I know they often use 'Magnific' for that. But I achieved the same results with the Stable Diffusion inpaint model 'Realistic Vision'!
AI doesn’t necessarily make your image better—it should already be good beforehand.
Things like color composition also play a big role. AI just adds the final touch.
You can try Magnific—it definitely saves time, but it's very expensive!
That’s why it’s better to use Stable Diffusion with inpainting—just improve small 768x768 areas where needed, like plants or grass.
I’m not a Stable Diffusion expert either—there might be even more efficient approaches.
