Adjusting The Brightness; Adjusting The Contrast - Canon CanoScan FB 1200S User Manual

Adjusting the Brightness

Adjusting the brightness is effective when the entire image is too bright or dark.
You must be careful, however, not to create excessive highlights or shadows by
setting the value to extreme levels.

Adjusting the Contrast

Contrast is the degree of difference between light and dark areas.
Raising the contrast accentuates the difference between light and
dark. Lowering it reduces the difference between the two.
Raising the contrast of blurred pictures is effective in adding clarity to
the image. Raising the contrast too high, however, will obscure the
dark portions or create excessive highlights.
