Description
Using Long Exposure Noise Reduction to reduce noise in longer exposures on the EOS 1Dx Mark III.
Solution

Long Exposure Noise Reduction
Long Exposure Noise Reduction
Noise that tends to occur in long exposures at shutter speeds of one sec. or slower can be reduced.
-
Select [ : ].
-
Set a reduction option.
-
Auto
For images exposed for 1 sec. or longer, noise reduction is performed automatically if noise typical of long exposures is detected. This setting is effective enough in most cases.
-
Enable
Noise reduction is performed for all images exposed for 1 sec. or longer. The [Enable] setting may reduce noise that cannot be detected with the [Auto] setting.
Caution
- With [Auto] or [Enable] set, noise reduction after you shoot may take as long as exposure for the shot.
- Images may look grainier with the [Enable] setting than with the [Disable] or [Auto] setting.
- “
 ” is displayed as noise is reduced, and no Live View image is displayed until processing is finished, when you can shoot again.
