Contrast Controller

A handcrafted LoRA. (No joke).

Quick description:

It can amplify (strength >0) or reduce (strength <0) the contrast of your base model.

Useful when you want something really colorful, or your base model has oversaturation issue.

Unlike other "trained" LoRA. This is "handcrafted". There is no training, so zero style shifting/pollution. (not an approximation, it is mathematical zero)

The size of this LoRA is 400KB. The file is not broken. Don't be surprised after downloading it.

Working strength is around -0.5~0.5. Recommended -0.2~0.2.

Technically supports all based models, including NoobAI. Unless your base model somehow nuked U-net OUT8 block, which is very rare.

Advance description:

You may have heard about FreeU. It can manipulate U-net blocks output. But it requires software support. What about using a LoRA to do the same thing?

So you can think of this LoRA as FreeU, sort of. It patches U-net OUT8 block (the final block) and manipulates its output.

You no longer have to choose between "creativity/low CFG scale" and "high contrast". Now you can have both.

You can increase the U-Net strength so you can lower CFG scale, and get more creative result and details.
Or vice versa, reduce the U-Net strength so you can use higher CFG to get a stable and clean result, without oversaturation.

Share merges using this LoRA is allowed. However, you must credit the creator and provide a link to this page. Beware that weight pattern will become very unique after this LoRA applied. A normally trained model will never have such kind of pattern.

This LoRA is highly experimental. Remember to leave feedback in comment section. Don't write feedback in Civitai review system, it was poorly designed, literally nobody can find and see the review.

Have fun.
