My workflow now is, instead of using Ultimate SD Upscale, is to upscale and then manually inpaint details with a well-crafted prompt for that part of the image and even some manual corrections and additions. It gets much better results, flexibility and avoids the usual vertical an horizontal artefacts.
This is the GIMP file with only the inpainted bits
Upside-down. Not what I expected but I love the results😍
Prompt: 'A serene suburban street where each house has an upside-down door, and people walk in and out on their hands, their feet pointing skywards, defying gravity. --ar 3:2 --v 6'
lol, I've been blocked from #Midjourney for 24h because my non-sexual prompts generated too much nudity for their taste 🤷 Oh my, what will I do with my life now??
@WeavingWithAI One of the reasons I stay away from proprietary models that only run on cloud services and prefer to run SDXL locally, even with its limitations.
