Miscellaneous
Brightness
Adjust the brightness settings to obtain the best image. The Brother TWAIN
Scanner driver offers 100 brightness settings (-50 to 50). The default value is 0,
representing an “average” setting.
You can set the brightness level by dragging the slidebar to the right to lighten
the image or to the left to darken the image. You can also type a value in the box
to set the setting. Click OK.
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
The contrast setting is adjustable only when you have selected one of the gray
scale settings, but it is not available when Black & White is selected as the Gray
Scale.
Increasing the contrast level (by dragging the slidebar to the right) emphasizes
dark and light areas of the Image, while decreasing the contrast level (by
dragging the slidebar to the left) reveals more detail in gray areas. Instead of
using the slidebar, you can type a value in the box to set the contrast. Click OK.
