Blue bar in the gym • Sports moments in window light

Subject: In the center of a bright gym, an adult woman sitting on a lat pulldown machine, pulling a blue curved bar down to her chest with both hands, a vertical photo.

Figure/Expression: Face slightly tilted upwards and towards the right side of the frame, gaze also directed to the upper right. Focused expression with a closed mouth. Smooth oval silhouette, natural eyebrows, horizontally long brown eyes, small nose, light pink lips. Dark brown hair tied into a high round bun, with thin bangs and wisps at the temples.

Attire/Pose: Light aqua blue camisole sports top, with fine ruching at the center of the chest, black short drawstring sports shorts. Sitting facing the machine, back straight, arms spread upwards to the left and right, pulling the bar down to the upper chest position.

Background/Lighting: Soft daylight streams in from the large window on the left side of the frame, brightly illuminating the left silhouette of the figure. Grey training equipment and cables are arranged in the background, softly blurred with shallow depth of field.

Composition/Camera: 3:4 vertical composition, a slightly front-facing waist-up portrait, slightly lower than the figure's eye level. The figure is centered and enlarged, with the blue bar curving down from above to the chest, and the arms not cropped at the edge of the frame. Focus is on the face and upper body, with natural bokeh in the background.

Texture/Style: Realistic live-action photo. Finely depicts the natural texture of the skin, the stretchiness of sports fabric, the blue coating of the metal bar, and the soft shadows from the window light.

Avoid: Not changing the shape and grip of the bar; not letting the hair down.

主體： 明亮健身房的畫面中央，一位成年女性坐在滑輪下拉機上，雙手大幅握住藍色曲線拉桿並下拉至胸前的瞬間，縱向照片。

人物・表情： 臉部略微上揚並朝向畫面右方，視線也看向右上。閉著嘴的專注表情。平緩的卵形輪廓，自然的眉毛，橫長的棕色眼睛，小巧的鼻子，淡粉色的嘴唇。深棕色頭髮綁成高高的圓髮髻，有薄劉海與鬢角的碎髮。

服裝・姿勢： 淡水藍色的細肩帶運動上衣，胸前中央有細密的抽褶，黑色短版抽繩運動褲。正面朝向機器坐下，背脊挺直，雙臂向左右上方張開，將拉桿拉到上胸位置。

背景・光線： 畫面左方的大窗射入柔和的日光，明亮地照出人物的左側輪廓。背景配置灰色的訓練機具與鋼索，以淺景深柔和地模糊。

構圖・鏡頭： 3:4 的縱向構圖，比人物視線略低的偏正面腰上肖像。人物置於中央並放大，藍色拉桿從上方呈弧線收進胸前，手臂不在畫面邊緣被裁切。焦點在臉部與上半身，背景自然散景。

質感・風格： 寫實的實拍照片。精細描繪肌膚的自然紋理、運動布料的伸縮感、金屬桿的藍色塗裝、窗光的柔和陰影。

負面提示： 不要改變拉桿的形狀與握法；不要把頭髮放下來。
