If you have a white flower on a medium dark background, and you resize, dark pixels are created around white edges.. and also when you do sharpening.
That depends on the employed resizing and sharpening algorithms.
It is clear though that sharpness at the pixel without artifacts is an illusion.
All I'm saying is that, when someone resizes and sharpens image (as it is usually done) dark or white edges appear, and that is the artifact. Dark or white halo. Different image requires different approach.. but sometimes you can just leave sharpening to zero, and resize 50% with bicubic, and you will get sharp image.
No sharpening done, only resize with 50% (two times =25%):
And this is arbitrary resize (73% for example..) with sharpening, (sharpen filter or any other) and then resized to same pixel dimensions as first image:
Here is one from a few days ago. I find that graveyards can be interesting places for photography. This particular graveyard is not all that interesting, but I did like this bronze rose that is implanted on the grave.
