A Method for non destructive sharpening
I learned this technique in a Canon Digital forum . It allows you to sharpen an image without blowing away the original data from a scan. The technique was originally developed to sharpen images taken with earlier digital cameras shooting .jpg format. I found that it worked brilliantly for images that were soft due to scanning or even due to my eye. Photoshop ver. 7 is the tool used. I have tweaked the original info a bit.
Take your original image (pic 1) duplicate that layer, de-saturate it using Hue/Saturation (pic 2) then open “Filters>Other>High Pass.”
In the High Pass dialog, set the pixel radius to 1.0 (pic 3)
On this same new layer open curves (ctrl M) and adjust as shown in pic 4.
Change this layer’s blending mode to “Hard Light,” you should see the sharpening effect now. It most likely will appear harsh. You can adjust the sharpening effect by decreasing the opacity amount to your taste. I find that setting the opacity for the effect layer between 30 and 60% gives desirable results (pic5).
The definition of the effect also seems to be affected by adjusting the amount of High Pass or Curves for the effect layer. I urge you to experiment.
