Long Exposure Noise Reduction

Noise that tends to occur in long exposures at shutter speeds of one sec. or slower can be reduced.

  1. Select [Shooting: Long exp. noise reduction].

  2. 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.
  • buSY” is displayed as noise is reduced, and no Live View image is displayed until processing is finished, when you can shoot again.
