This is my first time using GIMP. I just downloaded it about an hour and a half ago. My main use for this program is cloning. LR3 doesn't have very good cloning skills so I've been doing my cloning edits in picnik. I wanted to avoid loading twice to the internet. So based on a few recommendations I gave GIMP a try. It's free by the way at gimp.org. I think it will be useful for this particular part of my processing. It's different than picnik in a good way.
I'm happy with the results however the best thing ever would have been to MOVE THE NET!
