This LoRA can do a lot of good things such as detail enhancement, creative upscaling, photo restoration and quality improvements.

It's a Image-to-Image(I2I) edit LoRA, so it will require image input, but you can use with Text-to-Image as well.

I will be honest here; model itself is quite capable of improving the image, just by prompting it, without needing of this LoRA, yet this LoRA improves the quality and guidance of the model itself on these tasks because it's trained on a dataset that contains pretty good pairs.

If you are aiming for upscaling to higher pixels, please use this very simple workflow + add Load LoRA node between Load Diffusion Model and KSampler as usual and load this LoRA.

If you are not aiming for higher pixel upscaling, use it as usual without needing the workflow above.

Trigger word is: enhance this image, yet i strongly recommend putting your own words/sentences afterwards. Keyword alone might not give you the look you are after.

For example I'm using this one as a starter, but this prompt doesn't work well with the illustrations, sometimes realistic photos as well, so I'm deleting the "sharpen textures", so please find your own version of the prompt if you are not happy with the outcome:

Enhance this image to high resolution with rich fine details. Sharpen textures and surfaces, add natural microdetails, and improve clarity and definition across the image while preserving the original composition, lighting, atmosphere, and visual style. The input may be an illustration or a real photograph; preserve the original style.
