造夢(mèng)師手記：Stable Diffusion膠片級(jí)畫(huà)質(zhì)模型
在我的慫恿下，正在讀博的朋友給實(shí)驗(yàn)室的電腦加了一塊3060，開(kāi)始玩Stable Diffusion。搞科研很辛苦，AI繪圖是很好的放松方式。
不過(guò)，朋友最近又買(mǎi)了一個(gè)拍立得，沒(méi)事把身邊的花花草草拍下來(lái)。
和拍立得相比，AI繪畫(huà)有一個(gè)小缺點(diǎn)：精美的畫(huà)面里，缺乏一絲絲真實(shí)感。
主要原因是訓(xùn)練用的素材大多是精修過(guò)的美女照片，本身就是失真的。
好在有人用盡可能更加“真實(shí)”的素材訓(xùn)練了一些模型，可以畫(huà)出接近照片的畫(huà)質(zhì)。我曾經(jīng)介紹過(guò)幾個(gè)光影和畫(huà)質(zhì)方面都接近真實(shí)的微調(diào)模型，今天給大家介紹一個(gè)從源頭上解決的大模型：MoonFilm
作者在介紹這個(gè)模型的時(shí)候稱(chēng)：
這是一個(gè)用于生成寫(xiě)實(shí)風(fēng)格 AI 照片的 checkpoint 大模型，其前身是我在 C 站發(fā)布的 MoonMIX系列大模型。新版本MoonFilm是使用擴(kuò)容后的FilmGirl膠片風(fēng) LoRA圖像訓(xùn)練集，使用 Dreambooth 訓(xùn)練而成的微調(diào)大模型。其人像真實(shí)感顯著提升，如果你非常追求 AI 照片的真實(shí)質(zhì)感，請(qǐng)務(wù)必嘗試下這個(gè)大模型！
同時(shí)推薦搭配TEXTUAL INVERSION模型：bad_pictures、negative_hand Negative Embedding。這兩個(gè)Negative Embedding模型在不顯著影響圖像質(zhì)感的同時(shí)，可以很好地起到圖像修正優(yōu)化效果。
下面讓我們?cè)囈辉囘@個(gè)模型到底有多“真實(shí)”。
1、光，影，女孩
提示詞：
1girl, Floral motifs,long hair, luminous skin, enchanting gaze, embellished attire, natural lighting,.shallow depth of field, romantic setting, dreamy pastel palette, whimsical details, captured on film，. (RAW photo, best quality),(realistic, photo-realistic:1.3), clean, masterpiece,finely detail,masterpiece,ultra-detailed,highres,(best illustration),(best shadow),intricate, bright light.負(fù)面提示詞：
nsfw,logo,text,badhandv4,EasyNegative,ng_deepnegative_v1_75t,rev2-badprompt,verybadimagenegative_v1.3,negative_hand-neg,mutated hands and fingers,poorly drawn face,extra limb,missing limb,disconnected limbs,malformed hands,ugly 
不難發(fā)現(xiàn)，真實(shí)感主要來(lái)自于光影。
2、落日、水邊、穿牛仔短褲的女孩
提示詞：
A young woman stands on a weathered wooden dock extending over a still mountain lake at dusk. Dressed in cutoff denim shorts and a loose white tank top, she gazes pensively over the glassy waters with hands in her pockets. Her long honey-blonde hair glows in the golden light of the setting sun. A sense of peace and solitude pervades this high alpine scene at day's end as the sky fades into pastel hues and the loons begin their plaintive calls.
3、草帽，陽(yáng)光，女孩
提示詞：
