Long Exposure Noise Reduction Options (Noise Reduction)

Choose whether to process photos taken at slow shutter speeds to reduce image artifacts (“noise”). At slow shutter speeds, noise is caused by the heat generated from the camera itself. After each photo is taken, the camera captures a second image for noise reduction, causing a delay equal to the selected shutter speed before the next photo can be taken.

Off	Noise reduction not performed.
On	Noise reduction is performed at all shutter speeds.
Auto	Noise reduction is performed automatically when the camera’s internal temperature is elevated.

• During noise reduction, the camera displays the time remaining until the process is complete.
• During sequential shooting, [Off] is selected automatically and noise reduction is not performed.
• Noise reduction may not produce the desired effects depending on the subject and shooting conditions.
• To use this function in silent mode, it is required that you configure the [Silent I Settings] setting (“Shooting without shutter sound (Silent I Settings)”).
