Japanese Woman Leaning Down Outdoor Stairs Smartphone Style | 户外灰色楼梯俯身低头的日本女性

Prompt (English):

Subject:
On outdoor grey stairs, photographing a fictional adult Japanese woman, she leans down, looking down below—in this subject image, the finished frame is vertical 9:16, using a single independent photo; only one protagonist, no left-right flipping of the person, replacement with others, clothing changes, or background reorganization; preserve natural resolution like smartphone shooting, slight close-up perspective difference, and incompleteness of instantaneous composition; do not replace the ethnic appearance of the person with other characteristics, but present with an identifiable natural styling of a Japanese woman. A young adult over 20 years old, a natural moment of adjusting posture supported by hands during movement. Visible from the top of the head to the upper part of the shorts, both arms, and parts of the hands. The area below the stairs, toes, building use, surrounding people, etc., are all generated outside the frame.

Location, Time, Background:
Composed of grey outdoor stairs, horizontal lines of steps, and a bright wall or handrail surface on the right—in the depth of this scene, the time period is limited to the range interpreted from the frame's light, without adding new objects determined to be morning, noon, or night; maintain the overlapping of foreground, midground, and background, ensuring the background does not unnaturally bend along the person's silhouette; background information is more low-key than the person but is not replaced by monochrome blur; do not generate unconfirmable windows, doors, signs, furniture, pedestrians, vehicles, scenery, or reflections within the frame. Sunlight enters from above, with light and shadow on the edges of the steps and the wall. The perspective of the stairs and the number of steps are kept only within the visible range of the frame and are not replaced with other locations.

Clothing and Accessories:
A light beige to grey-beige sleeveless rib-knit top and light blue denim shorts—in this outfit reproduction, align fabric seams, openings, shoulder or chest boundaries, overlaps, and stretching directions with the pose; do not make changes that increase exposure or emphasize sexiness. The top fits the body, preserving vertical ribs and shoulder edges. Do not add accessories, bags, or hats; fix the clothing type, color, and length. Shorts only show the waist and hem parts, without forcibly adding pockets or metal parts.

Pose, Fingers, Contact:
The upper body leans forward, both arms extend downward, hands supported near the stairs or knees—in the continuity of this action, the thickness of the arms and the positions of the joints are consistent on the left and right, without adding extra elbows or wrists. Shoulder height and elbow angles differ slightly on the left and right, with the center of gravity at the front of the body. The neck and back are connected with natural curves, without changing the depth of the crouch, and without modifying it to a standing or sitting posture.

Expression and Gaze:
The face is slightly downward, and the gaze also falls toward the feet or hands—in this sense of distance and emotion, integrate the pupil direction, upper eyelid, lower eyelid, eyebrows, cheeks, and mouth as one emotional whole; do not add emotions or stories to the expression that cannot be confirmed by the image. The mouth is relaxed, not a smile, but does not show fatigue or displeasure. Preserve the weight of the eyelids, the quiet shadows on the cheeks, and the moment just before looking up. Do not change to looking at the camera, blinking, a toothy smile, a crying face, or a provocative expression.

Face and Makeup:
A small oval face, gentle forehead and cheeks, slender jawline. Skin is a bright neutral beige, with elegant warm tones under the sunlight on the right. Eyebrows are a natural dark brown shape, pupils are downward, preserving the part covered by the upper eyelid. The bridge of the nose is thin and straight, lips are pale rose-beige, lightly closed. The front face remains unchanged, do not widen the eyes, avoid heavy makeup or porcelain-like skin.

Hair:
Thick deep dark brown hair tied low behind the head, preserving sparse bangs and sideburns—in this reproduction of hair flow, hair strands are not filled with single-line depictions but are overlaid with hair bundles of different thicknesses, a sense of wholeness, shadows, and a small amount of flying strands; the boundary with the scalp is natural, and bangs do not invade the eyebrows or pupils; the boundary with the background does not produce cut-out white edges or fusion, and only restrained light transmission and luster are placed on the light source side. When leaning forward, thin hair bundles fall near the cheeks, and the silhouette under the sunlight presents a soft luster. The hair tie and hair length are limited to the visible range, and long hair is not added to the back.

Light Source:
Natural sunlight from the upper right of the frame is the main light source—in this lighting design, the direction of light falling on the skin, hair, fabric, and background is all consistent; place natural shadows on the opposite side of the main light source under the nose, under the chin, inside the hair, and at clothing overlaps, ensuring shadow tones are not muddy. The hair silhouette, right cheek, right shoulder, arm, and stair edges are bright, while the left face and body retain soft shadows. The stairs and walls reflect faint light but do not flatly lift the dark areas. Do not change to front flash, sunset, neon, or studio multi-light lighting.

Color and Tone:
A low-saturation color scheme consisting of grey-beige, light denim blue, concrete grey, natural warm skin tones, and thick tea-colored hair—in this color scheme and tone, preserve the gradients of highlights, midtones, and shadows to prevent skin overexposure, hair clogging, and loss of clothing texture; the white balance matches the main light source, without destroying the color relationship between the skin, white-colored fabrics, and grey background; do not overall increase saturation or sharpness, creating the tone of a natural smartphone photo. Highlights are warm, shadows are slightly cool. The top does not lean toward pure white or yellow, and the denim is not changed to a vivid blue.

Material and Subtle Texture:
Skin pores, fine vellus hair, subtle shadows on arms, and lip lines are preserved—in this texture design, do not attach uniform particles to the skin, but change pore visibility based on bright parts and shadows; avoid extreme JPEG compression distortion, while not pursuing commercial CG-like perfection, but rather preserving the subtle graininess of a natural shoot. Hair shows both back hair and bundles. Vertical grooves of the rib knit, weave and stitching of the denim, powdery unevenness of the concrete, and wear on the steps are distinguished. Details in the sunlight parts are not overexposed, and shadow noise is not completely eliminated.

Composition and Camera:
Finished frame is vertical 9:16—in this frame configuration, calculated as 100% width and 100% height, fix the center of the face at 49-51% horizontal, the line connecting the eyes at 27-32% of the upper end, head-top margin at 3-7%, and the overall visual center of the person at 45-55% horizontal; the head and hair are at least 4% from the left and right edges, the face height accounts for about 18-25% of the frame height, and from the top of the head to the lowest visible part of the lower body is contained within 88-96% of the frame height; the depth of field is such that the face and main clothing are clear, and the background is gently softened. Captured vertically with a smartphone from a position higher than the woman's head, tilted diagonally downward. Naturally present the depth extending from the face, shoulders, arms, top, and shorts. The main focus is placed on the face and upper body, with the stairs slightly softened. Preserve the slight parallax of close-up shooting but avoid fisheye distortion where the head or hands bulge.

Image Processing and Completion:
The atmosphere of the scene where the woman in a light-colored top on the outdoor stairs is supporting herself with her hands and looking down is not damaged, so first adjust the low-frequency large blocks of light and dark, then adjust the medium shapes of the face, clothing, and background, and finally fine-tune subtle elements such as hair strands or cloth patterns—in this photo-like completion, the completion level is a real-shot smartphone photo; suppress chromatic aberration, false colors, halos, and double outlines, preserving natural lens softness; the tone curve is rich in midtones, not clipping black or white ends; unify the light, color, texture, and graininess of the entire frame.

Collapse Avoidance and Prohibitions:
Fix the same adult woman, same tied hair, downward gaze expression, leaning forward pose, arm positions, beige top, light denim, stair configuration, upper right light, color, and texture—to protect this finished image, do not generate extra faces, eyes, ears, arms, hands, fingers, legs, shadows, or reflected images; absolutely do not add text, numbers, subtitles, logos, brands, watermarks, signatures, or border lines; do not change the same woman, face shape, age sense, hairstyle, clothing, pose, contact, background configuration, camera position, light source, color, material, or completion; do not flip the body or clothing left and right. Do not turn the face to the front, do not damage fingers, elbows, shoulders, clothing edges, or stair perspective. Do not add extra people, hands, fingers, bags, text, logos, or watermarks. Do not create legs, shoes, or surrounding landscapes outside the frame.

被摄主体：
在室外的灰色楼梯上，拍摄一位虚构的成年日本女性，她弯下身子，低头看着下方——在这个被摄主体形象中，完成画面为纵向9:16，采用单张独立照片；主角仅一人，不进行人物左右翻转、替换成他人、服装变更、背景重组；保留如同智能手机拍摄般的自然分辨率、近距离的轻微远近差、瞬间构图的不完整性；不将人物的民族外貌替换为其他特征，而是以日本人女性可辨识的自然造型呈现。20岁以上的年轻成人，在移动途中用手支撑调整姿势的自然瞬间。从头顶到短裤上部、双臂和部分手部可见。楼梯下方、脚尖、建筑物用途、周围人等均置于画面外生成。

地点・时间・背景：
灰色的室外楼梯、台阶的水平线、右侧的明亮墙壁或扶手面构成——在这个场景的深度中，时间段仅限于从画面光线解读的范围，不添加断定为早晨、中午、夜晚的新景物；维持前景・中景・背景的重叠，确保背景不沿人物轮廓不自然弯曲；背景信息比人物更低调，但不替换为单色模糊；画面内不生成无法确认的窗户、门、标牌、家具、行人、车辆、景色、反射。上方阳光照入，台阶边缘和墙面有明暗。楼梯的透视和台阶数仅保留画面可见范围，不替换为其他地点。

服装・小物：
明亮的米色至灰米色的无袖罗纹针织上衣，以及浅蓝色的牛仔短裤——在这个装束再现中，将布料的缝合线、开口部、肩部或胸口的边界、重叠、拉伸方向与姿势一致；不进行增加暴露或性感强调的变更。上衣贴合身体，保留纵向罗纹和肩周边缘。不添加配饰、包、帽子，固定服装种类、颜色、长度。短裤仅显示腰部和下摆部分，不强行添加口袋或金属部件。

姿势・手指・接触：
上身向前倾倒，双臂向下伸展，手撑在楼梯或膝盖附近——在这个动作的连贯性中，可见手臂的粗细和关节位置左右一致，不额外增加肘部或手腕。肩部高度和肘部角度左右略有差异，重心位于身体前方。颈部和背部以自然曲线连接，不改变蹲伏深度，不修改为直立或坐姿。

表情・视线：
脸部略微向下，视线也落在脚下或手部方向——在这个距离感和情感中，将瞳孔方向、上眼睑、下眼睑、眉毛、脸颊、嘴部作为一个情感整合；不向表情添加图像无法确认的情感或故事。嘴部放松，不是笑容，但不表现出疲劳或不悦。保留眼睑的重量感、脸颊的静谧阴影，以及下一刻即将抬头的一瞬。不改为注视镜头、眨眼、露齿笑容、哭脸、挑逗表情。

脸部・妆容：
小巧的卵形脸、平缓的额头和脸颊、细长的下巴线。皮肤为明亮的 neutral 米色，右侧阳光下带有淡雅的暖色调。眉毛为深褐色的自然形状，瞳孔向下，保留上眼睑遮盖的部分。鼻梁细直，嘴唇为淡玫瑰米色，轻闭。正面脸不变，不睁大眼睛，避免浓妆或瓷器般的肌肤。

头发：
浓深暗褐色的头发在脑后低低扎起，保留稀疏的刘海和鬓角后发——在这个发丝流动再现中，发丝不以单根描绘填充，而是叠加粗细不同的发束、整体感、阴影、少量飞散发丝；与头皮的边界自然，刘海不侵入眉毛或瞳孔；与背景的边界不产生抠图白边或融合，光源侧仅放置克制的透光和光泽。前倾时细发束落在脸颊附近，阳光下的轮廓呈现柔和光泽。发结和头发长度仅限于可见范围，不添加长发至背部。

光源：
画面右上方自然阳光为主光源——在这个照明设计中，皮肤、头发、布料、背景落光方向全部一致；鼻下、下巴下、头发内侧、衣物重叠处放置主光源反侧的自然阴影，确保阴影色调不浑浊。头发轮廓、右脸颊、右肩、臂部、楼梯边缘明亮，左侧脸部和身体保留柔和阴影。楼梯和墙壁反射微弱光线，但不平坦提升暗部。不改为正面闪光、日落、霓虹、摄影棚多灯照明。

颜色・色调：
灰米色、淡牛仔蓝、混凝土灰、皮肤自然暖色、头发浓茶构成的低饱和度配色——在这个配色和色调中，保留明部、中间调、暗部的渐层，防止皮肤过曝、头发堵塞、衣物质感消失；白平衡匹配主光源，不破坏皮肤、白系布料、灰色背景的色关系；不整体提升饱和度或清晰度，营造自然智能手机照片的色调。明部温暖，阴影略带冷调。上衣不偏向纯白或黄色，牛仔不改为鲜艳蓝色。

材质・细微质感：
皮肤毛孔、细绒毛、臂部细微阴影、嘴唇细线保留——在这个质感设计中，不向皮肤贴附均匀颗粒，根据明亮部分和阴影改变毛孔可见度；避免JPEG极端压缩失真，同时不追求商业CG般的完美无缺，而是保留自然拍摄的细微颗粒感。头发同时显示后发和发束。罗纹针织的纵向凹槽、牛仔的织纹和缝合、混凝土的粉状不均、台阶的磨损加以区分。阳光部分的细节不致过曝，阴影噪点不完全消除。

构图・相机：
完成画面为纵向9:16——在这个画面配置中，以画面宽度100%、高度100%计，将脸部中心固定在横向49〜51%、连接双眼的线在上端27〜32%、头顶余白3〜7%、人物整体视觉中心横向45〜55%；头部和头发至少距左右端4%，脸部高度约占画面高度18〜25%、从头顶到可见下半身最下端收纳在画面高度88〜96%；景深程度为脸部和主要衣物清晰，背景温和柔化。以智能手机从女性头部更高位置靠近，斜向下方的纵向拍摄。自然呈现脸部、肩部、臂部、上衣、短裤延伸的深度。主要焦点置于脸部和上半身，楼梯略微柔化。保留近摄的轻微远近差，但避免头部或手部膨胀的鱼眼失真。

图像处理・完成：
室外楼梯上淡色上衣女性手撑低头注视的场景空气感不损，因此先调整低频大块明暗、次调整脸部・衣物・背景的中等形状、最后微调发丝或布纹等细微元素——在这个照片感完成中，完成度为实拍智能手机照片；抑制色差、伪色、光晕、双重轮廓，保留自然镜头柔和度；色调曲线丰富中间调，不裁剪黑白两端；统一画面整体的光线、颜色、质感、颗粒感。

崩溃回避・禁止：
固定同一成年女性、同一扎发、下视线表情、前倾姿势、双臂位置、米色上衣、淡色牛仔、楼梯配置、右上方光线、颜色和质感——为了守护这个完成像，不生成多余的脸、眼、耳、臂、手、指、腿、影、反射像；绝不添加文字、数字、字幕、标志、品牌、水印、签名、边框线；不改变同一女性、脸型、年龄感、发型、衣装、姿势、接触、背景配置、相机位置、光源、颜色、材质、完成；不左右翻转身体或衣物。不将脸转向正面，不破坏手指、肘、肩、衣物边缘、楼梯透视。不添加多余人、手、指、包、文字、标志、水印。不创作画面外的腿、鞋、周边景观。
