R: Sharpening image

From: emvarona
Subject: [Gimp-user] Can't get this image sharp with GIMP. Any
    suggestions?

[...]

i've got a bad digital camera and want to work over the

results. Bad in this

case means, that i've got good resolution and good

results concerning the

light, but a bad sharpness.

My idea is, that if i've got a good resolution, what

the fact is, there must

be a way to sharpen it. Isn't it?

Not at all. If the content is not sharp, the fact that it is represented with a lot of pixels does not imply that the sharpness is there.

If you print a blurred image at 4000 dpi, it does not improve. So, if the lens has "printed" a not-so-sharp image on your camera sensor, in general you cannot recover a hypothetical sharpness that is there, but is hidden. (You can recreate some sharpness, which is what the commands "Filters->Enhance->Sharpen" and "Filters->Enhance->Unsharp mask" do.)

Unfortunately it seems that the link you provided does not work, so I don't know exactly what you need, since I can't see your image.
