  • 先看效果——乍一看像专业设计师做的完整广告图,不是素材。
  • 核心原理是五层提示词结构,从场景定调到主体描述逐层收窄。
  • 完整提示词先整条给出,再逐层拆解,方便对照着看。
  • 第一层场景定调决定整张图的气质,改这层等于换风格。
  • 五层结构本身是通用的,换生图模型也搬得走。

一条提示词,同时搞定产品摄影和平面设计排版。学完这篇,你也能用 AI 直接生成带标题、品牌元素、UI组件的完整广告图。

先看效果

这张图来自 X 上的创作者 Heisenberg,用 Nano Banana 2 生成。乍一看像专业设计师做的广告:模特穿着绿色连帽衫坐在白色立方体上,画面顶部有大字标题"HOODIE",底部有品牌丝带,侧边还有尺寸选择器和颜色样本。

重点来了:整张图从模特到排版,全部由 AI 一次性生成,没有经过任何后期设计软件。

这种"产品摄影+平面设计"融合提示词,是目前 AI 生图领域最实用的技巧之一。掌握它,你可以快速生成电商主图、品牌广告、社交媒体素材,省掉摄影师和设计师两道工序。

认识 Nano Banana 2

Nano Banana 2 是 Google DeepMind 在 2026 年 2 月发布的图像生成模型(基于 Gemini 3.1 Flash)。它有两个特别适合做广告图的能力:

  1. 文字渲染精准:能在图片里生成清晰可读的英文标题、品牌名、标签文字
  2. 多元素一致性:一张图里同时控制人物、服装、排版、UI元素,不会互相打架

你可以通过 Google AI Studio(aistudio.google.com)免费使用它。

核心原理:五层提示词结构

Heisenberg 的提示词之所以效果好,是因为它把一张广告图拆成了五个层次,每层各管一件事。就像盖房子,地基、墙壁、屋顶、装修、灯光,一层一层搭上去:

第一层:场景定调,告诉 AI "这是一张什么类型的图" 第二层:主体描述,模特长什么样、什么姿势、什么表情 第三层:产品细节,穿什么衣服、什么材质、什么颜色 第四层:平面设计,标题字体、品牌元素、UI组件的位置和样式 第五层:灯光与色调,整体光线、色彩搭配、氛围营造

前三层是传统的"产品摄影提示词",大多数人都会写。第四层和第五层是这个提示词的精华所在:它把平面设计师的工作也交给了 AI。

完整提示词展示

先看原版全貌,再逐层拆解:

英文原文(直接复制使用): Professional commercial fashion advertisement featuring a young male model sitting on a minimalist white matte cube. Neutral, confident expression, looking directly into the camera. Clothing & Styling: Hoodie: A high-quality, heavyweight forest green (British Racing Green) hoodie. It has an oversized fit with a large kangaroo pocket and metal-tipped drawstrings. Bottoms: Clean, slim-fit white trousers with visible seams. Footwear: Stylish low-top sneakers in forest green, navy, and white colorblock design with off-white midsoles and white laces. Accessories: Simple silver bracelet/rings on fingers. Graphic Design & Layout: Typography: The word "HOODIE" is written in a massive, elegant, high-contrast serif font across the top. A small four-pointed yellow sparkle icon is centered inside the "O". Above it, "K A I R O P R E M I U M" is printed in a wide-spaced sans-serif font. Branding Elements: A dark green diagonal "caution-tape" style ribbon runs across the bottom third, with repeating white all-caps text reading "PREMIUM HOODIE". UI Element Accents: A yellow pill-shaped size selector labeled "S M L XL" on the left side. A small thumbnail depicting the hoodie floats at the left-center. Three circular color swatches (green, yellow, black) on the right side. Two justified blocks of serif body text describing product comfort and eco-friendly materials. Website URL "www.kairofashion.com" at the bottom-left. Environment & Lighting: Setting: A clean, bright, white-on-white minimalist studio cove. Lighting: Soft, diffused studio lighting casting gentle shadows beneath the model and cube, highlighting the rich texture of the green fabric and the crispness of the white trousers. Color Palette: Deep forest green, bright white, and golden yellow accents. 中文对照(帮助理解): 专业商业时尚广告,主角是一位年轻男性模特,坐在极简的白色哑光立方体上。表情中性、自信,直视镜头。 服装与造型: 连帽衫:高品质重磅森林绿(赛车绿)连帽衫,宽松版型,大号袋鼠口袋,金属尖端抽绳。 下装:干净的修身白色长裤,可见接缝。 鞋履:时髦低帮运动鞋,森林绿/海军蓝/白色拼色,灰白中底,白色鞋带。 配饰:手指上佩戴简单银色手镯/戒指。 平面设计与布局: 字体排版:"HOODIE"以巨大的高对比度衬线字体写在顶部。一个四角黄色火花图标居中在"O"内部。上方用宽间距无衬线字体印有"K A I R O P R E M I U M"。 品牌元素:深绿色对角线"警示带"风格丝带横跨底部三分之一,重复印有白色全大写"PREMIUM HOODIE"。 UI元素点缀:左侧黄色药丸状尺寸选择器"S M L XL";左中位置连帽衫缩略图;右侧三个圆形颜色样本(绿、黄、黑);两块衬线正文描述产品舒适度和环保材料;左下角网址。 环境与灯光: 干净明亮的白色极简影棚。柔和漫射灯光,模特和立方体下方投出柔和阴影,突出绿色面料质感和白色裤子的挺括感。 色调:深森林绿、亮白色、金色黄色点缀。

逐层拆解

第一层:场景定调

Professional commercial fashion advertisement featuring...
(专业商业时尚广告,主角是...)

这一句话定了整张图的"基因"。AI 看到"professional commercial fashion advertisement",会自动调用商业广告的视觉风格:干净背景、专业打光、高质感呈现。

换成别的关键词,整张图的风格就完全不同:

  • editorial fashion spread → 杂志内页风
  • streetwear lookbook → 街拍目录风
  • luxury brand campaign → 奢侈品大片风

第二层:主体描述

young male model sitting on a minimalist white matte cube.
Neutral, confident expression, looking directly into the camera.

三个要素:人物特征(年轻男性)、姿势(坐在白色立方体上)、表情(中性自信、直视镜头)。

"坐在白色立方体上"这个细节很聪明。白色立方体是广告摄影里常用的道具,它既能让模特有一个自然的坐姿支撑,又不会抢产品的视觉焦点。

第三层:产品细节

这是篇幅最大的部分,分成了四个小类:连帽衫、裤子、鞋、配饰。

关键技巧是用具体的形容词替代笼统描述:

  • 不说"绿色连帽衫",说"高品质重磅森林绿(赛车绿)连帽衫"
  • 不说"白色裤子",说"干净的修身白色长裤,带有可见接缝"
  • 不说"运动鞋",说"森林绿/海军蓝/白色拼色低帮运动鞋,灰白中底"

越具体,AI 越不容易"自由发挥"出你不想要的东西。

第四层:平面设计(核心亮点)

这一层是整条提示词最有价值的部分。它告诉 AI 在照片上面叠加平面设计元素:

写平面设计层的要点:明确位置、明确样式、明确内容。不要只说"加一个标题",要说"在顶部用巨大的衬线字体写HOODIE"。

第五层:灯光与色调

Soft, diffused studio lighting casting gentle shadows...
Color Palette: Deep forest green, bright white, and golden yellow accents.

"柔和漫射灯光"是商业广告的标配。明确写出色调(深绿+亮白+金黄),能让 AI 把所有元素统一在一个和谐的配色方案里。

变量替换表

掌握了五层结构,你可以替换任何变量来生成不同的广告图:

从零开始操作指南

  1. 打开 Google AI Studio:访问 aistudio.google.com,用 Google 账号登录
  2. 选择模型:在左侧面板选择 Gemini 3.1 Flash(也就是 Nano Banana 2),确保开启了图像生成功能
  3. 输入提示词:把上面任意一个英文提示词完整复制粘贴到输入框。不要翻译成中文,Nano Banana 2 对英文提示词的理解最准确
  4. 生成图片:点击发送,等待 10-30 秒。Nano Banana 2 会一次性生成包含摄影和平面设计元素的完整广告图
  5. 检查结果:重点看三件事:
  6. 文字是否清晰可读(标题、品牌名、丝带文字)
  7. UI元素是否在正确位置(尺寸选择器在左、颜色样本在右)
  8. 整体配色是否统一
  9. 微调重试:如果文字渲染不理想,可以在提示词开头加上 Ultra-high quality text rendering.;如果布局不对,把位置描述写得更具体(比如"top-left corner"改为"positioned at the upper-left, 10% from the edge")
  10. 保存下载:右键图片保存,或点击下载按钮。建议保存为 PNG 格式以保留文字细节

小互说: 以前做一张像样的产品广告图,至少要三个人配合:摄影师拍产品、设计师做排版、甲方反复改稿。现在一条结构清晰的提示词就能搞定大部分工作。关键是掌握"五层结构"的思路:先定调、再描主体、写产品细节、加平面设计、收灯光色调。你觉得这种"一条提示词出整张广告"的方式,会怎样改变设计行业?
