idk the original really hurts my eyes
i'll admit that my edit was pretty piss poor though, i just used an image editor for it, so it's not a good comparison point
Whenever your scale something up past 100%, you're not comparing the image anymore, you're comparing the software's scaling algorithm. If you didn't choose a scale factor that's a power of two, it's going to be really off as the software has to do funky interpolation things to make that fit. Even if you did choose a power of two, it's still likely the software messed with it, rather than simply go "one pixel at 100% equals four at 200%, and done"
tldr; scaling things up not only magnifies things you wouldn't normally see, but also produces defects that weren't there in the first place.
