Quellenbeschreibung

This workflow designed to restore, upscale and color fix low resolution realistic images and portraits (blury and non-blurry aswell) using FLUX.1 models. Allows you to output 4Megapixel+ images.

Important Usage notes:

jasperai/Flux.1-dev-Controlnet-Upscaler · Hugging Face By default any image you load (even 256x256 image) will be resized to match 1Megapixel, which is base resolution for FLUX.1 model. This setting can be altered in - "Image Input Resizer" nodes. After that, this resized image will be upscaled by whichever value you have in Ultimate SD Upscale node. Prompt is not mandatory, but can help if you get unstable results, as well as denoise values. You can still use value "Image Upscale_by = 1", in that case upscaler will act as an image refiner.

For celebrity images or characters it's better to use celebrity/character designated Lora to preserve accurate facial features.

Zweck

FLUX.1 SmartUpscaler-[2Pass Upscaler]. ControlNet + SD UPscale is for restoring, upscaling, and color-fixing low-resolution realistic images and portraits. It takes a loaded image, can optionally use a prompt, and can produce images at 4 megapixels or more.

Fluss

By default, a loaded image—including one that is 256x256—is resized to 1 megapixel, then upscaled by the value set in Ultimate SD Upscale.
