Reduce “noise” (bright spots or fog) in photographs taken at slow shutter speeds.

Option

Description

[On]

Reduce noise in photographs taken at shutter speeds slower than 1 s.

[Off]

Long-exposure noise reduction disabled.

Long-exposure noise reduction is performed after the photo is taken. During processing, [Performing noise reduction] will appear in the shooting display. Pictures cannot be taken until the message has cleared from the display. The time required to process photos after shooting roughly doubles.

Long-Exposure Noise Reduction

If the camera is turned off before processing is complete, the picture will be saved but noise reduction will not be performed.
