A human face is the easiest target - because AI upscalers can make up a "fake" face realistic enough to fool most people.

Especially something as standardized as a passport photo.

Full disclaimer: the Enlarger app is something I did.

Fuller disclaimer: this kind of a "postmark"-sized pic blowup test case is borderline unfair to every model in the comparison, mine included.

Enlarger's ear lobes are molting!

Most any upsize looks better if you toss hue protected noise back in; you've made good use of that point.

Thanks. Yeah, I used to do the tug-and-pull of scaling, then adding noise and sharpening, scaling a little more, adding more noise, adding more sharpening, etc. to ad nauseam. And photoshop sharpening was too much always for my taste.

At scale, this tool should speed that process up a "bit". Let's say 100s of photos.
