Deconvolution Sharpening In Photoshop
What is Deconvolution Sharpening in Photoshop? It is an advanced and intelligent way of sharpening images. Instead of the usual methods of High Pass Sharpening or Unsharp Mask which all simply try to make images appear sharper. The way those methods work in their most basic form is by finding edges and increasing contrast where two edges meet by trying to move edged dispersion. Deconvolution sharpening uses calculations and algorithms to accurately enhance finer details and sharpen images by doing enhancing edges in small proximity of similar pixels. As well as finding edges it also looks at textures and tries to determine what they should look like. It sounds complicated but to use general users it made really easy in Photoshop.
There are two deconvolutions sharpening filters we can use directly in Photoshop, they are Smart Sharpen and Shake Reduction. But, for a better understanding and how to use Deconvolutions sharpening it’s best to use Camera Raw.

IMPORTANT To Note About Deconvolution Sharpening In Photoshop:
Deconvolution Sharpening In Photoshop is not for making huge sharpening adjustments. More so it is used to enhance the finer details within our images. This is the beauty of it but it’s also it’s biggest negative. Because the adjustments are so fine it can only really work on an image that is already relatively sharp to start with. Of course, increasing the values of the Radius slider and the Sharpening slider will strengthen the effect, but be sure to look out for following problems that too much sharpening can produce, such as
- Black and white edging.
- A grunge HDR effect.
One of the biggest problems that we usually face when sharpening is Noise. Unlike the conventional sharpening methods of Smart Sharpen, High Pass Sharpening or Unsharp Mask. Deconvolution sharpening adds only a little bit of noise if done right. By having the Radius slider at its maximum value of 3 the addition of noise will be reduced as much as possible.
Deconvolution Sharpening in Photoshop works very well in both Landscape and Cityscape I’d certainly recommend you give it a go.
