Create a restrained studio fashion portrait with an exact vertical aspect ratio of 736:981 in a full-body vertical crop. The raised hand above the head is physically cropped by the top edge with 0% headroom, and both feet are cropped by the bottom edge. Position the subject slightly right of center, occupying approximately 83% of the frame. Leave the largest negative space as a warm off-white wall covering about 24% of the frame from the upper-left to middle-left. Place a worn wooden folding chair in the center foreground, vertically dividing the composition and partially obscuring the torso and pelvis. Use a camera positioned approximately at eye level with a 3–5° downward tilt. The torso angles diagonally away from the camera while the face turns back toward the lens. The subject looks directly into the camera beneath low, heavy eyelids. Use a medium camera distance with a mild telephoto portrait-lens perspective. Avoid wide-angle distortion, oversized head perspective, and noticeable camera roll. Pose: The subject sits behind the chair, leaning deeply over the chair back. The shoulder line descends diagonally toward the lower right. One elbow presses firmly on the top rail of the chair back for support, with the forearm crossing beneath the face. The opposite arm bends upward, with the palm gripping the hair above the crown. The pelvis sits low behind the chair. Both knees are spread wide and cropped by the bottom of the frame. Weight is naturally supported through the chair, the supporting elbow, and the seated pelvis, maintaining realistic spinal and wrist alignment. Use one old wooden folding chair with chipped white paint, dark brown wood, two horizontal back slats, and a visible seat. Approximate placement: x23–66, y39–96, occupying about 31% of the frame. The chair remains in front of the subject, obscuring the center torso and pelvis. Pose anchors: head center x48 y16; raised hand x43 y2 (cropped by top edge); elbow touching chair back x37 y36; wrist beneath face x48 y30; left knee x16 y76; right knee x84 y78; both feet cropped. Depth order: foreground—chair and arms; focus plane—face, upper torso, chair back; mid-ground—spread thighs; background—plain warm gray off-white studio wall. Use an adult editorial long-line silhouette with visible proportions of approximately 18% head width, 19% head height, and 52% shoulder width. The neck remains visible but partially compressed by the folded posture. Maintain a relatively small head, mature skeletal structure, long forearms, high natural waist and pelvis, and long thighs. The lower body is partially hidden by the chair and crop. Never invent unseen calves or feet. If the target image lacks body information, use these adult proportions. Never produce infantilized proportions, oversized heads, short legs, or unusually small hands or feet. Illuminate the scene with one directional studio light from camera-right. Brightest areas are the right side of the face, right ridge of the nose, upper forehead, and the chipped white paint on the chair's right side. Preserve deep shadows around the left eye socket, left temple, and lower left face. Maintain warm beige skin tones with cool indigo clothing and cool gray-brown shadows. Bloom is essentially zero. Keep the image sharp with no meaningful blur. Do not introduce motion smear, double edges, optical defocus, or halation. Exposure behaves like a spatial mask: the wall at x0–30 remains high-key warm off-white; the left half of the face (x39–48) stays in shadow; the right cheekbone and forehead (x50–61) receive localized highlights. Dark clothing remains at least two tonal stops darker than

创作一张克制风格的影棚时尚肖像照，严格采用 736:981 的竖向宽高比，进行全身竖向裁切。头顶上方的抬起手部被画面顶边物理裁切，预留 0% 顶部留白；双脚被画面底边裁切。人物位于画面中心略偏右，占画面约 83%。最大负空间为暖色调近白色墙面，覆盖画面约 24%，从左上延伸至中左区域。将一把陈旧的木质折叠椅置于中心前景，垂直分割构图并部分遮挡人物的躯干与骨盆。相机约置于眼睛高度，朝下倾斜 3–5°。躯干以对角线方向偏离相机，而面部转向镜头方向。人物在低垂厚重的眼睑下直视相机。采用中等拍摄距离，搭配轻度长焦人像镜头透视。避免广角畸变、头部比例过大以及明显的相机倾斜。 姿势：人物坐在椅子后方，身体深深前倾靠在椅背上。肩线向对角下方延伸至右下。一侧手肘紧压在椅背顶部横档上以作支撑，前臂在面部下方横过。另一侧手臂向上弯曲，手掌握住头顶上方的头发。骨盆在椅子后方低位落座。双膝大幅分开并被画面底边裁切。重量自然地通过椅子、支撑手肘和坐骨传递，保持脊柱与手腕的真实对齐关系。 使用一把老式木质折叠椅，带有剥落的白色油漆、深棕色木材、两条横向靠背板以及可见的椅面。大致位置：x23–66，y39–96，占画面约 31%。椅子位于人物前方，遮挡中央躯干与骨盆。姿势锚点：头部中心 x48 y16；抬起的手 x43 y2（被顶边裁切）；接触椅背的手肘 x37 y36；面部下方的手腕 x48 y30；左膝 x16 y76；右膝 x84 y78；双脚均被裁切。景深顺序：前景——椅子与手臂；对焦平面——面部、上身、椅背；中景——分开的双膝；背景——纯净的暖灰色近白影棚墙面。 采用成人编辑级修长轮廓，可见比例约为头部宽度 18%、头部高度 19%、肩部宽度 52%。颈部保持可见，但因前倾折叠姿势而部分受压。保持相对较小的头部、成熟的骨骼结构、修长的前臂、较高的自然腰线与骨盆位置，以及修长的大腿。下半身部分被椅子与裁切遮挡。不得凭空创造未出现的小腿或脚部。若目标图像缺乏身体信息，则使用上述成人比例。不得出现幼态化比例、过大头部、腿部过短，或异常小的手脚。 用来自相机右侧的一束方向性影棚灯照亮场景。最亮区域为面部右侧、鼻梁右侧、上额以及椅子右侧剥落的白色油漆。保留左眼窝、左太阳穴与左下脸周围的深阴影。保持暖米色肤色，搭配冷靛蓝色服装与冷灰棕色阴影。眩光基本为零。保持画面清晰，无明显模糊。不要引入运动模糊、双重边缘、光学失焦或光晕。 曝光表现为空间蒙版效果：x0–30 的墙面保持高调暖近白色；面部左半侧（x39–48）保持阴影；右颧骨与额头（x50–61）接受局部高光。深色服装至少比
