So, this is another quality restore 2 steps pipeline. Use both loras in presented (or built in second image) workflow (I tried them both in 1 single pass - wasn't very good as I remember, but may be wrong, it was late night).

TLDR:

Denoise lora - maid to clean grain from pics (sometimes Klein and other models thinks that grain is ok and lefts it, and don't do with picture nothing).

Overall quality lora - for enhance image quality (it was maid first, but works not always because of grain), it is pretty good at deblur.

===========================================

Flux 2 model take from here (v1): https://civarchive.com/models/2339723/flux2-klein-9b-true?modelVersionId=2631758

Yeah, there's v2 version now, but I did some tests and results was not very good (default flux2 9b base model also works not very good).

Denoise trigger: d3gr4in, delete grain from this photo

Overall quality trigger: f1xThephoto, fix this photo (add ", restore the image quality, remove any compression artefacts, remove any haze and soft edges, create a professional photorealistic photograph with natural lighting" for better result).

Overall quality lora (lora 2) inspired by this: https://civarchive.com/models/2474084/ultimate-upscaler-klein-9b

which works fine almost all the time, but I got one old photo on which I test pretty often various new stuff and upscaler lora (and all the others I tried) doesn't affects on it. So, I start to dig, created my own quality recover lora (lora 2 here), noticed that it's also not working on old photo, noticed that Klein2 and much others just sees photo grain and thinks that it is normal and not cleans it, so I create one purpose kinda denoise lora (lora 1 here) which cleans photo of grain and some other pixel stuff, and than Klein 2 can see beyond the grain fog.

Not tested it all much, believe it may not work for some special photos.

For addition - you can upscale result with SeedVR2 (not included in wf, maybe other day).

Known issues:

Denoise lora:

*sometimes removes freckles from faces (and some other small repeating details). May be fixed by using additional consistent edit lora for flux2 (this works nice https://civarchive.com/models/1939453/consistence-edit-lora?modelVersionId=2810265, better than 20260416 release).

Overall quality lora:

*sometimes can turn night into day in landscape pictures.

*may increase lips color (and makes colors brighter than on original picture, I trained it that way, but now I think it can change sometimes whole mood of the picture).
