市面上ai繪畫軟件我也試用過不下十款了，但是最終最強的，泛用性好的還是Stable Diffusion和Midjourney，他們兩個對比之下有什么優(yōu)缺點呢？

Midjourney是要付費的，30美金一個月約等于216塊錢，只有15小時快速出圖時間，對一部人來說是一比不小的開支

注意事項

·1.安裝路徑盡量不要有中文安裝路徑，即你放置stable DiffusionWebUI的文件夾及它所屬的文件夾，任何一層文件夾里有中文都會導(dǎo)致一些路徑索引的過程報錯

2.webUI文件夾放在較空的盤AI繪畫需要下載并運用大量模型文件模型數(shù)量多了以后是很占地方的，盡量不要將其堆積在C盤之類的系統(tǒng)盤

標(biāo)簽器只能識別大概的關(guān)鍵詞內(nèi)容，描述的不準(zhǔn)確的地方自己再修改一下

同樣的辦法，關(guān)鍵詞：A girl walking in a city street, high rise, mechanical city, cyberpunk, raining, facing the audience, wearing fashion, jackets

一個女孩走在城市的街道上，高樓大廈，機械城市，賽博朋克，下雨，面對觀眾，穿著時尚，夾克衫

局部重繪：發(fā)送到圖生圖，再發(fā)送到局部重繪，使用上一次的關(guān)鍵詞和種子

如果想改背景和不想改人臉就涂抹一下，充當(dāng)蒙版，選擇重繪非蒙版內(nèi)容

如果只想改臉就選擇重繪蒙版內(nèi)容

如果只想換背景人物和衣服都不變，就把整個人物涂抹一下，重非蒙版內(nèi)容

萬金油關(guān)鍵詞：

正面提示詞后添加：

?(Masterpiece: 1,2), best quality, masterpiece, high definition, original, extremely detailed wallpaper, soft light

負(fù)面提示詞后添加：

NSFW, (worst quality:2), (low quality:2), (normal quality:2), lowres, normal quality, ((monochrome)), ((grayscale)), skin spots, acnes, skin blemishes, age spot, (ugly:1.331), (duplicate:1.331), (morbid:1.21), (mutilated:1.21), (tranny:1.331), mutated hands, (poorly drawn hands:1.5), blurry, (bad anatomy:1.21), (bad proportions:1.331), extra limbs, (disfigured:1.331), (missing arms:1.331), (extra legs:1.331), (fused fingers:1.61051), (too many fingers:1.61051), (unclear eyes:1.331), lowers, bad hands, missing fingers, extra digit,bad hands, missing fingers, (((extra arms and legs))),

之后根據(jù)自己積累的經(jīng)驗，熟悉應(yīng)用插件，手繪修改不合理的地方就行了

ai繪畫的最大的問題就是畫不好手，腳趾，這些復(fù)雜結(jié)構(gòu)
