102 Microtek ScanWizard Pro for Mac OS X
Filter tool (LCH & Native color mode)
The Filter tool is used to apply special effects to your images. Several filters are
provided in ScanWizard Pro, including Blur / Blur More, Sharpen / Sharpen
More, Emboss, Edge Enhancement, Gaussian Blur, and Unsharp Masking.
In using most of the Filters (except Unsharp Masking), the image you obtain in
the preview window may differ from the way the image appears when you
finally scan it in. For the Unsharp Masking filter, the final scan result can be
simulated and previewed, either from the thumbnail on the filters dialog box or
from the preview image in the Preview window.
Keep in mind too that the appearance of the image in the preview window and
how it is affected by a filter will depend on the resolution of the image. The
higher the resolution, the less obvious the effect of certain filters (such as Blur).
Check this box to apply
the filter effect to the
Lightness "L" channel (for
LCH mode only)
Check this box to
ensure that for the
Unsharp Masking
filter, the image
displayed in the
preview window
simulates that of the
final scan
