When you shoot in manual adjustment mode, we recommend you to keep the exposure
fixed to make a clear picture. This section shows you what the exposure is and how to
adjust each item with the exposure fixed.
Understanding the exposure
Exposure is determined by aperture, shutter speed and gain, and is measured in EV
(exposure value) as shown below.
Total EV = EV from aperture control
+ EV from shutter speed control
+ EV from gain control
The total exposure value can be varied or maintained at a constant level by controlling
the aperture, gain and shutter speed.
Use the following graph to select the setting. One scale corresponds to 0.5 EV.
