蓝盘钢表平躺在浅灰石板上
中画幅静物：100mm f/11，一盏顶部柔光箱，深蓝表盘是唯一色彩。
✍️ 灯位清单写得完整：顶部大柔光箱、右侧白卡、接触阴影，三件事就把钢的质感立住了。禁文字那一句其实最关键，生成模型最爱在表盘上乱写字，提前堵住才能得到干净的表面。

Square 1:1 frame, centred, with room to breathe on all sides. On a slab of pale grey stone lies a classic steel wristwatch, dark blue dial, slim hands and plain baton hour markers, flat on its back while the steel bracelet and its polished bezel and brushed case curve gently around it.
Make it read as a genuine photo of the commercial still-life kind: medium-format digital sensor, 100mm lens, f/11 for deep, crisp focus from edge to edge, ultrafine grain.
One big softbox sits overhead, shifted a little to the front-left, giving the polished bezel clean specular accents and sweeping soft light over the brushed case and sapphire crystal. On the right a small white card opens up the shadows, and a short contact shadow tucks under the bracelet. Grade it cool and neutral with tight tonal separation; the deep midnight blue dial is the only colour accent.
Exclude people, hands, legible text, numerals, logos, brand marks and labels from every object. Surfaces stay plain.

商业静物，按真实照片的方式拍摄：中画幅数码传感器，100mm 镜头，光圈 f/11，所以景深很深、画面从边到边都清晰，颗粒极细。主体是一块经典钢壳腕表，深蓝表盘、简洁的条形时标和纤细指针，平放在一块浅灰色石板上。拉丝表壳、抛光表圈和钢制表链顺势微微弯曲，整体居中摆在方形画幅里。
布光：一盏大型顶置柔光箱，略偏向左前方，在抛光表圈上打出干净的高光点，并在拉丝表壳与蓝宝石表镜上扫过一层柔和的光。右侧放一张小白卡提亮阴影，表链下方有一道很短的接触阴影。色调冷中性，影调层次收紧，深午夜蓝的表盘是画面里唯一的色彩点缀。
构图：方形 1:1，居中，四周留出呼吸空间。画面里不要出现人物、手、可读文字、数字、标志、品牌标记和标签，所有表面保持素净。
