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, “lm” will flash in the control panel and viewfinder. Pictures cannot be taken until the display stops flashing. 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.
