Step 1. Duplicate the background layer. Point your mouse to the background layer, right-click, and choose Duplicate Layer. You should see the background copy as your first layer. Rename the layer as High Pass. I like renaming my layers as it makes it easier to identify them when working on several layers, but I will leave that up to you.
Step 2. Go to Filter, Other, pick High Pass and adjust the radius to which the sharpening will be applied. I typically use between 2-6 pixels. The higher the pixel, the stronger the effect, so it is best not to go overboard. I’m using 3 pixels for this tutorial.
You should now see the layer turn into grey, with a prominent outline of your image.
Step 3. Change the blending mode of your High Pass layer. On your layers palette, make sure that you have the top layer selected. Change your blending mode to Hard Light and keep the opacity to 100%. If you think that the effect is too strong, change the blending mode to either Overlay or Soft light, or you may decrease the opacity to soften the effect. Play around with the different blending modes and opacity until you get the desired effect.
Step 4. Flatten the image. Once you’re satisfied with the sharpness of your image, you may now flatten the layers.
