Compensating the exposure
You can compensate the exposure time specified automatically. (The
exposure can be compensated in the range between -2EV and +2EV
in increments of 1/3EV.)
When acquiring a dark specimen, perform "+ compensation" to make
the exposure time longer to bring the overexposed effect. When
acquiring a bright specimen, perform "- compensation" to make the
exposure time shorter to bring the underexposed effect.
Select the [Acquisition] tab

· If you want to reduce the exposure time without darkening the
image, use [Gain]
G
. The [Gain] value is multiplied by the
intensity value. Using [Gain] allows you to brighten the entire
image and reduce the exposure time, but the noise in the
image is enhanced.
