Scan vs digital: which is the parent?

Usually when you have two pictures that are the same, whichever is higher resolution is the parent. How does that apply to scans?

I just uploaded a picture (post #842452) which turned out to be the digital version of a scan (post #747892). The scan is, of course, way higher resolution, but the digital version is of higher quality. There are more than a few other cases like this out there, which have the scan parented. Can we make it an established rule that the digital version of a post always trumps the scanned version, regardless of resolution? Or is that the rule already and I didn't know about it?

In general we parent the higher quality and child the lower quality regardless of resolution. There are some cases where it doesn't make sense but it does in most cases.

I almost always make the digital version from the artist the parent because it's the correct coloring.

Since we're discussing this, there's also the case of lineart .vs colored version. Which one should be the parent?

Personally I'd say make lineart the parent, because there are cases more artists will color that lineart.

Previous policy was lineart except in special circumstances like a wip chain.

The lineart is the parent in case of multiple colored versions or a single colored version by a different artist. Otherwise the lineart is just a WIP, and in cases of WIP the final step is supposed to be the parent.
EDIT: ok I missed Log's last post for some reason.

And to OP's question, I tend to make the digital version the parent because there's an actual source + the image is unaltered.

Yeah, most posts were parented like that too. I fixed the ones that weren't for the first 30 pages of lineart (just mentioning this in case anyone wants to finish this, I need to sleep now).

I'll probably check the scans at some point as well if it's decided that the digital should always be the parent, and if nobody beats me to it.

Rantuyetmai and I were having a discussion about parenting of post #909991 and post #904905. I was just curious what others thought about it, because I'd still prefer post #909991 as the parent, even though it's a scan.

Why are you reversing it?

I left a comment at post #904905? The issue was also mentioned in forum #55357, I'd preferred correct coloring over resolution.

I did not notice the comment. But the forum helps to explain. I normally don't like scans at all when there's a digital version available, but I also don't really like jpeg artifacted digital versions like Nakajima Yuka usually posts. And most of those are parented the other way around with the scans as parents. The scan is cleaner than the digital, though it is a bit darker.

I'm going to bring it up in forum #55357 and see what others think.

I would say something uploaded directly by the artist should have preference over an "unofficial" scan. Granted, some are really small, have a "sample" watermark, jpeg artifacts, etc., so it's hard to say they are "better" in all situations and could see why there would be some debate.

It's a pretty clean scan, and higher resolution than the pixiv post, but it also has the extra text from being a cover, and is an "unofficial source". In this case I could be convinced to go either way. If it wasn't for the cover text, I'd lean towards post #909991 for the higher resolution.

I'm not buying either "incorrect coloring" or JPEG artifacts as valid arguments in this case, since neither one seems too egregious to me with my monitor.

In general, in my opinion, quality trumps everything else when deciding the parent. In this case either option seems fine to me though.

To be honest, the artifacts aren't as bad as a lot of the images directly from the artist, but they are still noticable to me.

The other thing is that for this artist, Nakajima Yuka, there are quite a few other images where scans are the parent of the digital due (mostly I'd say) to jpeg artifacts.

I'm going to say post #904905 as the parent but that's only because the scan is a little cropped. Could go either way really, like you all say.

That's actually a good point, and I hadn't really noticed. I usually prefer uncropped images, even if they are slightly smaller.
