Readers.
to sharpen a picture, is the best thing to do that in "L" from the lab mode.
Curvemeister has a "L" mode, but it don't work this way.
You must do it in Photoshop (X), or in another program wich have LAB mode.
Gimp 2.2 has LAB mode. On a difficult way , I think.
Here is how you do it. Many is written in dutch but I think you can find your way.
I have made this picture for myself.

Mike and other readers,
Sharpening in Lab mode is difficult in P.S.E 4.0, then there is no Lab mode in p.S. E. 4.0
Till now, I do it on a difficult way in Glimp 2.2.
But till a couple of weeks I have also the effect plugins from The hidden power of P.S.E 4.0 written by Richard Lynch.
In there is a LAB mode. A( lumin) and B( color)
They don't work automatically. I think it is , because my P.S.E. 4.0 is in dutch.
But fortunately the way it worked is described in the book and I can do it with hand.
And indeed I get some sort of Luminosity.
How I must assemble again a color picture , I don't know yet.
But the strange thing is compared with the "L" from Curvemeister , there is a difference.
Mike, can you explain to me why.?
The principle how Richard does , is to make a layer of 50 % gray what is extracted of the original. ( I think)
On the end, the goal is to sharpen in Lab mode in P.S.E. 4.0. and not Gimp 2.2.

Hi Fritz, if you just want to sharpen in LAB mode ( the lightness channel) using Elements then duplicate the image as a layer and change the blend mode of that layer to luminosity and apply sharpening to this layer, then you will be only sharpening the lightness channel without effecting the colour components of the image.
