Determines if the LEDs should be on or off, and when. Ambient illumination (0L)
is preferred for taking pictures of color documents, such as ID cards, especially
when the scanner is in a stand. LED illumination (1L) is preferred when the

E - Exposure
Exposure is used in Manual Style only (2P), and allows you to set the exposure
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.
