>>>/hr/3764922And, some photo editors do a decent job. You can't just resize and expect miracles. You have to be prepared to make some adjustments if a simple resize doesn't look good. The source file quality is also very important. A high quality source can upscale just fine for most needs. If you're jumping from a solid 2K image to 4K, the majority of upscales will be just fine for a pape. Try to jump from a 720 to 4K and there will obviously be problems.
Not even slightly joking, IrfanView does a better job than waifu2x. Save your upscaled image in 600 or 800 dpi. Don't expect much if your source was a 72 dpi .jpg saved at 70% compression. If your source is saved at 90% compression and starts out with 300 dpi resolution, you can do things with that.
Saving your final resize/crop in lossless .png is always a good idea. If you can't do that, then use 95% compression on lossless .jpg.
>pop-quiz:> which images in this thread are upscaled from a smaller image? I posted at least three, and probably five or more.> current pic related doesn't countBut, go ahead and try it at 4K and see how it looks. I'll be curious about feedback. Most basic attempt is to tell your OS to stretch it to fill your 4K screen. Then try some other options, even post it to the /hr/ thread I linked above and see what that guy can do with it using Gigapixel.
