I have found that using high pass on the luminiscence layer in LAB tends to minimize halos.
Actually it is a good idea to do any/all/most sharpening on a luminosity layer, LAB or not.
not always, since the conversion to lab and back is not lossless.
and back was a damage free process, that is, you would end up with the same color co-ordinates when you arrived back from Lab mode."RGB>LAB>RGB is damage free, but CMYK>LAB>CMYK is not. The damage isn't all that great, so in many images it pays to come out of CMYK so as to take advantage of LAB's strengths; sharpening, however, is not one of these cases. .... Dan Margulis" --
