关于AI制作广告图片素材起因也是因为公司的设计效率实在太低，得有20天的一个制作周期。所以被迫无奈自己利用AI作图，当然AI做的图肯定不比不上设计做的，但是差距不会太大，可能也就是一些精度有些缺失；多说无益，先看一些AI图片的数据。
以上数据都是AI的图片跑出来的，当然，不是AI的素材就是厉害，厉害的数据是多维度构成的，例如品牌影响力、受众、素材、投放策略、产品、落地页优化等。
一、前置准备
chatGPT、nano banana pro；inageprompt我目前用的这三个已经足够了。Nano banana pro可以看https://zhuanlan.zhihu.com/p/1975133084153316267这个教程自行白嫖。当然有其他的选择也可以，以下步骤我会依据这三个来做演示。
二、Prompt生成
我用ROG键盘为例子做演示
1、prompt反推
在广告资料库里面看同行的素材还不错就丢给inageprompt进行图片prompt反推
得到的prompt可以跟据自己的产品特性和卖点进行修改，这个比较简单。
2、利用chatgpt进行prompt的生成
将自己独立站的产品详情链接给chatgpt，例子：https://rog.asus.com/keyboards/keyboards/aura-rgb/rog-falchion-ace-hfx-zywoo-edition/
https://rog.asus.com/keyboards/keyboards/aura-rgb/rog-falchion-ace-hfx-zywoo-edition/调研该产品的卖点，总结使用场景，基于总结的使用场景生成5个适用于nano banana的文生图prompt，要求图片比例1:1，严格按照上传的图片为主体进行创作，不得有任何细节上的修改。
Chatgpt就会跟据提供的链接去爬取产品卖点和信息，并总结使用场景给出prompt
1、“Futuristic e-sports battlestation at night”
/imagine prompt: the uploaded image of the keyboard at center, placed on a sleek dark e-sports gaming desk illuminated by neon purple and teal RGB ambient lights, subtle fog around the desk, a high-end gaming mouse and dual monitors glowing in the background, cinematic depth-of-field, 1:1
2、“Minimalist compact workspace with stylish keyboard”
/imagine prompt: the uploaded image of the keyboard on a minimalist wooden desk, soft morning sunlight streaming through a window to the right casting gentle shadows, a small potted plant and a notebook beside it, clean air, calm and cozy home office vibe, 1:1
3、“Pro gamer intense FPS match setup”
/imagine prompt: the uploaded image of the keyboard in a close-up, dramatic low-angle shot, warm key-backlight glowing, with blurred fast-motion hands over WASD keys, dynamic motion blur, dark room background with hints of RGB light, esports energy, 1:1
4、“Travel portable desk setup in a cafe”
/imagine prompt: the uploaded image of the keyboard placed on a small café table near a window, soft bokeh cityscape outside, a latte coffee cup next to it, ambient warm café lighting, casual creative traveler / digital-nomad vibe, 1:1
5、“Collector’s showcase with premium gear”
/imagine prompt: the uploaded image of the keyboard centered on a black velvet display platform inside a glass showcase, subtle spotlight from above highlighting its contours, ambient soft ambient RGB glow in background, high-end collector’s presentation, 1:1
尽量使用英文的prompt，不要用中文，因为可能会有些许偏差。其次可以同时连同文案一起写上面也可以，也可以后期自己ps添加文案。
三、nano banana文生图
1、反向prompt
同行原图
Prompt：This is a piece of information about the key, and the product image piece that you put on your feet is a moving piece. The first place on display is the current use of the key to play the electronic game.
If you look down at the camera, you can use the other game settings. In front of the driver’s seat, both hands are on the keyboard, the screen is displayed on the screen, and the first-person shooting game. A box-faced, lacquered key box, a mouse tag, an ornament, and a small bonsai. The background is purple and the light lines are shining brightly, creating a futuristic feeling. Above the text information position, you can quickly touch the key and move it.
Another one wearing a black T-shirt, both hands on the key, and a pair of playing games. Including other items: one red car model, one lost gold plate, and a ten-foot small bonsai tree.
The style of this piece is commercial style, the use is clear, and the style is high-quality. A sense of modern technology and technology. The focus of the image is concentrated on the key, and the unique design and function are strong. The speed and precision of the combination of characters and the combination of words and precision makes it an attractive gamer.
The environment is currently set up, a comprehensive wooden box, a purple background light, and an electronic game shown on the screen. The environmental color of the Wako line is strong, the product has a sense of science and technology, and the sense of the future.
Nano banana生图
2、chatgpt prompt生图
当然也有失败的
这种情况就是数据被污染了，重新开一个对话就可以继续生图。不要想着一次就可以把图片生成好，多抽总会有保底。
