nano banana爆火！网上看到的那些超强效果图是如何生成的呢？谷歌的官方Prompt模板终于来了！赶紧先收藏再说！
这几天爆火的nano banana，让更多人体验到AI对图像生成与处理的革命。
网友们玩疯了，开发出各类好玩的用法。
有用nano banana直接将照片生成手办模型的：
有人脑洞大开，让nano banana、Seedance、Kling联手，将梵高和蒙娜丽莎、戴珍珠耳环的少女等名画的人物，同时带到了今天的纽约中央公园里，开启了一段浪漫的邂逅。
还有人使用nano banana反过来带我们穿越回了中土世界。
视频以第一人称视角在马车上疾驰，穿越迥异的区域，充满了3A游戏大作般的史诗感。
看到网上流传的nano banana生成的以假乱真、脑洞大开的图片和视频，不知道你是否也开始尝试使用nano banana了呢？
同样是生成图片，有人一句话就出大片，有人写满满一屏幕词也不对版。
谷歌为了帮助大家快速上手，亲自下场为我们带来了nano banana官方最强Prompt模板！
甭管你暂时是否理解为什么这样写，先收藏起来试着套模板就对了！
其中的关键是，你要像讲故事一样写场景。
基于nano banana（Gemini 2.5 Flash Image），这6套Prompt模板覆盖了写实、贴纸、文字、产品、留白与分镜，直接套用就能高质量生图！
写实感强的照片，是离不开摄影师的精心巧思的。
要生成写实感强的图像，你得像摄影师一样思考。
你需要考虑机位、镜头类型、光线、细节。
将这些元素加入Prompt后，会引导模型朝更逼真的效果靠近。
即使你不是专业摄影师，只要按照自己的理解多尝试，也大概率会比未说明这些关键要素而直接生成的图片的效果要好。
示例模板：
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.
模板大意：
一张写实风格的[镜头类型]，[主体]，[动作或表情]，场景设定在[环境]。画面由[光线描述]照明，营造出[情绪]氛围。使用[相机/镜头参数]拍摄，突出[关键材质与细节]。图像应为[纵横比]格式。
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.
Prompt大意：
一张写实风格的特写人像：一位日本老陶艺家，脸上被岁月与阳光刻下的深深皱纹，露出温暖而睿智的微笑。他正仔细端详一个刚上釉的茶碗。场景位于他质朴、阳光充足的工作室。柔和的黄金时刻光线自窗外倾泻而入，凸显陶土的细腻纹理。使用85mm人像镜头拍摄，带来柔和的背景虚化（bokeh）。整体氛围宁静而老练。竖版人像构图。
生成的图片：

调用API生图示例Python代码：
from google import genai
from google.genai import types
from PIL import Image
from io import BytesIO
client = genai.Client()
# Generate an image from a text prompt
response = client.models.generate_content(
model=”gemini-2.5-flash-image-preview”,
contents=”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 with pottery wheels and shelves of clay pots in the background. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay and the fabric of his apron. Captured with an 85mm portrait lens, resulting in a soft, blurred background (bokeh). The overall mood is serene and masterful.”,
)
image_parts = [
part.inline_data.data
for part in response.candidates[0].content.parts
if part.inline_data
]
if image_parts:
image = Image.open(BytesIO(image_parts[0]))
image.save(‘photorealistic_example.png’)
image.show()
注意，上述代码需要你在第11行的contents中输入Prompt，在第22行的image.save()中输入你要保存时取的文件名。
后续其他调用API生图的代码仅需要修改这两处即可
在生成贴纸、图标、插图、项目素材这类图片时，你需要先把风格说清楚。
如果有其他特殊需求，比如需要白底的话，你得明确在Prompt中写出。
示例模板：
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 white.
模板大意：
一张[风格]的[主体]贴纸，具有[关键特征]，采用[配色]。设计应当使用[线条风格]与[明暗/上色风格]。背景必须为白色。

nano banana在文本渲染这项任务上的表现是格外瞩目的。
你只需要把文字内容、字体风格（用描述性的词描述）、整体设计说明白，就可以产出质量很好的图片了。
