3. Choose the amount of sharpening. The High Pass filter sharpens only the edges. The amount of sharpening de-
pends on the size and resolution of your image. If you are working on full resolution, the radius should be between
0.5 and 5 pixels. If you apply too much sharpening, the image could start developing unwanted artefacts and halos
and noise. Best to be subtle about sharpening

4. Adjust the blending mode. In the Layers palette, select the Blending mode drop-down menu and choose
Overlay. If you find the blending mode too strong, you can adjust the opacity of the high pass layer.
In case you do not want the whole image sharpened, you can use a Layer Mask and choose the areas in the image
where you want the sharpening to be applied.
