Exposure Adjustment
REC AUTO mode
The exposure time set by AE (Auto Exposure) can be corrected (by up to
2 EV in 1/3 EV steps).
When the specimen is dark, +EV correction will extend the exposure time
and give an over-exposure type effect. When it is bright, the -EV correc-
tion will shorten the exposure time and give an under-exposure type
effect.
Press the cursor button @ or ² to set the exposure adjustment
value. The setting can be checked on the following scale at the bottom
of the INFO display.
}Switch off the MENU display before the exposure adjustment. If the MENU
display is shown, press the MENU button on the hand switch D21-HS to
hide it.
