Other advanced scanning features include:
Scanning Filters
Automatically adjusts image quality
based on the type of original
scanned.
Resolution
Changing resolution can also affect
the clarity of an image.
Using AutoExposure
The AutoExposure tool checks the scan image for the
brightest and darkest points, and sets the highlight and
shadow points according to a preset formula. It also
adjusts the midtones (tones between extreme bright
and dark) to align with the extreme points for an overall
brighter image.
AutoExposure can be used for color or grayscale
images. It is not needed for line art (1-bit scan mode).
To activate AutoExposure, click the AutoExposure
button .
