Trying to make a new process

 The previous process was giving unsatisfactory results, so we tried a new process.

Base image (model : perfectrsb v6321 )

Before upscale, I2I Inpaint first with SD 1.5 (model is : MH v2).

Upscale 1.4x 3 times and 1.2x once .

Applyed detail deamon and ddsd extension

The hair looks over-sharpened, but the other parts seem fine.

Inpaint again 

The hair texture still appears over-sharpened, while the pantyhose texture feels slightly lacking, but overall, it looks fine.

Remove blemishes.

Add shadow noise, skin texture, sharpen, color and lighting contrast.

Final edited result.

In this case, new process has much better result.

The texture details could probably be improved by using Flux with ComfyUI for inpainting, leading to better results.

 All image has exif info.
