商业生图与 Prompt 实战指南

想要产出具备商业落地水准的高点击率视觉物料,关键在于掌握**“结构化提示词(Structured Prompt Engineering)”“精准文字渲染控制”**。


1. 商业 Prompt 的黄金五段式公式

主体描述 + 材质与细节 + 光影氛围 + 艺术风格/镜头视角 + 文字渲染要求
  1. 主体明确 (Subject):核心主体是什么、形态、动作、服饰;
  2. 细节与质感 (Details & Texture):表面材质(哑光磨砂、拉丝金属、透明玻璃、丝绸光泽);
  3. 光影环境 (Lighting & Mood):柔和漫反射、伦勃朗光、霓虹赛博朋克、清晨阳光、影棚环形补光;
  4. 镜头与画质 (Camera & Style):商业摄影、85mm 人像定焦、微距特写、电影画质、C4D 3D 渲染;
  5. 文字注入 (Text Rendering):若需要文字直接成画,用英文双引号包裹(针对 gpt-image-2)。

3. 常见生图避坑指南

  • 避免使用模糊的主观形容词:例如“超级好看”、“顶级画质”、“宇宙无敌”。模型更理解“8k octanerender, Hasselblad H6D-100c, soft studio rim lighting”这种具象参数;
  • 💡 巧用文字排版语法:在 gpt-image-2 中,如果需要招牌、书籍封面或易拉罐带有特定英文,请务必用双引号明确圈定,例如 a coffee cup with the text "DAILY FUEL" on the sleeve
  • 💡 多图种子迭代法:遇到满意的构图但细节稍有瑕疵时,固定 Seed(随机种子)或上传该图作为参考底图进行二次重绘(Img2Img),避免每次从头随机抽奖。
