You can fix chromatic aberration <to a certain extent> by separating the image into RGB layers and scaling them separately. It's fiddly because the centre of the image (where the scaling will originate from) may not be the optical centre of the CA, but it can help. The layers just need to be of a mode where the overlays stack back up to a full colour image - I think it may even me 'overlay mode'. I'm sure there are filters out there for the same, but I haven't found any free ones. Most of the ones I have come across want to
reproduce CA as a low-fi cinema look, not get rid of it.
