Reduced Noise Sharpening Method

Here’s a sharpening technique that allows you to provide a relatively noise and artifact free sharpening to an image without using the standard Photoshop sharpening filters.
First make a duplicate layer of the original background layer by typing Ctl J (PC) or Cmd J (Mac). On the filter tab go to Filter/Other/High Pass. The image will appear as a grayscale image with accentuated edges. Adjust the slider at the bottom of the high pass filter dialog box to from approximately 1.0 to 3.0 or until a sufficient amount of edge detail is visible on the image. Then click ok to apply the filter.
Then with your duplicate layer highlighted, change the mode (box at the top of the layer panel) from ‘Normal’ to ‘Overlay’ or ‘Soft light’. (Overlay is a bit stronger of an effect). You can then adjust the strength of the layer sharpening by changing the opacity of the layer using the ‘Opacity’ slider on the upper right of the dialog box.
This effect tends to sharpen mostly prominent edges and ignores the open areas like sky and large smooth areas of relatively low detail.

To take this one step further you can create an action for this series of steps and it will act as a "one-click" method to reduce noise/sharpen your images. As Don said, you will end up with a layer so adjustments can still be made after completing your action. For more info on how to create an action in Photoshop if you haven't done this before, here's a pretty easy diagram (there are more, just google) -

Brilliant idea. I still do the super sharpening in the LAB lightness channel to avoid halos and the high pass just for effects. Should try this one. Thanks.

>Creation stands on its own. Any meaning or value is derived by each viewer solely from within the boundaries of the work itself. Photography, to me, is simply a wonderful method to express that primal desire to reflect and thus express truth or beauty (some say they are the same thing). It also may be simply the desire to convey a profoundly moving effect. To that end, the viewer either 'gets it' . . or is not moved.
