chromatic abberations in LR4

  • Question
  • Updated 6 years ago
chromatic abberation cannot be corrected manually in LR 4. Does LR 4 automatically do it as good as it could be done manually? As far as I can tell: No.
In previous LR versions it took some fine tuning - is the new automatic correction capable of that?

The Auto-CA reduction is a good tool and can do automatically what it took much tweaking to do in the past. There are, of course, always edge cases that defy simple removal.

In general, most images I've attempted can be handled automatically with good results. I haven't yet missed the tool in PV2012. You can always revert to PV2010 to attempt a better CA removal. A quality lens profile will improve the odds too.

The team appears to be working to further tweak the abilities of the Automatic Removal. On the User-User forums, there have been requests for and deliveries of images that are lacking with automatic CA removal. I wouldn't be surprised to see further enhancements.

The new automatic does its own fine tuning, and it has more internal adjustments than just the two simple sliders that were there before.

oh thats good to hear, thanks =). I'm curious whether that's just calculated by the lens profile or if LR analyses the pixels...
