How to read the level meter
The level meter is displayed in the following screens:
 [CAMERA MENU: CAMERA]
 [CAMERA MENU: SHOT/REC]
 [CAMERA MENU: IMAGE]
The [LEVEL] meter shows the exposure condition.
The meter consists of 12 elements: four in the green zone
(center), four in the red zone (right), and four in the blue zone
(left). The elements to be lit change according to the exposure
level.
Four elements are always lit. When the exposure level is
correct, the four elements in the green zone (center) are lit.
The position of the lit elements moves to the right as exposure
increases, and to the left as exposure decreases. To change the
exposure compensation value, tap the [EXP CMP] button.
