Zenith Weighted Metering - With zenith weighted metering, the camera will
use the light information coming from above the scanner to determine its
exposure setting. Use this mode if there is very bright light coming from
windows or other sources, and if you want to achieve the most correct balance
of light and exposure for objects at the ceiling of building (e.g., for ceiling
paintings in historical buildings). Compared to even weighted metering, this
mode will increase scan duration by approximately 14 seconds.

HDR Mode
The High Dynamic Range (HDR) imaging method merges images captured
with different exposure settings to one image with a greater dynamic range of
luminosity.
Scanning with HDR
capturing
Set the HDR capturing by tapping the + or - button from 2x to 5x. This setting
corresponds to the exposure levels. Typically, settings from 2x, 3x or 5x are
sufficient for most applications. Choose OFF to disable HDR.
