Subject: Vertical lines at the beach. Place the figure large in the center of the frame. On a sunny sand beach, a woman in a white bikini balances her body on one hand and one foot, stretching the opposite leg and arm vertically toward the sky, in a vertical full-body photograph. The body is tilted at a slant, a high-balance pose shown large. Face & expression: her face is angled toward the lower-left of the frame, gaze quietly on the supporting hand. Small oval face, wide-set eyes, thin eyebrows, small nose, pale pink lips. Shoulder-length brown hair with a thin fringe, falling along gravity to the lower-left. Outfit & pose: white thin-strap triangle bikini top and thin white low-rise bottoms. The palm of the lower-left hand and the foot at the lower-right press into the sand, supporting the slanted body. The other leg is extended straight up toward the upper-right of the frame, the opposite arm also extended vertically to the upper-left with the palm open. The hips are lifted high. Background & light: the sea on the left, the sand beach on the right, a green slope behind, with a hard main light from above. Sparkling blue sea and white waves on the left; sandy beach, rocky surface and a dark green slope on the right, with a clear blue sky and few clouds. Strong midday direct sunlight falls on the whole body, casting crisp shadows on the sand. Composition & camera: focus on the figure, keep the full body inside the frame, naturally blur the background. Show the figure large in the center. 4:5 vertical composition, full-body shot from the grounded hand and foot to the upper fingertips and toes without cropping. Place the body's diagonal in the center, splitting the raised arm and leg into the upper-left and upper-right corners. Slightly-below-eye-level wide-angle photograph. Texture & style: photorealistic live-action photography. High-detail realism capturing the natural movement and muscle tone. Clearly render the white swimwear, sand, sea surface, hair and tanned skin texture. Negative: do not break the one-hand one-foot support; do not bend the raised leg.
主题：沙滩的垂直线。
主体：将人物大幅置于画面中央。晴朗的沙滩上，一位身穿白色比基尼的女性以单手单足支撑身体，对侧的腿和手臂垂直向天空伸展，竖版全身照片。身体倾斜，展现大幅度的平衡姿势。
面部与表情：脸朝向画面左下，安静地望向支撑手的方向。小巧鹅蛋脸，横长的眼型，细眉，小巧鼻，淡粉唇。茶色齐肩发配薄刘海，沿重力方向垂向画面左下。
服装・姿势：白色细肩带三角比基尼上装与白色低腰细带下装。画面左下侧的手掌与画面右下侧的脚踩在沙上，将身体斜向撑起。另一条腿笔直向上伸向画面右上，对侧手臂也垂直向画面左上伸展，手掌张开。腰胯高高抬起。
背景・光：画面左侧是海，右侧是沙滩，背景是绿色坡地，上方打下一束生硬的主光。左侧是粼粼碧海与白浪，右侧是沙滩、岩石与深绿坡地，少云蓝天。强烈的正午直射阳光笼罩全身，在沙地上投下清晰的阴影。
构图・相机：焦点对准人物，全身完整入画，背景自然虚化。人物居中放大。4:5竖版构图，从接地的手足到上方手尖与脚尖不裁切的全身镜头。身体的斜线置于画面中央，向上伸展的臂与腿分置左上与右上两角。略低于视线的广角照片。
质感・风格：照片级写实摄影，高精细捕捉动态与肌肉张力的实拍。清晰呈现白色泳装、沙滩、海面、头发与古铜肤色。负向提示词：不要破坏单手单足支撑；不要弯起向上举起的腿。
