Long Exposure Noise Reduction
For images exposed for 1 sec. or longer, noise (dots of light and banding)
typical of long exposures can be reduced.
1
Select [z: Long exp. noise
reduction].
2
Set a reduction option.
z
[AUTO] Auto
For exposures of 1 sec. or longer, noise reduction is performed
automatically if noise typical of long exposures is detected. This [Auto]
setting is effective enough in most cases.
z
[ON] Enable
Noise reduction is performed for all exposures of 1 sec. or longer. The
[Enable] setting may reduce noise that cannot be detected with the
[Auto] setting.
z
With [Auto] or [Enable] set, the noise reduction process after the picture is
taken may take the same amount of time as that for the exposure.
z
Images may look grainier with the [Enable] setting than with the [Disable] or
[Auto] setting.
z
[BUSY] is displayed as noise is reduced, and the shooting screen is not
displayed until processing is îš¿nished, when you can shoot again.
