造梦师手记：Stable Diffusion胶片级画质模型
在我的怂恿下，正在读博的朋友给实验室的电脑加了一块3060，开始玩Stable Diffusion。搞科研很辛苦，AI绘图是很好的放松方式。
不过，朋友最近又买了一个拍立得，没事把身边的花花草草拍下来。
和拍立得相比，AI绘画有一个小缺点：精美的画面里，缺乏一丝丝真实感。
主要原因是训练用的素材大多是精修过的美女照片，本身就是失真的。
好在有人用尽可能更加“真实”的素材训练了一些模型，可以画出接近照片的画质。我曾经介绍过几个光影和画质方面都接近真实的微调模型，今天给大家介绍一个从源头上解决的大模型：MoonFilm
作者在介绍这个模型的时候称：
这是一个用于生成写实风格 AI 照片的 checkpoint 大模型，其前身是我在 C 站发布的 MoonMIX系列大模型。新版本MoonFilm是使用扩容后的FilmGirl胶片风 LoRA图像训练集，使用 Dreambooth 训练而成的微调大模型。其人像真实感显著提升，如果你非常追求 AI 照片的真实质感，请务必尝试下这个大模型！
同时推荐搭配TEXTUAL INVERSION模型：bad_pictures、negative_hand Negative Embedding。这两个Negative Embedding模型在不显著影响图像质感的同时，可以很好地起到图像修正优化效果。
下面让我们试一试这个模型到底有多“真实”。
1、光，影，女孩
提示词：
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.负面提示词：
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 不难发现，真实感主要来自于光影。
2、落日、水边、穿牛仔短裤的女孩
提示词：
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，阳光，女孩
提示词：
Best portrait photography, 35mm film, natural blurry, 1girl, sun dress, wide brimmed hat, radiant complexion, whimsical pose, fluttering hair, golden sunlight, macro shot, shallow depth of field, bokeh, dreamy. 4、赛博城市的跑车
提示词：
yper realistic,metal,professional photo of a futuristic muscle car with multiple modifications, large wheels, driving, cybernetic hood, cyber car parts, front pop up headlights, science fiction, sci-fi scenario, (night), natural light, cyberpunk, futuristic city, cyberpunk city, neon signs, highly detailed, (highly detailed background), multiple buildings in the background, detailed textures, wide angle, 8k, HDR, professional photoshoot, high quality photo, realistic photo, realistic shadows, detailed shadows, realistic proportions,film grain, raw photo,(front).5、混用lora
lolita，权重0.4
提示词：
1girl, (flowers=1.5), Issuing, plant,sunlight, outdoors, white dress, long hair,((Cinematic Lighting)), hair between eyes, .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.模型下载：
