Exercise: Sharpening for Print

This exercise surprised me.

In it we are to take an image without any form of sharpening and then create three more version of the same image with varying levels of sharpening. From the RAW converter I selected the following image taken from the Olympic Torch bearer that passed my house with 0 sharpening and opened the image in Photoshop.

I then applied a 20%, 100% and 250% amount of sharpening with 1% radius and printed each one out. On the screen I would say that the best image was 100%, this is what I normally sharpen to. When printed the 0% and 20% images were clearly in need of additional sharpening whilst there was very little difference between 100 and 250%, especially when compared to the screen. It would therefore suggest that for print more than 100% is required as it is very clear. Looking at the skin tones those these do appear to be over sharpened and harsh but nowhere near as much as the screen image which look frightful.

Conclusion: open at the moment, certainly for screen 100% seems to be perfect, for print I think it may now benefit from a little more....
