Creative/fidelity upscaling with SDXL | Forge WebUI
🤪 In this video tutorial, we explore model upscaling, latent space upscaling (I2I), and two-step upscaling (HiRes fix) using SDXL and Forge WebUI.
🤯 Wonder what the magic behind cloud-based upscalers like Magnific and Krea is? Follow these tricks for creative upscaling. You will be surprised; it is much easier than you think, but good hardware helps a lot.
😎 We also discuss checkpoints and provide tips and tricks for avoiding problems when upscaling images.
