提示词
英文：Macro photography of a black smart wristband (focus on a partial close – up), statically placed against a pure gray background. Dramatic, high – contrast light hits the wristband, highlighting the sleek metallic strip with sharp reflections, the textured pattern on the black rubber band, and the crisp display details (emphasizing the visual effect without text). The light creates strong shadows around the wristband, enhancing the sense of depth and the technological texture of the materials, making the smooth metal and matte rubber contrast sharply.
中文：微距摄影展示一只黑色智能手环（聚焦局部特写），静态置于纯灰色背景前。富有戏剧性的高对比度光线照射在手环上，凸显带有锐利反光的光滑金属条、黑色橡胶带的纹理图案，以及清晰的显示细节（强调视觉效果，无文字）。光线在手环周围营造出强烈阴影，增强了深度感与材质的科技质感，使光滑金属与哑光橡胶形成鲜明对比。
