Sharpening your images using the High Pass Filter – Photoshop
One of the easiest ways to sharpen your images is to use the High pass filter. There are many ways to sharpen images in Photoshop and Lightroom. One of the easiest methods I have come across is to use the high pass filter. The high pass filter works by only sharpening the edges within the image, leaving the rest of the image untouched. This means that it does not sharpen and exaggerate unwanted noise or grain within the picture, unlike some of the other filters within photoshop. > The best thing about the high pass filter is that it is really simple and easy to use, unlike some of the other sharpening options.

Below you can see the two images before and after high pass sharpening.

Select the image layer by clicking on it once, then duplicate it. Using the keyboard shortcuts “ctrl + J” (Windows) or “cmd + J” (Mac), or Layers > Duplicate Layer. Duplicate the unlocked layer 3.) Then select the duplicated layer then Filter > Other > High Pass. Once you have high pass filtered the duplicate layer the image will turn grey. Select a pixel radius between 1-20, ideally no where greater then 20 as it may over sharpen the image. Select the high pass filter

Slect a radius between 0.1-20 pixels 4.) To view the high pass filter on your original image you need to change the overlay options on the high pass filter layer. Change it from normal overlay to soft light. I have found that sometimes this over sharpens the images so I reduce the opacity of the high pass layer from 100% to typically between 60-90%. Reduce layer opacity and blend mode to soft light 5.) The final thing to do is to merge the layers and save the image as a Tiff or jpeg.
