最近，相信大家的朋友圈和社交媒体都被一个叫nano banana的AI图像生成工具刷屏了。从精致的手办模型到名画人物穿越，再到中土世界场景还原，nano banana已然成为了最火爆的"整活工具之一。
刚刚，谷歌为nano banana推出了官方Prompt模板，包含写实、贴纸、文字、产品、留白与分镜六大场景。每个模板都配有详细示例，让我们能够轻松套用，生成高质量图片。
nano banana作为谷歌的AI图像生成工具，近期带来的创作热潮让我们看到了AI创作的无限可能。而官方Prompt模板的发布，让这个工具变得更加易用，输出效果也更加稳定。
六个超实用的场景模板
1. 写实摄影
运用写实模板，需要详细描述机位、镜头、光线等要素，可以让我们像摄影师一样思考。比如想要生成一张照片级的特写肖像，就需要描述主体表情、环境光线、镜头型号和画面比例，这样才能获得逼真的图像效果。
官方模板：
A photorealistic shot type of subject, action or expression, set in environment. The scene is illuminated by lighting description, creating a mood atmosphere. Captured with a camera/lens details, emphasizing key textures and details. The image should be in a aspect ratio format.
示例Prompt：
A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile. He is carefully inspecting a freshly glazed tea bowl. The setting is his rustic, sun-drenched workshop. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay. Captured with an 85mm portrait lens, resulting in a soft, blurred background (bokeh). The overall mood is serene and masterful. Vertical portrait orientation.

2. 风格化插画和贴纸
贴纸模板则需要明确风格和背景要求。想要创建贴纸、图标或设计素材，应当说明所需的风格，并指定白色背景。示例中展示了如何生成一个卡哇伊风格的小熊猫贴纸，包括轮廓线、着色方式和色彩搭配等细节。
官方模板：
A style sticker of a subject, featuring key characteristics and a color palette. The design should have line style and shading style. The background must be transparent.
示例Prompt：

3. 文本渲染
文字渲染模板则要说明字体风格和设计需求。产品拍摄模板强调商业感，建议使用干净背景和可控布光，适合电子商务和广告用途。留白设计模板适合制作网站背景和简约风格设计。分镜模板可用于创作漫画和故事板，为内容创作者提供便利。
官方模板：
Create a image type for brand/concept with the text "text to render"in a font style. The design should be style description, with acolor scheme.
示例Prompt：

**6. 漫画分格 /**故事板
分镜模板可用于创作漫画和故事板，为内容创作者提供便利。

除了官网提示词模板，谷歌还提供了调用API生图的Python代码示例。
通过谷歌发布的提示词指南，可以看到描述场景而非罗列关键词是nano banana的核心使用原则。与一堆零散的关键词相比，一段叙事性的、富有描述力的段落更容易生成优质、连贯的图像。
有效的Prompt需要包含足够的上下文和具体指示。提供拍摄类型、主体描述、动作表情、环境设置、光线描述、氛围营造、相机镜头细节、关键纹理和细节以及宽高比格式等信息，能够引导模型创造出照片级的效果。
这些模板不仅让普通用户更容易上手，也为专业创作者提供了标准化工作流程。通过多轮对话逐步优化图像，进行微调直至完美，这个功能特别适合需要精细调整的商业项目。
目前，大家可以通过Google AI Studio进行体验或通过官方文档中的代码进行调用。
随着AI图像生成技术的不断成熟，提示工程的重要性越来越明显。谷歌这次发布的官方模板，不仅提供了实用工具，也为整个行业的提示词设计提供了很好的参考。
