If you want to enhance the sharpness of your photos in Photoshop you can find the well known filter ‘unsharp mask’, but there is also another useful sharpening technique named high pass. This is the method:
- Duplicate the layer of your image, name it ‘high pass’ or how you prefer.
- On the ‘high pass’ layer run the high pass filter. You can find it in the menu Filter > Other > High Pass. Increase the Radius based on the size and detail of the image. Usually among 0,5 and 1,5 should be enough.
- Set the blending mode of the ‘high pass’ layer to overlay by selecting it on the layers palette (for those who don’t know: you can change the blending mode in the pop up menu beside the pop slider of the opacity on the layer palette)
In this way you’ll get more contrast on the image’s edges and more sharpness.
If you want a lot of fine details use the ‘unsharp mask’, if you want pop out the surface from the background use ‘high pass’ method. But remember…a shot out of focus remain a shot out of focus.
