Brightness

Adjust this settings (-50 to 50) to obtain the best image. The default
value is 0, representing an 'average'.
You can set the level by dragging the slidebar to the right or left to
lighten or darken the image. You can also type a value in the box for
the setting.
If the scanned image is too light, set a lower brightness value and
scan the document again. If the image is too dark, set a higher
brightness value and scan the document again.

Contrast

This setting is adjustable only when you have selected one of the
grey scale settings. It is not available when Black & White and colour
setting are selected as the Scan Type.
You can increase or decrease the contrast level by moving the
slidebar to the left or right. An increase emphasizes dark and light
areas of the Image, while a decrease reveals more detail in grey
areas. You can also type a value in the box for the setting.
Set the Scan Type to Black & White for text or line
art.
Set the Scan Type to Grey or True Grey for
photographic images.
Set either:
256 Colour, which scans up to 256 colours, or
24 bit Colour which scans up to 16.8 million
colours.
Although using 24 bit Colour creates an image with
the most accurate colours, the image file will be
approximately three times larger than a file created
with 256 Colour.
