カフェの窓辺で自撮りする優雅な日本人女性

Subject: The completed image is fixed as a 9:16 vertical single-person photo. Face center placed at 51% horizontal, 31% vertical; pupils at 27% vertical; cup center at approximately 22% horizontal, 44% vertical. The character's bounding area is 0-100% horizontal, 5-100% vertical, with about 4% white space at the top. The left hand and cup are on the left, long hair and shoulder straps on the right. This ratio, character bounding area, position of face, eyes, hands, and small objects, and white space at top, sides, and bottom are fixed anchors; do not re-center or adjust, nor equalize background white space during each generation. Parts continuing outside the frame stay truncated; do not complete via canvas expansion. Maintain the same woman, same facial features, same hairstyle, same clothing, same pose and contact, same background layout, same lighting, color, material, and treatment. No horizontal flipping, vertical flipping, field of view changes, camera distance changes, face-only enlargement, or character-only reduction. The overlapping order of character and background, the position where the outline reaches the edge of the frame, and the size relationship between foreground and background are fixed. Tolerance for each anchor under normalized coordinates is generally controlled within ±2%; correction that only aligns the face center while shifting hands or objects is prohibited. During final confirmation, use both overall display and enlarged display to check if the same information as the original image is located in the same position. 
Protagonist: A cute and elegant fictional adult Japanese woman, alone at a window seat in a coffee shop, holding a clear plastic cup of iced latte near her cheek, taking a selfie with a smartphone. Captured from the top of the head to below the chest, wearing a top with a light blue small floral pattern on a white base fabric. The number of people is fixed at one, represented as a fictional adult over 20 years old, not a real person. Reproduce only the age impression, body type, visible parts, clothing, and movements confirmable on the screen; do not assign visually undeterminable attributes such as nationality, occupation, or family relationships. Do not replace the character with other face shapes, other body types, or other age groups; even if other characters are visible in the background, do not promote them to the protagonist. Maintain a natural boundary between the protagonist's outline and the background.
Face/Makeup: Face and facial elements in the frame are a small oval shape, thin parallel eyebrows, large dark brownish-black pupils, a thin straight bridge of the nose, and light coral pink lips. The eye area features detailed eyelashes and extremely thin brown eyeliner, with a natural flush on the cheeks. Base makeup is not thick, retaining small fluctuations in skin tone, three-dimensionality of cheeks, nose, and mouth area, and natural pores. Left and right eyes, eyebrows, nostrils, corners of the mouth, and visible teeth alignment are naturally aligned for a human; do not replicate irises or catchlights identically. Makeup is limited to light colors recognizable in the image; do not add heavy eyeshadow, thick eyeliner, artificial fake eyelashes, strong contour correction, excessive whitening, or plastic-like skin.
Hair: Hair is dark brown long straight hair approaching black. Thin bangs, inner-curling strands around the face, and long, lustrous strands flowing from the right shoulder to below the chest. No excessive uniform gloss. Each hair is not unified into the same line; a mix of thick strands, medium strands, and fine flyaways is maintained with continuous flow from root to tip. Hairline, parting, area around the ears, and overlap at the neck or shoulders do not break down. Reflect only wind, humidity, gravity, and contact visible on screen; do not change to other hairstyles, excessive curls, or helmet-like expressions with uniform gloss.
Expression/Gaze: Expression and gaze look directly at the camera with a slight smile and closed mouth. Looking towards the near object while showing the cup, with an intimate feeling of a selfie. Avoid enlarged eyes or juvenile expressions. Direction and focal length of left and right pupils remain consistent; avoid strabismus, different focal points for each eye, or unnatural eye whites. Movement of cheeks, corners of eyes, wings of the nose, and corners of the mouth are linked to the same emotion; do not do fake smiles with only the mouth attached. No tears, strong surprise, anger, sleepiness, flirtatiousness, or romantic assertions in the image; do not add such elements.
Pose/Fingers/Contact: Pose, fingers, and contact are from the perspective of one arm extended toward the smartphone, but the device and the holding hand are outside the frame. The hand on the left side of the frame supports the lower part of the cup, naturally showing five fingers and light pink nails. The edge of the cup is near the cheek but not touching. Shoulders, collarbones, neck, upper arms, elbows, forearms, and wrists in the parts connected within the frame are presented at natural skeletal angles. When hands are visible, do not confuse left and right; five fingers on one hand, number of joints, nail direction, and finger length are natural; contact points for holding objects, pressure, and gravity are consistent. Do not sprout invisible fingers or body parts from the background; avoid arm fusion, double shoulders, elongated necks, or hyperextended joints. The twist of the body orientation relative to the face orientation is fixed within the range of the original image.
Clothing/Accessories: Clothing and accessories are a summer top with small light blue and gray floral patterns on a white base fabric, a small knot at the center of the chest, and thin straps. A beige bag strap is on the right shoulder. A thin silver chain and a small heart pendant. Do not change colors, necklines, sleeves, straps, knots, stitching, hardware, or the presence of decorations. The fabric does not cling like paint; small wrinkles are generated based on stretch, drape, thickness, gravity, and contact. Visible accessories maintain the same shape, position, holding style, and material; do not add brand text or fictional logos. Do not complete by speculating on the overall clothing outside the frame or unconfirmed accessories.
Location/Time/Background: Location and background are a bright coffee shop or a window seat near a station. Background consists of white tile-like grids and soft blurred window reflections; furniture or other people are not prominent. A small blue bottle-shaped mark is visible on the cup, but no text or real brand. Time period is fixed to the brightness readable from the light in the frame; do not replace with night views, sunsets, studio backgrounds, or other times/locations. Maintain the order and overlap of foreground, midground, and background; orientation of visible structures such as horizons, walls, windows, floors, furniture, and plants is natural. The smartphone, the other hand taking the photo, everything below the waist, and the full view of the coffee shop are outside the frame. Do not create invisible drink names, shop names, menus, food on the table, or extra characters. The background is not simplified to white space, nor is it filled with information not present in the original image.
Composition/Camera: Composition and camera are a vertical smartphone selfie with an extended arm, equivalent to 28-35mm. The face is placed near the center while including the cup in the same frame, suppressing facial distortion. Focus on the pupils and face; the cup and hand have sufficient readable resolution; background is slightly blurred. Fixed vertical cropping, shooting distance, camera height, pitch angle, and front-facing/diagonal orientation relative to the subject. Maintain the natural resolution of a smartphone; avoid wide-angle barrel distortion, central facial swelling, or elongation of only legs or arms. Focal plane matches the protagonist's face or the image theme; background blur amount and outlines are equivalent to the original image. No unnatural uniform blur like cutout outlines, double outlines, or generated blur swirls.
Light Source: Light source is bright diffused daylight coming through the window, entering from the front left, forming a large catchlight in the pupils and producing soft reflections on the bridge of the nose, cheeks, fingertips, and cup edge. Indoor white walls serve as fill light, preventing the chin from becoming dark. Direction of main light source, auxiliary reflections, and shadows remain consistent; apply the same lighting conditions to the face, hair, clothing, accessories, and background. Catchlights and material reflections correspond to the light source position; do not add multiple contradictory suns, unrelated spotlights, or artificial all-around rim lighting. Highlights retain subtle gradations, while preventing skin, white cloth, sky, clouds, or windows from blowing out to pure white. Shadows also retain color information and reflected light.
Color/Tone: Colors and tones center on white, light blue, beige, milk coffee color, and dark brown, maintaining a clean low-to-mid saturation. Skin is neutral, with only the blue of the pattern and the cup mark as small accent colors. White balance matches the scene lighting, suppressing mutual contamination of skin, white, black, and background colors. Smooth connection from highlights to midtones to shadows; avoid HDR-style local contrast, fluorescent colors, excessive blue-orange separation, crushed blacks, or vignetting around outlines. Saturation maintains the relationship between main and accent colors in the image; do not change clothing or background hues to other colors.
Materials/Fine Textures: Materials and fine textures distinguish between the edge and lid of the transparent cup, the black straw, the opaque milky white of the iced latte, nails, the thin weave of patterned cloth, the matte faux leather of the bag, hair strands, and skin pores. Skin is not unified as a noise surface; naturally vary pore size, fine fuzz, blood color, dry/wet differences, and gloss differences according to the area. Hair, cloth, wood, ceramics, sand, water, metal, and plastic are not unified in gloss; individually depict surface roughness, transparency, reflection range, and edge thickness. High-definition enhancement does not create fake text, regular repetitive patterns, excessive sharpness, or grid-like noise. When enlarging, confirm not only the outlines but also tiny shadows at contact surfaces, translucent edges, surface irregularities, and density of fiber or grain directions. On the other hand, do not exaggerate pores or fibers invisible to the naked eye into a rough texture, guarding the information amount appropriate for the shooting distance.
Image Processing/Finishing: Image processing is finished as a real smartphone photo or natural portrait photo. Exposure, color temperature, contrast, sharpness, saturation, and noise reduction are performed moderately, maintaining the brightness and atmosphere of the original image. Do not smooth the skin separately as if it were a different layer; pupils, teeth, and lips are not overemphasized. Retain slight sensor grain and natural gradations; do not lean toward illustrations, 3DCG, wax figures, or over-composited photos for advertising. During local outline correction, do not let fine hair lines, eyelashes, fingertips, clothing edges, or accessory edges melt into the background, nor create white borders. After noise reduction, do not unify the grain of skin, cloth, hair, and background; each maintains depth and material differences. Tone curves do not excessively compress highlights; focus on the face and clothing in the midtones, and do not overly lift shadow information to flatten the image. Do not post-add chromatic aberration, excessive vignetting, artificial light leaks, or lens flares. Final output does not insert text, subtitles, borders, watermarks, signatures, UI, or models; output only one 9:16 photo.
Deformation Avoidance/Prohibitions: Highest priority condition for avoiding collapse; prohibited to resemble real people, de-age/miniaturize, replace with others, multiply people, facial left-right asymmetry, inconsistent pupil shapes, fused teeth, overlapping nostrils, deformed ears, or poor neck-shoulder connection. When hands are present, extra fingers, missing fingers, fused fingers, reversed palms, abnormally long nails, or fingers penetrating objects are prohibited. Clothing prohibits disappearing straps or sleeves, fusion with the body, interrupted patterns, or extra perspective. Background prohibits curved horizon or wall lines, dissolving furniture or vessels, giant distant figures, or unreadable text that looks readable. Regarding invisible elements, the smartphone, the other hand taking the photo, everything below the waist, and the full view of the coffee shop are outside the frame. Guard the boundary of not creating invisible drink names, shop names, menus, food on the table, or extra characters; do not generate parts outside the frame or unknown parts. Beauty filters, excessive face slimming, eyeball enlargement, extreme breast/waist emphasis, overt sexual performance, low angles just to incite body parts, other clothing, other backgrounds, other light sources, other seasons, logos, brands, or watermarks are not added.

头发：  
头发为接近黑色的深棕色长直发。薄刘海、脸周内卷的发束、从右肩流至胸部下方的长而有光泽的发束。不做过度均匀光泽。每根头发不统一为相同线条，混合粗发束、中等发束、细碎后发，从发根到发梢保持连续流动。发际线、分线、耳周、颈部或肩部的重叠不崩坏。只反映画面可见的风、湿气、重力、接触，不改为其他发型、过度卷发、均匀光泽的头盔状表现。  
表情・视线：  
表情和视线直视镜头，闭嘴微微微笑。一边展示杯子一边将视线转向近处的对象，带有自拍的亲密感。避免眼睛放大或幼态表情。左右瞳孔的方向和焦距保持一致，避免斜视、单眼焦点不同、不自然的眼白。脸颊、眼尾、鼻翼、嘴角的动作联动相同情感，不做仅嘴部贴上的假笑。图像中无泪水、强烈惊讶、愤怒、睡意、挑逗、恋爱断定等，不添加此类元素。  
姿势・手指・接触：  
姿势、手指、接触为单臂伸向智能手机方向的视角，但终端和握持手在画面外。画面左侧的手支撑杯子下部，自然显示五指和淡粉色指甲。杯子边缘靠近脸颊但不接触。肩部、锁骨、颈部、上臂、肘部、前臂、手腕在画面内连接的部分以骨骼自然角度呈现。可见手部时不混淆左右，一只手上五指、关节数、指甲方向、指长自然，物体握持接触点、压力、重力一致。不从背景生出不可见的手指或身体部位，避免手臂融合、肩部双重、颈部伸长、关节反曲。身体朝向与脸部朝向的扭曲固定在原图像范围内。  
服装・小物：  
服装和小物为白色底布上印有小淡蓝色和灰色花纹、胸口中央小结、细肩带的夏季上衣。右肩有米色包带。细银链和小爱心吊坠。不改变颜色、领口、袖子、肩带、结、缝合、金具、装饰的有无。布料不贴身如涂漆，依伸缩、垂感、厚度、重力、接触产生小皱褶。可见小物保持相同形状、位置、握持方式、材质，不添加品牌文字或虚构标志。不推测画面外服装整体或未确认配饰来补全。  
地点・时间・背景：  
地点和背景为明亮咖啡店或车站附近的窗边座位。背景为白色瓷砖状网格和窗户反射柔和模糊，家具或其他人不突出。杯子上可见小蓝色瓶状标记，但不做文字或真实品牌。时间带固定为画面内光线可读的明亮度，不替换为夜景、日落、摄影棚背景等其他时间・地点。保持前景、中景、远景的顺序和重叠，水平线、墙、窗、地板、家具、植物等可见结构的朝向自然。智能手机、拍摄中的另一手、腰部以下、咖啡店全景在画面外。不创作不可见的饮料名、店名、菜单、桌上料理、额外人物。背景不简化为空白，同时不以原图像中无的信息填满。  
构图・相机：  
构图和相机为伸臂纵向智能手机自拍，相当于28～35mm。脸部置于中央附近，同时将杯子纳入同一画面，抑制脸部扭曲。对瞳孔和脸部对焦，杯子和手有足够可读分辨率，背景轻微模糊。固定纵向裁剪、拍摄距离、相机高度、俯仰角、与被摄体的正对・斜向。保持智能手机自然的解像感，避免广角桶形扭曲、脸部中央膨胀、仅腿或臂伸长。焦平面匹配主角脸部或图像主题，背景虚化量和轮廓相当于原图像。不做轮廓抠图般的非自然均匀虚化、二重轮廓、生成虚化的漩涡。  
光源：  
光源为窗户传入的明亮漫射日光，从正面左侧进入，在瞳孔形成大捕捉光，在鼻梁、脸颊、指尖、杯子边缘产生柔和反射。以室内白色墙壁为辅助光，不使下巴变暗。主光源、辅助反射、阴影方向保持一致，对脸部、头发、服装、小物、背景应用相同照明条件。捕捉光和材质反射与光源位置对应，不添加多个矛盾太阳、无关聚光灯、轮廓全周人工发光。高光保留细微阶调，同时不使肌肤、白布、空、云、窗户白飞。阴影也保留色信息和反射光。  
颜色・阶调：  
颜色和阶调以白、淡蓝、米色、奶咖啡色、深棕色为中心，保持清洁的低～中饱和度。肌肤为中性，仅花纹的蓝和杯子标记作为小点缀色。白平衡匹配场景光线，抑制肌肤、白、黑、背景色的相互污染。从明部到中间调、暗部平滑连接，避免HDR风局部对比、荧光色、过度青橙分离、黑压、轮廓周围晕影。饱和度维持图像内主色与点缀色的关系，不将服装或背景色相改为其他色。  
材质・细微质感：  
材质和细微质感区分透明杯子的边缘和盖子、黑色吸管、冰拿铁的不透明奶白色、指甲、花纹布的薄织、包的哑光人造革、发束、肌肤毛孔。肌肤不统一为噪声面，根据部位自然变化毛孔大小、薄绒毛、血色、干湿差、光泽差。头发、布、木、陶器、沙、水、金属、塑料等不统一光泽，个别描绘表面粗糙度、透明度、反射范围、边缘厚度。高精细化不制造假文字、规则重复图案、过度锐利度、格子状噪声。放大显示时，不仅轮廓，还确认接触面的微小阴影、半透明边缘、表面凹凸、纤维或颗粒方向的密度。一方面，不夸张肉眼不可见的毛孔或纤维而转为粗糙质感，守护与拍摄距离相称的信息量。  
图像处理・完成：  
图像处理作为实拍智能手机照片或自然肖像照片完成。曝光、色温、对比度、清晰度、饱和度、降噪适度进行，维持原图像的亮度和空气感。不将肌肤单独如其他图层般平滑，瞳孔、牙齿、嘴唇也不过度强调。保留轻微传感器颗粒感和自然阶调，不偏向插图、3DCG、蜡像、广告用过度合成照片。轮廓局部修正时，不让头发细线、睫毛、指尖、服装边缘、小物边缘溶入背景，反之也不制造白色镶边。降噪后也不统一肌肤、布、头发、背景的颗粒感，各自保持深度和材质差异。色调曲线不过度压缩明部，以中间调的脸部和服装为主角，不过度提升暗部信息而平板化。不后加色差、过度周边减光、人工光泄漏、镜头光晕。最终输出不插入文字、字幕、边框、透水印、签名、UI、模型，仅输出一张9:16照片。
