stable diffusion工具、插件基本都会用后，还是无法生成自己喜欢的图，你会发现提示词的话不会说，也没法友好的使用~

比较通用的正向提示词：

词缀的权重默认值都是1，从左到右依次减弱，权重会影响画面生成结果。比如景色Tag在前，人物就会小，相反的人物会变大或半身。选择正确的顺序、语法来使用提示词，将更好、更快、更有效率地展现所想所愿的画面。

最好的质量，超详细，杰作，精细的细节，高分辨率，8k 壁纸

best quality, ultra-detailed, masterpiece, finely detail, highres, 8k wallpaper

也有些常用的反向提示词，这些是图片不好的描述词

注意：

NSFW 不适合在工作时看的内容，包括限制级，还有低画质相关和一些容易变形身体部位的描述等。注：可下载 Easynegative 的文件，它已把一些常用的反向提示词整合在一起了，我们只需输入关键词就能得到较好效果。把它放到 /enbeddings 文件夹，需要触发时在反向提示词中输入easynegative 激活。

AI 会依照概率来选择性执行，如提示词之间有冲突，AI 会根据权重确定的概率来随机选择执行哪个提示词。生成图片的大小会影响 Prompt 的效果，图片越大需要的 Prompt 越多，不然 Prompt 会相互污染。Prompt 支持使用 emoji，且表现力较好，可通过添加 emoji 图来达到效果。如形容喜欢表情，可修手。

为了便于理解，不相关词缀可以用换行以示区分。

本文主要是学习词缀变化带来的出图变化，不同模型生图不同，学习时需观察同模型下的出图变化。以下为主要参数参考，学习时设置个负面词，其余默认即可。
