Is there software available that will allow you to correct for spherical aberration (SA) in a photo? I know Gimp will allow you to add "perspective" which will allow you to bend photos a little bit, but it only has "handles" at corners, and I'd like to add multiple adjustment handles to correct for the non-linear distortion that SA causes.
Any suggestions on what is out there, or if it SA can be corrected for, even just a little bit, in Gimp or other editing software?
