[Gimp-user] Chromatic abberration

[Peter Taylor]

I have found that a small low cost program called Ptlens does a very 
fair job of reducing CA, and various other lens distortions.. It only 
runs on Win2K, XP or Vista or Unix with a windows simulator, either free 
standing or as a PS plugin. Profiles are available for many cameras.

It costs $15 for a full license
