counter-clockwise - This option will only appear when
scanning transparencies or negatives, if your scanner is built with a
transparency adapter.
It will rotate the scanned image 90

only affect the final scanned image.
Prescan Window -
The Prescan Window (figure 2) is the large white area in the
middle of the TWAIN window. Documents or images that are prescanned will
be displayed there.
Prescanning images is very useful as it gives you an idea of how a document or
image will look after it is scanned. You can use the Magnifying Glass to zoom
the view of the prescanned image by clicking on the magnifying glass button
towards the upper right of the TWAIN window and then clicking on the part of
the image you wish to view in detail.
Figure 2. Prescan Window
If you change any settings either in the TWAIN window or in any of the
Advanced windows, the effects of the changes (except for Flip, Rotate, Filter
and Descreen) will immediately appear on the prescanned image in the Prescan
Area. This allows you to instantly judge the effects of almost any setting you
change.
The Scan Area Border, designated by the dotted box in the Prescan Area, can
be resized and moved. This is very important for keeping the image size (in
terms of computer memory) as small as possible. To do this, first prescan the
document or image you wish to scan by loading it in the scanner and clicking
on the Prescan Button. After it appears in the Prescan Area, resize and move
the dotted box so it fits snugly around the edges of the prescanned image.
