8 - 3
E - Exposure
Exposure is used in Manual Style only (2P), and allows you to set the expo-
sure time. This is similar to setting a shutter speed on a camera. The
exposure time determines how long the scanner takes to record an image.
On a bright day, exposure times can be very short because plenty of light is
available to help record an image. At nighttime, exposure time can increase
dramatically due to the near absence of light. Units are 127 microseconds.
(Default = 7874)
nE Range: 1 - 7874
G - Gain
Gain is used in Manual Style only (2P). Like a volume control, the gain
modifier boosts the signal and multiplies the pixel value. As you increase
the gain, the noise in an image is also amplified.
1G No gain (default)
2G Medium gain
4G Heavy gain
8G Maximum gain
