Fixing Blurry!!

I tried the search function, and didn't find a topic like this... So here it goes...

I am quite new to making wallpapers and graphics. I've downloaded GIMP and have experimenting with it for quite some time. But I am still learning!

My question is this: What is the best way to clean up a blurry image? My problem seems to be when I enlarge an image, and It gets quite blurry.

I have visited the GIMP website and followed the tutorials as best I can. But I wanted to see if anyone had any methods that they like to use when cleaning up blurry images. Any advice would be appreciated! Thanks! (^_^)

I wanted to ask the same question...................can someone explain how to resolve this problem?

There isn't much of a solution for this problem. When you enlarge a graphics image, to maintain the same level of detail/pixel, you need additional graphics information THAT DOESN'T EXIT. There are picture algorithms that try to sharpen a picture by exaggerating the details difference that it does find, but it's no substitute for real grapics data.

This is why it's important for raw graphic image scans to have a high resolution image. It's easier to throw away unnecessary graphic detail data by shrinking a picture to fit, then it is create new graphics data by enlarging it...

Yeah, there's no way to create an image with high quality because instead of adding more pixels, it makes the previous pixels bigger, causing the loss of quality. Unless the image is a specific type of file that can be enlarged and shrunk(I.E. a vectored image made in Adobe Illustrator), there's no way of preserving the level of quality that you want. Unless you want to go through a large hassel of cleaning up the image, I suggest you keep it the size you got it or make it smaller.

It's called vectoring and you should try to find tutorials on that on Google. It's time consuming though - first try to request a higher resolution in /r/ on 4chan.

If you are talking about a raster image becoming blurry, then I think you should use the term pixelated instead of blurry. This is because some minor pixelation can be fixed with a good blur technique (smart blur, glussian blur, etc).

THat's i right the only way to fix a pixalated image is through vectoring... or i've also tryed just recoloring... but that doesn't work as well as vector.

Well I've never vectored (*cough* hint-hint ;) ) but I have done the recoloring. No matter how good you are it's never as good as a sized down scan just because of the difference in details. Smaller=less details.
