Controls tab
The Controls tab of the HP PrecisionScan Pro
Preferences dialog box has option buttons for
selecting which control range readout to use for
scanning.
The control range sets the amount of tonal
resolution per color available for correction in the
Exposure Adjustment and Black & White Threshold
tools. Using a larger number of bits for the control
range results in greater control of compensation
for exposure or threshold correction.

8 bits of tonal resolution per color

➌
