With the zooming we have completed the preparation and now it’s time for us to sharpen our image.
First we will select the duplicate layer we have created and then we will go to Filters > Enhance > Sharpen (Unsharp Mask)
A pop up window for an unsharp mask will appear from where we will be able to control the sharpness of our image. In the window we will see three settings which are Radius, Amount and Threshold.
These three options do their own set of work for sharpening an image. Radius ensures pixel numbers when we sharpen our image. So you can adjust how many pixels you need by writing the amount in the radius box.
On the other hand, the Amount option lets you control the strength of your sharpening. So you can decide how sharp you want to make your image.
Lastly, the Threshold option indicates the difference in pixel values and where the sharpening must be applied.
If you accidentally mess up any of the settings then you can undo it and try again to aim for perfection. It is hard to get the numbers perfect and that’s why you have to play with the settings until you learn and get the best fit.
When you are satisfied with your settings click OK.
