Stable Diffusion入门使用技巧及个人实例分享

大家好,我是小鱼姐姐,近期使用Stable Diffusion比较多,积累整理了一些内容,得空分享给大家。如果你近期正好在关注AI绘画领域,可以看看哦。

本文不包含SD如何安装及使用的内容,比较适合已经解决了安装问题,在寻找合适的大模型及lora,或者想找一些绘画案例给自己的创作带来一些灵感的人。文章总共2000多字,且涉及大量图片,谨慎观看哈。下面正式开始。

Stable Diffusion简介

Stable Diffusion 是由CompVis、Stability AI和LAION共同开发的一个文本转图像模型,它通过LAION-5B子集大量的 512x512 图文模型进行训练,我们只要简单的输入一段文本,Stable Diffusion 就可以迅速将其转换为图像,同样我们也可以置入图片或视频,配合文本对其进行处理。

通俗的解释:

StableDiffusion是一种基于扩散过程的图像生成模型,可以生成高质量、高分辨率的图像。它通过模拟扩散过程,将噪声图像逐渐转化为目标图像。这种模型具有较强的稳定性和可控性,可以生成具有多样化效果和良好视觉效果的图像。

下面推荐几个我在C站挖掘的目前最常用的几个模型:1、好看人物插画风:

说明:

https://civitai.com/models/1540/unstableinkdream?modelVersionId=40626

优点:画人物特别好看

建议搭配参数: 采样器:DPM++ 2M Karras 步数20

绘画示例:

1、人物角色设计:

提示词示例:((masterpiece)),((nsanely detailed)), ((intricate)),((high quality)) a little girl character, pop-art illustration style, simple,cute, 5 years old girl, full color,  blue dress, blue shoes, long brown hair, blue hat, no outline,  3d

基于这个人物尝试制作一个4格漫画:

2、生成类似的背景+不同的人物:

提示词示例:((masterpiece)),((nsanely detailed)),  ((HD Quality)),((exquisite face))

background: The background is a construction site, with skyscrapers under construction,  feeling in 1990s shenzhen.

character:There is only one 20-year-old smile asian female agent,must appear item:balloon

关于这个模型的一个小技巧:

这个模型其他都好,就是你们看我上面生成的图片人物都很精致很好看,但是就是颜色一直是灰蒙蒙的效果。多方查阅之后,找到一个方法,需要下载一个VAE,然后在设置里面勾选上即可:

2、生成故事插画:

((masterpiece)),((nsanely detailed)), ((intricate)),Best quality,anime,Draw a little girl  [Zhang Ziyi | Lin Chiling] walking in the park, wearing a beautiful red dress, she showed a surprised expression,suddenly only a cute white kitten in the grass.

((masterpiece)),((nsanely detailed)), ((intricate)),((high quality))  5 years old standing girl,  simple,cute, full color, brown hair, yellow dress, black shoes.She stands in a magical garden surrounded by  colored flowers . Her big eyes were full of curiosity and surprise.

3、超真实风格

说明:

https://civitai.com/models/4823/deliberate

使用较多,默认真实风格,且搭配很多lora效果都不错

建议搭配参数:DPM++ SDE Karras+step20

绘画示例:

1、生成类似的背景+不同的人物:

绘画提示词:((masterpiece)),((nsanely detailed)), ((HD Quality)),((exquisite face))

background: The background is a construction site, ((skyscrapers under construction)),  feeling in 1990s shenzhen china.

character:There is only one asian female agent,clear face,20-year-old,smile,must appear item:(an ice cream cone)

同样的提示词,加上lora之后,表情质感确实更好一点点

4、动画:

5、悬疑风/风景/插画

LORA

LoRA模型全称是:Low-Rank Adaptation of Large Language Models,通俗的可以理解为Stable-Diffusion中的一个插件,仅需要少量的数据就可以进行训练的一种模型。在生成图片时,LoRA模型会与大模型结合使用,从而实现对输出图片结果的调整。
