Correction of Chromatic Aberration: how best?

[Hening]

Hi Stas!

When I try to find the optimal values for CA correction, I find that the different "slices" would require different values. Which would be the best way to proceed:

1-Correct all slices individually before stacking
2-Correct all slices by the same value, before stacking, choosing the value of the slice where CA is most obvious, typically branches against sky, distant or near infinity
3-Correct CA AFTER stacking

?

My workflow is: shooting raw, converting with Raw Developer, CA correcting the TIFs in Adobe Camera Raw.

Kind regards - Hening.

I think the results would be pretty the same, but I would prefer to correct CA before stacking.
