In this example I've (over) saturated a free image ( stock image http://www.sxc.hu ) with a saturation setting of +68.
You'll notice the appearance of noise and jpeg artifacts.
What can we do about it?

Solution:[list][*]Duplicate image to a new layer and make this layer the active layer[*]Saturate this layer with a saturation of +68[*]Go to Filter/Noise/Median... and select 4 for radius and click OK[*]Go to Filter/Blur/Gaussian Blur...and select for radius 1.6 and click OK[*]Switch the layer's blending mode to color (deafault is 'normal')[/list:u]

Hmmm... Deke.
Used to be on Apple's site with several other really good ones. Looks like they are gone in favor of a CD.

Yes, I know it's McLelland's style and workflow (PSBible6, p.783), but everything has been done before (except perhaps in some high-end corridors at the far end of the labyrinth). The example is personal, and it's, for those who know, a good reminder, and a good starting point to experiment more.

Thanks Erik, I couldn't have said it better [righton]

Stroker, it's not my intention to win a "I know a technique you don't know" contest. [bustagut]
That idea is just pathetic, especially when you really know me...

The whole purpose of me sharing a technique is to teach people something, to get people excited, get people into action or just to have fun! [excited]
