This conversation has been merged. Please reference the main conversation: Lightroom/Camera Raw: Improve chromatic aberration removal
12 months on and I'm finding that mostly the automatic lens profiles work great, but CA control is just pretty much non existent. I also have defringe set to ON too, and occasionally I'll use the colour sliders, but nothing I do will get rid of the CA in my shots.
So... firstly does anyone have any pearls of wisdom for fixing it on a global basis? If not, Adobe, please make this part of your development for LR4 - it's the only thing which is letting down an otherwise fantastic rendering :)
