Restoration in Action
Learning how to fix damaged areas in photos is not a step-by-step
process. Rather, it is learning how to identify problems and make
strategic decisions about which techniques to employ to fix the
image. Practice is the best path to becoming a skillful retoucher.
However, you can expect good results if you know which tools
to use. I have personally seen students become proficient using
Photoshop's rich suite of tools in just a few weeks.
Tip
Oversaturated Colors
If you sharpen a color photo and
you get oversaturated colors, switch
to the Lab image mode. Apply the
filter only to the Lightness channel.
Soft Focus
Cameras are much more likely to generate a soft focus under
low light. The Smart Sharpen filter has the most options of any
sharpening filter built into Photoshop. It allows you to choose the
sharpening algorithm as well as control the amount of sharpening
in shadow and highlight areas. This filter can produce dramati-
cally better quality, but do not expect results like you see in a TV
police drama.
1. Close any open files, open the Ch11_
Sharpen1.tif file, and zoom the document
window to 100%. This will give you the most
accurate view of the sharpening.
2. Choose Filter > Sharpen > Smart Sharpen
and select the Advanced radio button.
3. Click and drag the image in the preview win-
dow so you can better see the wood texture.
4. Adjust the controls in the Sharpen tab:
Amount. Sets the amount of sharpening.
A higher value increases contrast between
edge pixels, which gives the appearance
of more sharpness.
Radius. Determines the number of pixels
surrounding the edge pixels that will be
affected by the sharpening. A greater
radius value means that edge effects will
be more obvious, as will the sharpening.
