I seldom modify pictures, so I don't use the software very often.
Last year, I modified a picture by only applying a GIMP filter on it but I cannot remember which filter I applied at the time nor the settings.
If you could direct me to the proper filter that would be nice. If you're able to give me the settings, you're the man :)
I've already looked on this page and I can't figure out which one I've used.
