Hello!

@superbeasts_ai and I (@midjourney_man) teamed up to create this ComfyUI workflow.

It is intended to upscale and enhance your input images.

We introduced a Freedom parameter that will drive how much new detail will be introduced in the upscaled image. FYI, values closer to 1 will stick to your input image more, while value closer to 10 allows more creative freedom but may introduce unwanted elements in your new image.

You will also notice an HDR effect that can be set for pass 1 and pass 2.

Couple things to note:

• There are two passes. Depending on the upscale size for pass 2, it may take a while to generate your final image. If you want to save time, you can disable pass 2 altogether with the built-in switch.

• We always downscale the loaded image to the nearest SDXL resolution (E.g. 1024). As a result, defaults scale values will result in 2K and 4K final images for pass 1 & pass 2, respectively.

Feel free to play with the settings to see what works best for you and your style. Do not be afraid to test other models and LoRAs. Last but not least, you can also use different CN models as needed (example: Open Pose).

Enjoy! :)
