Misc Attempt Need some help and critique

[harumi863]

When I resize large images, I get this scratchy box patterns on my grays which I can't seem to get rid of.

Here is my original raw: http://i44.tinypic.com/5kq5og.jpg

I use surface-blur radius 18 threshold 10

Here is the result: http://i42.tinypic.com/2vl15cj.png



How do I get rid of it?

Any help is muchly appreciated.

Hmm I also sometimes have problems with this. Try step resizing or a denoiser like neatimage or Topaz. Something I just though of is to zoom the page in so it has the right hight and then take a screenhot lol. Im not a pro on this stuff ad it only happens sometimes but you can try that

EDIT: Don't know if this works but maybe try changing the dpi. But could be that that only matters when you print it.
