Dark

Lower the brightness. And make it more photography-ish.

All cover images are directly from a1111, no upscale, no face/hands fixes, even no negative prompt.

I trained this LoRA because anime models have a very high bias towards bright images. So even if you prompted something dark, it still not dark enough, most part of the image still very bright.

However, I can't find a "dark" LoRA that is for natural dark. Because existing LoRAs are

• Either trained on bright images, so you have to use negative strength to go dark, which is doable, but the quality is really bad.

• Or focusing on pure black level, trained on pure black anime images, which causes style shifting, losing details, sometimes deformed faces and backgrounds.

This LoRA is trained on a sub dataset of "Touching Grass", only low brightness real world images.

• The dataset is big (~400 images), and very diverse.

• Only environment, no human in dataset. So it will not "pollute" your characters style. Can be applied on both pure anime and realistic models.

• It's dark, not black. The training images still have a quite wide brightness range and are full of details. E.g. cityscape at night and full of small building lights. So the model will know what it should do, just go dark, rather than go crazily black. You will not get deformed bodies, faces or backgrounds. Instead, it makes the dark environment more stable, and adds more details.

Useful if you:

• want something very dark, darker than prompts can achieve.

• want to lower the overall brightness and create a photography feeling.

Trained on illustrious v0.1, but I tested it on NoobAI as well. The effects are very good. So I don't think we need a separated NoobAI version.
