Sharpening ?

OK,
As we all know sharpening is necessary, multifaceted, confusing and EVIL...

Please tackle this image with your usual work flow and then...
With LAB sharpening only.
I want to see how well we can do in LAB versus having to add a additional tools / plugins to the work flow.
LAB sharpening does not have to occur in CM but you might want to copy a channel when you are in CM for later paste into a channel in PS.

Use CM for color and saturation. 

This is sort of out of bounds for the CM work flow but it is a part of the larger question and I'd like some feedback.  I do read the Color Theory group postings and I understand this is a serious hairball for everyone.

Slightly lost me there Greg - you want us to pp as normal and then sharpen
But in Lab only - and what's this about CM?  I didn't think you could sharpen in CM?

Sharpen in Lab can occur to some extent when you adjust the L curve in CM.  "Some"...Have used this in the past to sharpen lightly. 

I would like you to try to sharpen by converting the image to LAB and using only the PS tools.  I am trying to go as simple as possible.  My thoughts around this are that I really do not want to have people saying that they "need" focus magic or any other sharpening tool.  I just want to know before I go there that there are some things that you can do in PS without extras. 

I have just re-read Chapter 5 of Canyon Conundrum and Dan describes a LAB only sharpen that can be done in PS without additional tools.  I have tried and find some of it acceptable but confusing at first.  I want some input from you guys to see if it is an addition I would need to talk about in CM201.

so...

Do one run at this in your normal work flow completely..then...
Do one run at this using LAB mode for the sharpen....instead of your usual sharpen tools unless you just use PS tools for sharpen.

Am in a bit of a rush tonight, so here it is
image-1 CM correction - 3mins
image-2 Lab sharpen - 1min
image-3 CM correction + FocusMagic (just for comparison)

PS image size is very important when sharpening - so to show it on the forum, I reduced the size to 25% before starting

ganna:
1. In CM set highlight, shadow and one of the light coloured rocks center foreground as neutral. Lighten the picture a bit. ±3minutes.
2. In PS changed mode to Lab; Sharpened L channel only first USM radius 60 Amount 20 to boost midtone contrast and then smart sharpen 50% radius 0.8. ±3minutes
