完整提示词
matte green tea can with minimal japanese typography, suspended mid-air with floating tea leaves and frozen condensation droplets, soft top-down studio light, low contrast, centered composition with bottom third negative space, glass refraction and water droplet detail, ultra sharp edges, clean white background, commercial product photography, no extra text --ar 4:5 --v 6 --s 250
结构拆解
这条提示词最关键的设计是用悬浮+冰镇暗示喝感。floating tea leaves 和 frozen condensation 让观众脑补"冰凉清爽"，比直接写"refreshing"或"cold"具体得多。留白方向 bottom third 给文案预留版位。
3 种改写版本
frosted glass serum bottle with golden dropper cap, suspended mid-air with scattered rose petals and small water droplets, soft side studio light from the left, low contrast, centered composition with bottom third negative space, glass refraction and dewy detail, ultra sharp edges, blush pink seamless background, commercial product photography, no extra text --ar 4:5 --v 6 --s 300
把绿茶罐换成精华液瓶，茶叶换成玫瑰花瓣，白底换成腮红粉底。骨架不动，三处替换完成品类切换。
brushed titanium smartwatch suspended mid-air, soft micro reflections, single hard light from above-left, matte black background with faint vertical gradient, centered composition with 80% negative space, sub-millimeter brushed grain visible, ultra sharp edges, cinematic dark color grading --ar 16:9 --v 6 --s 400
改成暗调奢品风：单一硬光、深色背景、80% 留白、亚毫米级材质细节。--s 拉到 400 强化氛围。
glossy chocolate croissant suspended mid-air with cascading molten chocolate, golden flaky layers with visible butter sheen, soft warm side light from the right, shallow depth of field, centered composition with right third negative space, rich brown and cream palette, food magazine cover style --ar 4:5 --v 6 --s 250
食品广告核心是暖光+饱满高光+一个流动动作（cascading）。留白改到右侧 1/3 方便加标题。
常见翻车点
多数模型会在罐身写一段乱码英文。务必加 "no extra text" 或 Midjourney --no text。
不写背景，模型会塞树叶、流水、城市夜景一类装饰。必须显式写 "clean white background"、"matte black background" 等。
"soft light + warm light + rim light + golden hour"叠在一起会让光位失控。一条产品图通常只写 1 个主光位。
"with negative space" 太笼统。明确写 "bottom third negative space" 或 "right third for headline"。
"高级感"分极简（白/灰/克制）和重质感（深底/单光/特写）两个流派。任意一个都比"高级"具体。
"premium material" 不起作用。改成 "brushed titanium / frosted glass / matte ceramic"等具体材质名。

适用场景
这条骨架适合所有"单品+干净背景+商业感"的产品图：饮料、化妆品、数码、奢侈品、食品、香水。如果是服饰，建议改成 flatlay（平铺）骨架；如果是大件家电，建议改成场景化骨架（室内 + 自然光）。
