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, the message, “[Performing noise reduction]” will appear in the shooting display and “Job NR” will flash in the control panel. Pictures cannot be taken until the message has cleared from the display. The time required to process photos after shooting roughly doubles.
