室内角落蜷坐低清闪光写实人像

4:5 vertical, realistic indoor snapshot style portrait, adult East Asian female, single person, located in an ordinary indoor wall corner or corridor corner. The person is sitting curled up on the left side of the frame, one knee raised high near the chest, hands naturally folded and holding the knee, upper body slightly gathered forward, shoulders relaxed, head tilted slightly to the right, face towards the camera, eyes resting gently in the direction of the lens, expression quiet, slightly detached, with a bit of a spaced-out feeling, no strong aggressive gaze, no exaggerated expressions.

Dark long hair naturally loose, some strands falling along the shoulders and chest. Wearing a black or deep charcoal sleeveless top, paired with deep grey-black or black loose trousers, the overall clothing remains low-key and dark-colored, forming a large area of dark mass. A small amount of low-weight layered necklaces or small pendants can be on the chest, but accessories must not compete with the face and posture.

The composition must maintain a clear asymmetrical relationship. The figure is concentrated on the left half of the frame, the head is in the upper left area, the raised knee occupies the middle-lower part, and the hands rest on top of the knee. The right side retains a large area of low-frequency empty wall and a dark doorway or dark opening, forming a quiet negative space. The background only needs simple wall corners, light pink-grey or warm grey-beige walls, and a dark opening on the right; do not add complex furniture and decorations. The vertical line of the wall corner needs to clearly exist, cutting the space into the figure area on the left, the light wall area in the middle, and the dark area on the right.

The lighting uses a close-up frontal flash or hard fill light snapshot effect in a low-illumination indoor environment. The face, hands, shoulders/arms, and the front edge of the knee are lit by the flash, skin tones are warm, background brightness is low, and the dark doorway area on the right quickly falls into darkness. The overall feel is a real personal snapshot, no high-end commercial lighting, no uniform softboxes.

Color relationship control: about 31% near-black warm shadows, 25% grey-pink-beige wall, 17% warm skin highlights, 13% dark grey-black trousers and clothing middle layers, 8% warm grey-brown transition colors, 6% low-saturation warm red lip color and slight flush. The overall tone remains low-saturation, dark-colored, with a flash snapshot feel, without adding neon colors or bright decorations.

Imaging texture:
The whole image uniformly retains low definition, light soft focus, fine grain, slight shadow color noise, and a bit of network compression feel. The face, hair, hands, trousers, walls, and doorway are degraded together lightly; do not just retouch the face to be very sharp. Highlights have a slight whitening after the direct flash. The overall look is like a personal indoor nighttime casual snapshot, no high-definition commercial portraits, no studio retouching. Softening and grain must apply to the entire image.

Soran Three-layer Natural Watermark:
The first layer of readable watermark: the exact text “Soran” clearly readable once, appearing naturally on the front of a small silver-grey metal engraved pendant on the chest, or fixed in the form of a tiny light grey metal nameplate on the black top near the collarbone or shoulder strap, like a real jewelry brand or clothing brand logo, close to the face, discernible to the naked eye, while naturally affected by flash, highlights, and low-res compression.
The second layer of hidden watermark: the hidden “Soran” integrated into the arrangement of long hair highlights, black trouser folds, and subtle wall grain patterns.
The third layer of microscopic watermark: the miniature “Soran” naturally formed by necklace links, pendant engravings, fabric stitching, hair strand intersections, and low-illumination grain arrangements.
All Soran must be integrated with jewelry, clothing, and environment materials, obvious but natural, no floating text.

Negative Prompts:
Centered person, ordinary sitting posture, standing, hands off knee, knee not raised, no white space on the right, background complex furniture, luxurious interior, excessive decoration, uniform soft light, cinematic lighting, fresh daytime feel, neon colors, bright background, commercial blockbuster, studio photo, sharp focus, ultra detailed, 8k, crisp clean image, HDR, commercial beauty retouching, over-sharpening, face alone in high definition, plastic skin, porcelain white skin smoothing, AI beauty face, anime face, strong aggressive gaze, exaggerated smile, extra people, extra arms, extra fingers, incorrect hand structure, extra readable text, extra brand names, external watermark, sticker-like logo, detached letters, captions, subtitles, floating text, oversized branding, flat pasted logo

4:5 竖幅，真人写实室内快照风人像，成年东亚女性，单人，位于普通室内墙角或走廊角落。人物蜷坐在画面左侧，一条膝盖高高抬起靠近胸前，双手自然叠放并抱住膝盖，上身轻微向前收拢，肩膀放松，头部微微偏向右侧，脸朝向镜头，眼神轻轻停在镜头方向，神情安静、略疏离、带一点放空感，不做强攻击性凝视，不做夸张表情。

深色长发自然披散，部分发丝沿肩膀和胸前垂落。穿黑色或深炭黑无袖上衣，搭配深灰黑或黑色宽松长裤，整体服装保持低调暗色，形成大面积主体暗块。胸前可有少量低权重叠戴项链或小吊坠，配饰不能抢脸部和姿态。

构图必须保留明显的不对称关系。人物集中在画面左半边，头部位于左上区域，抬起的膝盖占据中下部，双手落在膝盖顶部。右侧保留大面积低频空墙和一块深色门洞或黑暗开口，形成安静的负空间。背景只要简单墙角、浅粉灰或暖灰米色墙面、右侧深色开口即可，不加入复杂家具和装饰。墙角竖线需要清楚存在，把空间切成左侧人物区、中间浅墙区、右侧暗区。

光线采用低照度室内环境下的近距离正面闪光或硬补光快照效果。脸、手、肩臂和膝盖前沿被闪光打亮，肤色偏暖，背景亮度较低，右侧暗门区迅速跌入黑暗。整体有私人随手拍的真实感，不做高级商业布光，不做均匀柔光箱。

色彩关系控制为：约31%近黑偏暖暗部，25%灰粉米色墙面，17%暖肤色亮面，13%深灰黑裤装和服装中间层，8%暖灰棕过渡色，6%低饱和暖红唇色与轻微血色。整体保持低饱和、暗色、闪光快照感，不加入霓虹色和鲜艳装饰。

成像质感

全图统一保留低清、轻柔焦、细颗粒、轻微暗部色噪和一点网络压缩感。脸、头发、手、裤装、墙面和门洞一起轻度退化，不能只把脸修得很锐。亮部有一点闪光直打后的微微泛白，整体像私人室内夜间随手快照，不做高清商业人像，不做影楼精修。柔化和颗粒必须作用于整张图。

Soran 三层自然水印

第一层可读水印：精确文字 “Soran” 清晰可读一次，以小型银灰金属刻字自然出现在胸前吊坠正面，或以细小浅灰金属铭牌形式固定在黑色上衣靠近锁骨或肩带位置，像真实首饰品牌或服装品牌标识，离脸近，肉眼可辨，同时受闪光、高光和低清压缩自然影响。

第二层隐藏水印：隐藏的 “Soran” 融入长发高光排列、黑色裤装褶皱和墙面细微颗粒纹理中。

第三层微观水印：微型 “Soran” 由项链链节、吊坠雕纹、衣料针脚、发丝交叉和低照度颗粒排列自然形成。

所有 Soran 都必须与首饰、服装和环境材质融合，明显但自然，不做悬浮文字。
