Fringing can be rained back and some blooming too by using a UV filter

You can use Panorama Tools to control the fringing. Brian Caldwell has come
up with some formulas:

Hi Shangara
Many thanks for this link info on this subject is just what I have been looking for. I note that Brian Caldwell's work is applicable in Windows. Is there anything I can use in OS9 or preferably OSX? I am really interested in correcting lens distortion, pin cushion and barrel distortion and not necessary corrected chromatic aberation, though that would be useful too.
