Let's take a look at the effect comparison:
1) open a photo that requires sharpness
2) copy layers
3) press CTRL + I/CMD + I to reverse the tone.
4) set the opacity of the layer to 50%, and the screen will become gray.
5) Select filter> blur> surface blur
The radius of the value is 3-5, and the value of Threshold is 15-20. The value is adjusted based on the image size.
6) Keep the transparency 50%. Copy the layer (CTRL + ALT + SHIFT + E/CMD + OPTION + SHIFT + E) and delete the middle layer.
7) change the layer mode to "overlay" or "Soft Light". If necessary, you can re-copy the gray layer to make the screen clearer.
