SCANNER SETUP OPTIONS
This window provides access to scanner-specific settings.
Photo Invert
Selecting this control will let you scan the “negative” of your images.
Horizontal Mirror
This option allows you to do a scan which mirrors the image over a vertical axis
down the center of the image, thus reversing the image left-to-right. Note that in
portrait mode, this axis cuts through the narrower sides, while in landscape
mode, it cuts through the wider sides.
Dithering
Dithering can help make a black-and-white scan represent gray images. It does
this by varying the size of clusters of black pixels. When viewed at arm’s length,
the dots blur, and the resulting image appears to have gray tones.
The larger the pattern area, the more gray levels that can be represented, but with
a grainier result. Dither patterns can also be downloaded to achieve special
effects.
