The first series of this article was in the August issue. It covered what to look for in a scanner and basic image adjustments. This article will cover additional things you can do to enhance the image using Adobe Photoshop. Since a flat-bed scanner scans a little soft, you may need to add sharpness to the design. It also increases the dark edges and lightens the light edges.
Most images can use a small amount of sharpening.
The Unsharp Mask Filter has three settings. A good Radius in Pixels setting is 1 to 1.5 and a Threshold value of 5 to 10 will be sufficient. This means you can oversharpen slightly and it will not be noticeable in the final print. Don t be afraid to go to extremes here. Your scanner may actually apply a slight hue error to the image.
