Re: Again, PF is not CA.
In reply to Anders W, Feb 2, 2013

Of course, PF is a form of chromatic aberration but it is not the lateral CA that RAW converters can nowadays easily correct. PF can somewhat be corrected in ACR where the process is (rightfully) called defringing. The process of defringing will remove colored fringes where bright meets dark, but the RAW converter cannot distinguish between a purple fringe caused by a lens issue and a purple fringe that is really present in the scene. The process of "defringing" can have a destructive effect on all colored edges that could be mistaken for defringing caused by the lens. So it really is a problem that is hard to deal with.
