I've long wanted to train a LoRA to reduce the artificial, AI-generated look of my images. To achieve this, I prepared a training dataset of real-world photography, and trained on Z-Image Base, Z-Image Turbo and Krea2. I will release these three LoRA models then. I found that while the performance of the LoRAs varies slightly across different base models, the following improvements are achieved overall:

• The overall lighting and shadow realism of the image is enhanced

• Human skin appears fairer and gains more translucency

• The contrast between light and dark areas is more pronounced

• Textures and details look more authentic

• The overall aesthetic presentation of human subjects is improved

• High generalization performance, no negative impact on the facial features of character LoRAs

Recommended Settings:
Trigger Word: virealism
Weight:

• Z-Image Base LoRA used on Z-Image Turbo: 1.5

• Z-Image Base LoRA used on Z-Image Base: 0.7

• Z-Image Turbo LoRA: 0.6

• Krea2 LoRA: 1

Sampler: Euler Scheduler: simple / ddim_uniform

Comparison/来对比一下看看：

我一直想训练个自己的lora来降低生图的AI感，于是我准备了真实摄影的训练集，在zimage base、turbo和krea2进行了训练，我会先后发布它们。我发现虽然在不同大模型上，lora效果表现略有差异，但总体得到了以下改善：

1. 画面整体光影真实感得到提升

2. 人物的皮肤更加白皙、通透感增加

3. 明暗对比呈现增强

4. 纹理与细节更真实

5. 人物美学提升

6. 高泛化性不影响人物lora面部
