Shooting
How to adjust the exposure
This camera automatically adjusts the exposure to shoot
images with the optimal brightness. However, recorded
images may sometimes be brighter or darker than the actual
image depending on the shooting conditions. If this
happens, adjust the exposure compensation manually.
Underexposure
The whole recorded image is dark,
which makes white elements of the
image appear gray. Shooting bright
subjects or in backlit conditions may
cause the image to be underexposed.
Adjust the exposure compensation
towards the + end.
Optimal Exposure
Overexposure
