本文将详细介绍如何使用StableDiffusion生成逼真的人物图像。

首先选择DMP++ 2M Karras 采样器，采样步数调整到20。

然后输入提示Prompt: photo of young woman, highlight hair, sitting outside restaurant, wearing dress
年轻女子的照片，头发染成亮色，坐在餐厅外面，穿着裙子。

当我们自己尝试的时候，往往是这种结果，是哪里出了问题

负面提示「Negative prompt」

让我们添加一个负面提示。这个负面提示非常简约。它旨在产生更好的解剖学并远离非现实主义风格。
Negative prompt：disfigured, ugly, bad, immature, cartoon, anime, 3d, painting, b&w
加入负面提示看下效果：

效果好了一点，但还是有提升空间

添加灯光照明关键词

提示词语改成：photo of young woman, highlight hair, sitting outside restaurant, wearing dress, rim lighting, studio lighting, looking at the camera

质感有了很大的提升

添加相机关键词

像数码单反相机、超高画质、8K、UHD等关键词可以提高图像的质量。
提示改成：photo of young woman, highlight hair, sitting outside restaurant, wearing dress, rim lighting, studio lighting, looking at the camera, dslr, ultra quality, sharp focus, tack sharp, dof, film grain, Fujifilm XT3, crystal clear, 8K UHD

可能有那么点提升，虽然不是很明显

添加面部细节

最后，一些关键词可以用作描述眼睛和皮肤的。这些关键词旨在呈现更真实的面孔。

1. highly detailed glossy eyes「高度详细的光泽眼睛」
2. high detailed skin「高度详细的皮肤」
3. skin pores「皮肤毛孔」

使用这些关键词的一个副作用是将主题拉近镜头。
提示改成：photo of young woman, highlight hair, sitting outside restaurant, wearing dress, rim lighting, studio lighting, looking at the camera, dslr, ultra quality, sharp focus, tack sharp, dof, film grain, Fujifilm XT3, crystal clear, 8K UHD, highly detailed glossy eyes, high detailed skin, skin pores

控制面孔

提示改成：photo of young woman, [Ana de Armas:Emma Watson:0.5], highlight hair, sitting outside restaurant, wearing dress, rim lighting, studio lighting, looking at the camera, dslr, ultra quality, sharp focus, tack sharp, dof, film grain, Fujifilm XT3, crystal clear, 8K UHD, highly detailed glossy eyes, high detailed skin, skin pores
两人脸部叠加效果
但是这个构图就可能会受到影响。
提示改成：photo of young [woman:Ana de Armas:0.4], highlight hair, sitting outside restaurant, wearing dress, rim lighting, studio lighting, looking at the camera, dslr, ultra quality, sharp focus, tack sharp, dof, film grain, Fujifilm XT3, crystal clear, 8K UHD, highly detailed glossy eyes, high detailed skin, skin pores
