Yes, and it's common to evrything you do. So why does converting to Lab allegedly make it so much worse?

The bigger question is; Why would anybody use LAB at all these days, but for some arcane process few folks are using?

There is no real benefit from using LAB in a daily Photoshop workflow given the massive changes in the various tools and PS algorithms since the days of PS6 & PS7, you might have noticed that PS CC 2014 is currently = PS 15.1.0.

So far the only reason those who actually use LAB for some purpose or another can give (Peter says he likes to sharpen in LAB, when what he means is he likes to over sharpen using any method he can get his hands on) is some guru writing 20 years ago has claimed that it is the way to go. Frankly for most photographers running current editions of PS CS5/CS6/CC/CC 2014), using LAB for anything other than some sort of specialized work, is a waste of time, and trying to find some way to defend its use in a never ending Usenet screech-fest thread, is an even bigger waste of time.
