i get the point of them, but ultimately i don’t feel like they fit the context of an art archival site
they waste bandwidth and they introduce way too much artifacts to the images they were used on, causing smaller details to looks very mushy and vague
its not really an “enhancement”, it’s like sharpening a blurry image in photoshop! it looks better from far away but as soon as you zoom in you’ll see tons of artifacts that permanently lose information of the original image.
and besides, the tools for upscaling artwork are widely available and free, if anyone wants an upscaled image there’s a good chance they’ll be able to make their own. there’s even sites like https://waifu2x.booru.pics/
what do you guys think?

I really don’t agree on any of these accounts.

If an image is saved at 40% jpeg at 600 pixels, you can’t really make it worse. I think it far improves the quality.

And they suck. I use professional enlargement software that isn’t free and works far better. I also will manually edit the image in some cases.
what do you guys think?
An argument could be made that the original shitty version be saved too, but of course on this site we do link the source.
But as I own the site I likely won’t change the policy on allowing AI enhanced images.

forgot to respond to this, sorry!
honestly i’m for the %shitty% original versions being saved alongside the upscaled versions if possible
for what its worth i don’t know anything about your process for enhancing images or how refined it is, though i generally have had a good experience with free AI models when upscaling artwork myself for personal use, so i’m not against upscaling as a concept (keeping in mind the limits of the technology)
i just mainly feel like entirely replacing a source image with a modified one hurts the booru as an archive, sure there’s some low-res art that are literally just crunched up .jpgs that got tossed around the internet too much, but there’s also art that could be deliberately made at a lower resolution. would it be a good idea to upscale and entirely replace something like that?
personally i dont think so
but if source images can stay then upscale all the images you want tbh, i’ll admit me calling for disallowing them is a bit much if we can just have both
and if anything, keeping the originals around also has the benefit of allowing for better upscaling in the future as software keeps improving

this ones actually a great example https://cubfur.gay/images/6226

the low resolution and aliased brushes noriburu uses in their art is an intentional choice, upscaling it completely destroys the original look of the image by making it adopt a more traditional pen-like lineart
and the lineart isn’t even consistent to what someone drawing would pens would do, there’s lots of “stepping” around the round corners due to the intentional stylistic decisions of the original image. especially around his cheek! to me it doesn’t look good at all

It’s not using specific non-aliased brushes… It’s using a free, Flash-based oekaki 15+ years ago.
If the artist requests, I’ll delete it.
