Anyway, to continue the LAB discussion from the Leica thread. I've chosen a couple of images that present sharpening difficulties and I've used a standard method - one in full RGB space one in LAB space with only the L channel. I have chosen a more aggressive sharpening than usual so that the differences can be highlighted.

The bottom line for me is that I really can't tell the RGB/L apart. To me the differences seem extremely slight but perhaps I'm just blind to that type of subtlety..
This is ancient (I am just going carefully through the whole thread to read up on interesting topics), and I have to agree that I cannot see any difference in the sharpness in your pair, but I feel there is a slight colour difference between almost all the pairs, and the Lab shot looks better in each case. In the shots with a blue sky, the blue is better, brighter, more natural in the Lab shots, whereas the regular shots have slight colour drifts to unnatural colours like purple.
I will have to try this out myself and see if I can see a difference in my own shots too.
