Setting Noise Reduction
N
144
With [
Auto
] and [
Enable
], the noise reduction process after the picture is
taken may take the same amount of time as that for the exposure.
Shooting is disabled when noise reduction is performed.
Images taken at ISO 1600 or higher may look grainier with the [
Enable
]
setting than with the [
Disable
] or [
Auto
] setting.
