网上流传着一条一千五百字的提示词，审美非常好——可以把照片变成独立杂志封面：上半张是原封不动的照片，下半张是手绘的小插画，凑一起像本独立出版物。

全篇一千五百字，比不少文章都长。但为什么这么长的提示词反而比 15 个字的好用？

为什么形容词不如数字和边界有用

这条提示词的关键特点是用精确的数字和明确的边界替代了模糊的形容词。比如"严格 3:4 竖版构图""画面水平分为两个完全相等的部分，精确 1:1 高度比"。数字替模型做决定——你说"上下两部分"，模型还得猜比例是多少；写 1:1，它就不用猜了。提示词里每让模型猜一次，就多一次跑偏的机会。

用边界管住模型的手

很多时候模型翻车，毛病出在没说清哪些东西不能碰。你写了"艺术化""风格化"，模型为了讨好你，转头就把人脸改了。先把红线划上，等于给后面所有风格要求套了个笼子。调色可以，加纹理可以，笼子里的别动。

提示词里"不许动"那部分应该比"想要什么"写得更啰嗦。想要什么模型自己会发挥，不许动什么你不说它就一定动。这条提示词同时禁了"纯线稿"和"复杂写实插画"——一边不能简单到只剩线，一边不能复杂到接近写实。两条边界往中间一夹，剩下那条窄缝才是它要的东西。

完整提示词

这条 1500 字提示词的核心结构：

• 精确的数字比例：3:4 构图、1:1 分割，不让模型猜
• 明确的不许动清单：保持主体构图、面部特征、身体比例、姿势表情不变
• 克制的风格修饰："subtle""sophisticated"限定调色深度
• 两边边界夹击：禁纯线稿 + 禁复杂写实，锁定中间风格区间
• 可验证的结果标准：违反了能不能看出来？形容词说不清，数字和边界能
