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