Exercise 24: Sharpening for Print

For this exercise I sharpened a number of photo for print. I did three versions of sharpening to different degrees.
I have never sharpened an image. So I needed to practise a good few times. This is a good photo to sharpen, because there is a lot of edge detail.

 Unsharpened Photo

1st Sharpened  Photo

I only sharpened this photo a little. There seems to be not much difference between screen and the printed version.

Sharpening setting:

Amount 78

Radius 0.6

Threshold 10

2nd Sharpened Photo

This photo has been sharpened a lot more than the first  photo. You could see it more in the printed version then in the first photo.
Sharpening setting:
Amount 105
Radius 2
Threshold 20

3rd Sharpened Photo

 I think this photo is over sharpened. I think the sharpening is about right in the first photo.
sharpening settings:
Amount 150
Radius 3.6
threshold 30
