I’ve been playing around with the perspective correction feature in Gimp 2.0, and while it’s invaluable, I’ve noticed that it really has a tendency to blur up a picture.
You can reduce this some by not editing JPEGs–it’s always best to convert JPEGs into PNG or TIFF format before editing anyway–but it only reduces the problem. And Gimp’s sharpen tool leaves a lot to be desired.
Enter SharpControl.There’s something of a tutorial available online. To be honest, I really don’t know what most of the things he’s saying mean. What I do know is that I can just load an image into it, take the defaults, and get a better-looking image than with any other program I’ve ever used. And if I fumble around a bit, sometimes I can get lucky and improve it even more.
Hey, I was trained as a writer. I had to stay after class one day to get what little Photoshop training I did get.
The program only speaks TIFF or JPEG, so you’ll have to convert to TIFFs if you decide to load into the program from files. The alternative is to paste the contents of the clipboard into the program, manipulate the image, then copy it back to the clipboard and paste into your imaging program.
It’s a free download, so if you’re playing with fuzzy images, go download it now.
