I'm correcting a photo that has about 3 px of CAs at the border in ACR 4.1. This photo has a leg of a pier with the CAs surrounding it. I went to the correction tools, and I got something resembling correct. However, there's a "halo", AKA there's a 1px section that looks correct (sky in this case), then a 1px section that resembles in inside of the section (pier leg), and then it continues as normal. What happened? Is there an automatic way to correct the CAs (a plugin or otherwise).
