穿白色大码T恤在明亮室内前倾的日本女性

Subject:
A fictional adult Japanese female alone, wearing a white oversized T-shirt in a bright living space, reproduced as an intimate and natural smartphone photo. The person stands in the center of the frame, the upper body slightly bent forward from the waist and leaning closer, hands extended downwards, placing the left and right hands near the respective knees on the same side. Shown down to near the bottom below the knees, but the tips of the toes are out of the frame. Do not add people other than the subject, mirrors, photos, or characters in posters.

Location · Time · Background:
The background is a realistic interior where daylight enters, with light-colored walls, windows or curtains, and elements around low furniture or beds visible but blurred behind the person. The protagonist of the scene is the person; do not place specific items that could determine furniture brands, room use, or building location. The background is mainly in bright neutral tones, unified with white, beige, light gray, and low-saturation wood colors. Natural light entering from the window on the left rear or behind should be felt; do not change to night views, sunsets, or outdoor scenery.

Clothing · Small items:
The clothing features a solid-colored white oversized short-sleeved T-shirt as the protagonist. The neckline is a shallow crew neck that fits the neck naturally, the sleeves loosely cover the upper arms, and the torso part hangs loosely to the waist and above the hips. As she leans forward, soft vertical folds are created from the chest to the abdomen, and diagonal folds are created from the armpits to the hem, without letting the fabric cling tightly to the body in a vacuum. The white is not a single pure white but retains highlights on the window side, mid-tones in the center of the torso, and light gray shadows at the armpits or hem. Do not generate small items like necklaces, watches, rings, or bags that cannot be confirmed in the original image.

Pose · Fingers · Contact:
Lean the upper body forward from the waist, bringing the head and shoulders closer to the camera, with the back not excessively hunched, forming a soft forward-leaning line. Knees are slightly bent, legs naturally spaced apart, and the center of gravity is placed slightly forward in the middle. Shoulders are not shrugged, sinking gently on both sides, and the neck is not excessively elongated. The right hand touches above the right knee, and the left hand touches above the left knee; the palms are not fully displayed, and fingers naturally spread and fit the curved surface of the knees.

Expression · Gaze:
Look directly at the camera, making eye contact kindly, with a bright and defenseless smile as if the body is leaning in to welcome a visitor. The degree of opening of the left and right eyes is unified within a natural range, retaining the slight upward lift of the lower eyelids and the roundness of the cheeks brought by the smile. The expression is not a fake smile for advertisements but a moment of naturally smiling back at the other person at a close distance indoors. Do not apply force between the eyebrows; the expression around the forehead or nose remains gentle. Do not turn the gaze to the side, look down, make a surprised face, use provocative half-open eyes, or open the mouth excessively.

Face · Makeup:
The face shape is a soft inverted triangle to oval outline, the forehead is not excessively covered by bangs, and the cheeks naturally lift with the smile. Eyebrows are a soft dark brown arch that is not too thin, eyes are wide, and the pupils are aimed toward the camera. The mouth is a bright smile showing teeth, the upper lip is thinner, the lower lip is slightly fuller, and both sides of the corners of the mouth are upturned. The base makeup is thin and even, the cheeks have a very faint flush, and the lips are low-saturation pink-beige. The lines of the upper eyelids and eyelashes remain visible as in a photograph; do not add strong eyeliner, unnatural edges of colored contact lenses, or extreme eyeshadow.

Hair:
Hair is dark brown close to black, natural straight hair falling below the shoulders, on the longer side. A parting slightly offset from the center creates bangs and side strands, following along the left and right cheeks or the outside of the shoulders. Do not let the hair outline blend excessively into the background, do not depict it strand by strand like wire, and the volume and length on both sides of the face are fixed within the range of the original image. Following gravity as the upper body leans forward, the ends of the hair are divided into two sides falling in front of the chest and on the back, not made into a uniform curtain shape frozen in mid-air.

Light Source:
The main light source is soft daylight entering from a window, illuminating from the front diagonal above the face, placing small reflections in the eyes. The forehead, cheeks, tip of the nose, and white T-shirt have brightness but do not lose outlines or fabric folds due to overexposure. Create soft shadows under the chin, neck, armpits, and around the knees, with the shadow direction unified. The window side of the background is slightly brighter than the person to maintain a daylight feel, but through natural exposure correction, avoid the person's face becoming dark due to backlighting. Fill light is limited to weak reflections from white walls or floors; do not add hard shadows from studio flashes, colored lighting, or strong rim highlights.

Color · Tone:
Overall tone is based on the white T-shirt and bright interior, combined with warm skin tones, dark brown hair, and beige to gray background to form a low-saturation natural color. The white balance is slightly warm daylight; do not let the skin lean toward yellow-orange, and do not let the white clothing be stained with blue or green. Transitions from highlights to mid-tones are smooth, keeping the three-dimensionality of the face, the folds of the T-shirt, and the luster of the hair within a simultaneously recognizable range. With a smartphone-like straightforward tone, simultaneously make the bright parts of the face smooth and leave the dark parts of the interior slightly soft.

Material · Subtle Texture:
The background walls, fabric, and wooden elements have a lower resolution than the person, following the depth of field of an actual shot. Details match the natural sense of resolution of a smartphone capture; do not add excessive outline emphasis, fake high-frequency noise, or AI-specific fine patterns. On the skin, appropriately retain small pores on the cheeks, forehead, and around the nose, fine lines at the corners of the eyes, and vertical lines on the lips, not making it into a uniform plastic surface.

Composition · Camera:
A vertical 9:16 frame. The visual center of the person is 49-51% horizontally, and the center of the face is also 48-52% horizontally. The top margin of the head is about 7%, and the narrowest left and right margins from the hair or shoulders are more than 10% each. The center of the face is about 27% from the top of the frame and near 50% in the center horizontally; the line connecting both eyes is fixed at about 25% from the top. The top margin from the head to the upper edge is about 7%, the head width including hair is about 24% of the frame width, the shoulder width is about 43%, and the maximum width of the torso including the white T-shirt is about 61%. The camera position is near the height of the woman's chest to shoulders, fixing the leaning face in the upper center, the white T-shirt torso in the center, and the flow of both knees and hands at the bottom. The camera is almost horizontal but retains a slight perspective that expresses the sense of distance of the person approaching. The background is moderately blurred, while the face, front edges of the hair, T-shirt, both hands, and knees maintain a recognizable resolution.

Image Processing · Finishing:
The finishing prioritizes looking like a single photo taken indoors with the latest smartphone. Lens correction is generally natural, maintaining vertical lines while retaining the slight perspective of close-up shooting. Denoise to the extent that the texture of hair or fabric does not vanish, and sharpness is slightly applied to the eyes, mouth, and T-shirt outlines. Background blur has optical continuity, not creating cut-out white edges or halos around the person. Do not excessively unify the local flush or shadows of skin color; even if used for advertising, it retains the temperature of everyday life. Local correction for face detection remains weak, with overall adjustments to exposure, color temperature, shadows, and highlights, not just making the skin smooth like a separate layer.

Collapse Avoidance · Prohibitions:
Fix the same face, hair, white T-shirt, leaning pose, contact between hands and knees, indoor configuration, daylight, and low-saturation finish; do not replace with other clothing, other people, or other locations. Do not excessively eliminate the left-right asymmetry of the face; forbid differences in eyeball direction, ghosting irises, distorted teeth, melted ears, or twisted necks. Both hands must be naturally connected to each knee, not creating finger additions/omissions, merging, joint reversal, or wrist truncation. Avoid T-shirt logos, transparency, excessive chest emphasis, or blending of clothing and skin. Do not speculatively generate toe tips, shoes, the back, room panoramas, or personal belongings outside the frame. Do not place other people, mirrors, or people in photos, or readable text in the background. Do not make into a collage, grid, before-and-after comparison, multiple scenes, multiple people, illustrations, 3D renders, or excessive beauty retouching; conclude as a natural vertical photo of a single adult woman.

被摄主体：
以虚构的成年日本女性单独一人，在明亮的生活空间中穿着白色超大号T恤的样子，拍摄成亲密而自然的智能手机照片来再现。人物站在画面中央，上身从腰部向前微微弯折靠近，双手向下伸展，将左右手分别放在同侧膝盖附近。膝盖以下显示到下端附近，但脚尖在画面外，不添加人物以外的人、镜像、照片、海报内的角色。

地点・时间・背景：
背景是白天光线进入的具有真实感的室内，人物背后有淡色的墙壁、窗户或窗帘、低矮家具或床铺周边的元素模糊可见。场地的主角是人物，不放置能断定家具品牌、房间用途、建筑物位置的特定物品。背景以明亮的neutral色调为主，以白色、米色、淡灰色、木质低饱和色来统一。从左后方或背后的窗户进入的自然光要能感受到，不改为夜景、日落、户外风景。

服装・小物件：
服装以纯色的白色超大号短袖T恤为主角。领口是浅圆领，自然贴合颈部，袖子宽松覆盖上臂，身躯部分宽裕地垂落到腰部和臀部上方。随着前倾，在胸口到腹部产生纵向柔和的褶皱，从腋下到下摆产生斜向褶皱，不让布料真空紧贴身体。白色不是纯白一色，而是保留窗户一侧的亮面、躯干中央的中调、腋下或下摆的淡灰色阴影。不生成项链、手表、戒指、包等原图中无法确认的小物件。

姿势・手指・接触：
从腰部向前倾倒上身，将头部和肩膀靠近相机，背部不过度弓起，形成柔和的前倾线。双膝微微弯曲，双腿自然分开间距，重心置于中央稍向前。肩膀不耸起，左右温和下沉，脖子不过度伸长。右手接触右膝上方，左手接触左膝上方，不完全显示手掌，手指自然张开贴合膝盖的曲面。

表情・视线：
直视相机，亲切地对视，像欢迎来访的对方而身体靠近那样，做出明亮而无防备的笑容。左右眼睛的睁开程度在自然范围内统一，保留笑容带来的下眼睑小幅上提和脸颊的圆润。表情不是广告用的假笑，而是室内近距离对对方自然回以一笑的瞬间。不在眉间用力，额头或鼻周的表情保持温和。不将视线转向侧面、低头、惊讶脸、挑逗性的半睁眼、过度张嘴。

脸部・妆容：
脸型是柔和的倒三角到卵形轮廓，额头不被刘海过度遮挡，脸颊随着笑容自然上提。眉毛是不太细的深褐色柔和拱形，眼睛横宽，黑眼珠对准相机方向。嘴巴是露出牙齿的明亮笑容，上唇较薄，下唇稍丰满，嘴角两侧都上扬。基础妆容薄而均匀，脸颊有极淡的血色，嘴唇是低饱和的粉米色。上眼睑的线条和睫毛保持照片可见的程度，不添加强烈的眼线、彩色隐形眼镜的不自然边缘、极端的眼影。

头发：
头发是接近黑色的深棕色，自然垂落到肩部以下的直发偏长发。从中央稍稍偏移的分线产生刘海和侧边束，沿着左右脸颊或肩膀外侧。不让头发的轮廓过度融入背景，不像铁丝一样一根根描绘，脸部两侧的体积和长度固定在原图范围内。遵循上身前倾的重力，毛梢分成胸前和背面两侧下垂，不做成空中凝固的均匀帘状。

光源：
主光源是从窗户进入的柔和白天自然光，从脸部正面斜上方照亮，在眼睛中放入小小的反光。额头、脸颊、鼻尖、白T恤有亮度，但不因过曝而丢失轮廓或布料褶皱。在下巴下方、脖子、腋下、膝盖周囲制造柔和的阴影，将阴影方向统一。背景的窗户一侧比人物稍亮以保持白天感，但通过自然的曝光校正避免人物脸部因逆光变暗。辅助光仅限于白色墙壁或地板的弱反射，不添加摄影棚闪光灯的硬阴影、有色照明、强轮廓高光。

颜色・色调：
整体以白色T恤和明亮室内为基调，结合肌肤的暖色、深褐色头发、米色到灰色的背景，形成低饱和的自然色。白平衡是略带暖意的日光，不让肌肤偏向黄橙色，不让白色衣物染上青或绿。从高光到中调的过渡平滑，将脸部的立体感、T恤的褶皱、头发的光泽收在同时可辨识的范围内。以智能手机照片般的直率色调，同时让脸部明部平滑，室内暗部稍留柔和。

材质・细微质感：
背景的墙壁、布料、木质元素比人物降低分辨率，遵循实拍的景深。细节配合智能手机拍摄的自然分辨感，不添加过度的轮廓强调、假的高频噪点、AI特有的精细图案。肌肤上适度保留脸颊、额头、鼻周的细小毛孔、眼角的薄纹、嘴唇的纵纹，不做成均匀的塑料面。

构图・相机：
纵向9:16的画面。人物的视觉中心横向49〜51%，脸部中心也横向48〜52%。头顶余白约7%，左右最窄余白从头发或肩膀各10%以上。脸部中心从画面上端约27%，左右中央50%附近，双目连线固定在上端约25%。头顶到上端的余白约7%，包含头发的头宽约画面宽的24%，肩宽约43%，包含白色T恤的躯干最大宽约61%。相机位置在女性胸部到肩部高度附近，固定前倾的脸在上部中央、白色T恤躯干在中央、双膝和手在下部的流动。相机几乎水平，但保留表现出人物靠近的距离感的轻微透视。背景中等程度模糊，脸部、头发前缘、T恤、双手和膝盖保持可辨识的分辨感。

图像处理・完成：
完成优先看起来像是最新智能手机室内拍摄的一张照片。镜头校正大致自然保持垂直线，同时保留近距离拍摄的轻微透视。去噪到不消逝头发或布料质感的程度，锐度轻微作用于眼睛、嘴部、T恤轮廓。背景虚化具有光学连续性，不在人物周囲制造抠图的白边或光晕。不过度统一肌肤色的局部红润或阴影，即使用于广告也保留日常的温度。脸部检测的局部校正保持弱，对曝光、色温、阴影、高光整体调整，不像单独层那样只让肌肤平滑。

崩溃回避・禁止：
固定相同脸部、头发、白色T恤、前倾姿势、双手与双膝的接触、室内配置、白天光、低饱和完成，不替换为其他服装、其他人物、其他地点。不过度消除脸部的左右不对称，禁止眼球方向差异、重影虹膜、扭曲牙齿、融化耳朵、脖子扭曲。双手必须自然连接到各膝盖，不制造手指增减、融合、关节反转、手腕截断。避免T恤的logo、透视、过度胸部强调、衣物与肌肤融合。不推测生成画面外的脚尖、鞋子、背面、房间全景、随身物品。背景不放置其他人、镜像、照片内人物、可读文字。不做成拼贴、网格、前后比较、多个场景、多个人物、插图、3D渲染、过度美容修整，作为成年女性一人的自然纵向照片来完结。
