine ribs extend from the chest to the bottom edge of the frame, and the fabric is a medium-thickness matte cotton blend. The straps rest naturally on the skin, do not disappear or double mid-way, and do not pull the chest down excessively. The side illuminated by window light is bright, but do not lose the ribs due to overexposure; light gray shadows form under the armpits or under the hair. Do not add logos, text, patterns, lace, ruffles, buttons, or see-through effects. Since no clear accessories are confirmed on the neck, ears, or hands, do not create necklaces, earrings, rings, watches, or nail decorations. Bottoms or shoes outside the frame are also not shown.

Place/Time/Background:
The place suggests an interior of a daytime home or living space, but without determining the specific location or room use. There are strong bright white curtains and window light on the left side or behind the subject, and elements that look like a dark rectangular TV or monitor, light walls, and furniture parts are blurred in the background on the opposite side. The curtains are white to ivory with soft vertical folds; since specific scenery outside the window is overexposed and invisible, it is not created. Dark rectangles do not display images, text, or reflections of people. The background is more blurred than the person, retaining a sense of life while not adding cluttered items, brands, posters, plants, or others. The time period is considered soft natural light from morning to noon; do not change to sunset, night scenes, or colored lighting. Fix the front-to-back relationship between the window, the person, and the indoor background.

Composition/Camera:
A 9:16 vertical selfie-style close-up composition, including the top of the head, face, left hand, shoulders, and upper chest in one frame. The center of the face is fixed at 50% horizontally and approximately 30% from the top, and the contact point between the left hand and the cheek is placed at 35-42% horizontally and 48-55% from the top. The margin above the head is about 3%, the margins from the outside of the hair to the left and right ends are each 3-8%, and the bottom is cut off in the middle of the upper chest. The visual center of the person is maintained at 48-52% horizontally; do not squeeze the face or hair to the left or right ends. The camera is close to eye height, with a sense of distance like a smartphone standard wide-angle with an arm stretched, but without showing the actual arm or device. Avoid ultra-wide angles that distort the center of the face, flattening from long telephoto, fisheye, strong high-angle views, or tilted horizons. Focus is on the eyes, lips, and the left hand contact area, smoothly blurring the background curtains and TV.

Light Source:
The main light source is soft daylight entering from a large window on the back left or side of the frame, gently illuminating the outer edges of the hair, forehead, cheeks, nose bridge, and shoulders. Due to the backlight component, the background curtains are quite bright, but the face is adjusted to appropriate exposure using reflected light from indoor walls or the window side. Small and soft catchlights reflecting the shape of the window are placed in both eyes; do not add point-like strong flashes. The window side of the face is slightly brighter, while the opposite cheek, neck, and inner side of the hair retain soft shadows. Do not let the highlights of the white clothing and curtains overexpose; retain the gradation of visible ribs and fabric folds. Do not add warm lamps, neon, strong rim light, or multi-directional hard shadows. Unify the light direction of the hair and skin, avoiding processing where only the face glows from a separate light source.

Color/Tones:
The overall composition consists of white curtains, ivory clothing, natural bright skin, dark brown hair, an interior from light beige to gray, and a near-black TV, forming a low-saturation neutral color scheme. The white balance is slightly warm daylight, but do not excessively turn the skin yellow-orange, retaining the subtle differences in the white of the clothing and curtains. The midtones of the face are rich, smoothly connecting from the window highlights to the dark parts of the hair. The ivory of the clothing is slightly warmer than the curtains, and the dark side of the TV is kept neutral rather than bluish-black, also showing the distance between the person and the living space through color. Avoid over-brightened matte tones, blue shadows, teal and orange, strong sepia, or excessive HDR. Only naturally retain the faint blood color of the lips and cheeks, without adding primary color accents to the background. Maintain the realism of the window being slightly bright under smartphone auto-exposure, while adjusting within a range where the face does not wash out or crush to black.

Texture/Fine Details:
The skin retains small pores on the cheeks, nose, and forehead, thin shadows around the eyes, and minute longitudinal lines on the lips to a moderate degree. The contact point between the left cheek and the hand forms shape changes and small shadows under soft pressure, so the hand does not appear to be floating. The hair has strands of different thicknesses, fine waves, fine window light reflections, and a small amount of stray hairs; do not artificially sharpen individual strands. The ribbed tank top has a vertical knit pattern, soft thickness, and matte fabric with small folds at the chest and armpits. Although the curtains are more blurred than the person, vertical fabric folds are recognizable, and the TV is a dark surface with suppressed gloss. Finger skin, nails, and joints are natural; do not add overly long nails or exaggerated nail art. The overall resolution is like a smartphone photo, avoiding excessive micro-contrast or pseudo-high-frequency patterns.

Image Processing/Finish:
Completed as a natural selfie photo taken with a smartphone by an indoor window. Exposure correction only slightly suppresses the window brightness and restores the gradation of the face and white clothing. Gently adjust skin color differences, but do not eliminate pores, under-eye shadows, or cheek-hand contact. Sharpness is applied slightly to the pupils, lips, leading edge of the hair, and fingers, without adding strong outlines to the background and skin. Noise removal only suppresses the graininess around dark hair or the TV, retaining the texture of hair and ribs. The background blur is optically continuous, without creating cutout halos around the hair. Do not use beauty correction to deform the face shape, eye size, nose, mouth, or hands. Do not add text, logos, signatures, watermarks, borders, collages, dividers, or multi-cuts; complete with only one adult female and one indoor scene.

Collapse Avoidance/Prohibitions:
Fix the same adult female, dark long hair, ivory ribbed tank top, pose leaning left cheek on left hand, frontal gaze, closed smile, white curtains and dark TV, soft window light. Prohibit the increase or decrease of left hand fingers, fusion, piercing through the cheek, wrist reversal, or extra arms. Inconsistent eye directions, dual irises, melting ears or neck, disappearing shoulder straps, and hair merging with fingers are prohibited. Do not generate a smartphone, right hand, elbow position, waist, legs, or scenery outside the window based on speculation. Do not make clothing see-through, do not exaggerate the chest, and do not change to a young face. Others, mirror images, people inside the TV, text, and brands are not added to the background. Do not generate illustrations, animations, 3D, collages, grids, or comparison images; generate only a natural vertical photo of one adult female.

被摄体：
仅以一名虚构的成年日本女性为对象，在明亮的窗边穿着白色罗纹吊带背心，将脸颊倚靠在左手上的自拍式亲密智能手机肖像来再现。人物上半身正面朝向，脸部微微向右倾斜，将左脸颊轻轻搁置在左拳或弯曲的左手手指上。脸部中心置于纵向9:16画面上端约30%、横向49〜51%的位置，双眼神线置于上端约27%。头顶至上端约3%，包含头发在内的头部宽度约占画面宽度的48%，肩宽约67%，从脸部至胸上部约占画面高的69%。右臂、右手、腰部、腿部、智能手机本体位于画面外，因此不添加。保持成人的沉稳面容和自然的体型比例，不改变为显得幼小的过大眼睛或过于圆润的轮廓。

脸部・妆容：
轮廓为保留脸颊柔和圆润的卵形，下巴尖端不过分纤细。眉毛为深棕色的自然粗细，呈松弛的弧形，不完全对称，保留毛流向。眼睛为细长的杏仁形，黑瞳朝向镜头，眼睑线和睫毛呈现纤细可见的程度。不将眼白弄得青白，双目的捕捉光根据窗户方向对应。鼻梁柔和，保留鼻尖和小鼻孔的真实感。嘴唇为闭合的淡雅微笑，低饱和度的粉米色，嘴角微微上扬。皮肤为明亮的自然肤色，保留脸颊和鼻周的毛孔、眼周的薄影，以及与左手接触引起的轻微脸颊变形。避免强烈的腮红、浓重的眼线、闪粉、削减轮廓的加工，以及瓷器般的全面平滑化。

头发：
头发为接近黑色的深棕色长发，混合松散的直线和微弱的波浪，向肩部和胸部垂落。分线略微偏离中心向左或右，露出部分额头，在左右脸颊旁形成粗束。面向窗户的发束保留细长的亮边，室内侧保留沉稳的暗部，不将整体头发涂成统一的黑色。在左脸颊和左手附近，头发自然叠加于手指或手腕，但不嵌入皮肤或隐藏手指融合。发梢延伸至画面下部截断的范围，不创作不可见的长度或背面形状。不用风吹大范围飘动，不添加湿发、强烈卷曲、齐刘海、头发颜色的夸张渐变、发饰品。保留少量细碎后发丝，维持不过分整齐的日常感。

表情・视线：
视线静静对准镜头，像是等待对方回复般略带一丝撒娇，营造平静而亲密的闭唇微笑。不睁大眼睛，自然垂下上眼睑，使左右瞳孔方向一致。因脸颊倚靠手部，左侧脸颊微微上抬，嘴角也产生细微的左右差异。不改变为露出牙齿的大笑、惊讶张嘴脸、撅唇表情、低头、侧目、挑逗性的半睁眼。眉间或额头不施加力量，眼尾仅带出极弱的柔和感。不将脸部完全对称校正，保留与手部接触和颈部倾斜相符的自然不对称。情感不是孤独或悲伤，而是明亮窗边对近距离对象平静诉说的氛围。

姿势・手指・接触：
左肘位于画面外或下部，左前臂向上弯曲，左手手指轻微蜷曲支撑左脸颊。不紧握成拳，拇指、食指、中指的轮廓自然连接，仅接触脸颊的部分略微压缩。正确呈现五指数量和关节，禁止多余手指、融合、指甲增生、贯穿脸颊的手、不自然的腕部扭曲。肩膀放松，头部略微向手倾斜，但不极端折曲颈部。右肩在可见范围内自然下垂，右手保持在画面外。因智能手机持姿在图像中不可见，因此不添加。优先处理头发、脸颊、左手、服装的接触关系，不创作不可见的肘部位置、椅子、桌子、下半身。

服装・小物：
服装为从米白的浅象牙色罗纹编织吊带背心，在可见范围内再现左右细肩带和浅圆胸口。纵向细密罗纹从胸口延伸至画面下端，面料为中等厚度和哑光棉混材质。肩带自然搭于皮肤，不在中途消失或加倍，不过度拉低胸口。受窗光照射的面亮堂，但不因过曝丢失罗纹，在腋下或头发下方形成淡灰色阴影。不添加标志、文字、图案、蕾丝、褶边、纽扣、透视效果。因颈部、耳朵、手部无明确饰品确认，因此不创作项链、耳环、戒指、手表、美甲装饰。画面外的下装或鞋子也不展示。

场所・时间・背景：
场所暗示日间家居或生活空间的室内，但不断定具体位置或房间用途。画面左侧或背后有强烈明亮的白色窗帘和窗光，对侧背景有看似暗色矩形电视或显示器的元素、淡壁、家具部分模糊存在。窗帘为白色至象牙色，带有纵向柔和褶皱，因窗外具体景色白曝不可见，因此不创作。暗色矩形不显示影像、文字、反射人物。背景比人物更大程度模糊，保留生活感的同时，不添加散乱物、品牌、海报、植物、他者。时间带视为从早到午的柔和自然光，不改变为日落、夜景、彩色照明。固定窗户与人物、室内背景的前后关系。

构图・相机：
纵向9:16的自拍式近接构图，将头顶、脸部、左手、双肩、胸上部纳入一帧。脸部中心固定于横向50%、上端约30%，左手与脸颊接点置于横向35〜42%、上端约48〜55%。头顶上方余白约3%，头发外侧至左右端余白各3〜8%，下端在胸上部中途截断。人物视觉中心维持于横向48〜52%，不将脸或头发挤向左右端。相机接近眼睛高度，以智能手机标准广角拉伸手臂程度的距离感，但不显示实际手臂或设备。避免扭曲脸部中央的超广角、长望远的扁平化、鱼眼、强烈俯视、倾斜的水平线。焦点对准双目和嘴唇、左手接触部，将背景窗帘和电视平滑虚化。

光源：
主光源为画面左后方或侧方的巨大窗户射入的柔和日光，温柔照亮头发外缘、额头、脸颊、鼻梁、肩膀。因有逆光成分，背景窗帘相当明亮，但脸部以室内墙壁或窗边反射光调整至适当曝光。双目置入反映窗户形状的小而柔和捕捉光，不添加点状强闪光。脸部窗侧略亮，对侧脸颊、颈部、头发内侧保留柔和阴影。不让白色服装和窗帘的高光过曝，保留可见罗纹和布褶的阶调。不添加暖色灯、霓虹、强边缘光、多方向硬阴影。将头发和皮肤的光向统一，避免仅脸部以单独光源发光的加工。

颜色・阶调：
整体由白色窗帘、象牙色服装、自然明亮皮肤、深褐色头发、从淡米色到灰色的室内、接近黑色的电视构成低饱和度的中性配色。白平衡为略带暖意的日光，但不过分黄橙化皮肤，保留服装和窗帘白色的细微差异。脸部中间调丰富，平滑连接从窗户高光至头发暗部。服装的象牙色比窗帘略暖，电视暗面不弄成青黑而保持中性，通过颜色也显示人物与生活空间的距离。避免过分提亮的哑光调、蓝色阴影、蓝绿色与橙色、强棕褐、过度HDR。仅自然保留嘴唇和脸颊的淡血色，不向背景添加原色点缀。维持智能手机自动曝光下窗户略亮的真实感，同时调整至脸部不白曝或黑崩的范围。

材质・细微质感：
皮肤保留脸颊、鼻子、额头的细小毛孔、眼周的薄阴影、嘴唇的微细纵纹，程度适中。左脸颊与手接点形成柔和压力下的形状变化和小阴影，使手不显得浮起。头发带有粗细不同的束、细微波浪、窗光细反射、少量后发丝，不人工锐化单根发丝。罗纹吊带背心具有纵向编织纹、柔和厚度、胸口和腋下小褶皱的哑光布料。窗帘虽比人物更模糊，但可辨识纵向布褶，电视为抑制光泽的暗面。手指皮肤、指甲、关节自然，不添加过长指甲或夸张美甲。整体分辨率如智能手机照片般，避开过度微对比或伪高频图案。

图像处理・完成：
完成成室内窗边用智能手机拍摄的自然自拍照片。曝光校正仅略微抑制窗户亮度，恢复脸部和白色服装的阶调。温和调整皮肤色差，但不消除毛孔、眼下阴影、脸颊与手接触。锐度轻微施加于瞳孔、嘴唇、头发前缘、手指，不在背景和皮肤添加强轮廓线。噪点去除仅抑制暗色头发或电视周边的粗糙度，保留头发和罗纹质感。背景虚化光学连续，不在头发周遭制造抠图光晕。不以美容校正变形脸形、眼睛大小、鼻子、嘴、手。不添加文字、标志、签名、水印、边框、拼贴、分隔、多切图，仅以一名成年女性和一个室内场景完成。

崩溃回避・禁止：
固定同一成年女性、暗色长发、象牙色罗纹吊带背心、左脸颊倚靠左手姿势、正面视线、闭合微笑、白色窗帘和暗色电视、柔和窗光。禁止左手手指增减、融合、贯穿脸颊、手腕反转、多余手臂。眼球方向不一致、双重虹膜、耳朵或颈部溶解、肩带消失、头发与手指融合。不以推测生成画面外的智能手机、右手、肘部位置、腰部、腿部、窗外风景。不使服装透视，不夸张胸口，不改变为幼颜。他者、镜像、电视内人物、文字、品牌不添加至背景。不生成插图、动画、3D、拼贴、网格、比较图像，仅生成一名成年女性的自然纵向照片。
