Step 1
Open the photo and duplicate a layer, above the original layer
Step 2
Use the filter on the copied layer, Filter-Other-High-Contrast Preserve
Step 3
Change the blending mode of the copied layer to "Hard Light". For a better effect, you can also copy this layer. The blending mode is also set to "Hard Light". The initial clarity has been achieved. As you can see, with such sharp processing, the poor pixelation results without the sharpening filter.
