Please see the example images. This LoRA enhances your existing image by increasing the details, sharpness, balancing the color and more.

It works best with bad quality images.

Formula is;
bad image = high strength(0.7-1.0)
good image = low strength(0.3-0.6)

Trigger word & prompting:
Enhance this image

This is the trigger word that you should have in your every prompt. Rest is up to you, you can use any enhancement prompting your image requires. An example of mine(this may not work for your use case):

Enhance this image to high resolution with rich fine details. Sharpen all textures and surfaces, add microdetails and natural grain. Increase clarity and definition across all elements while preserving the original composition, lighting, and atmosphere. Image can be illustration or real photo, keep the original input style.

If anyone wants to try with the exact ComfyUI workflow I used, here is the link: https://openart.ai/workflows/4y8dryqQDEFABVuKEvf4

It has one custom node, Detail Daemon, for adding extra details, but you can skip/delete/bypass it if you want to, not a game changer.
