Brightness; Color Mode - Epson ActionScanner II User Manual

Brightness

You can choose one of seven brightness levels for scanning.
Medium is the normal setting.
It is better to use darker settings for line art or faint original
images, and to use lighter settings for darker original images.
The brightness can be combined with any other function.
The graph below shows the differences between the brightness
settings when the gamma correction is set for the CRT Display A
setting.
