0:Off
1:Auto
For 1 sec. or longer exposures, noise reduction is performed automatically if noise typical of long exposures is detected. This [Auto] setting is effective in most cases.
2:On
Noise reduction is performed for all exposures of 1 sec. or longer. The [On] setting may be effective for noise that cannot be detected or reduced with the [Auto] setting.
With settings 1 and 2, the continuous shooting speed will be slower even with shutter speeds faster than 1 sec. (with the
With settings 1 and 2, after the picture is taken, the noise reduction process may take the same amount of time as the exposure. You cannot take another picture until the noise reduction process is completed.
At ISO 1600 and higher, noise might be more pronounced with setting 2 than with setting 0 or 1.
With setting 1 or 2, if a long exposure is shot with the Live View image displayed, “BUSY” will be displayed during the noise reduction process. The Live View display will not appear until the noise reduction is completed. (You cannot take another picture.)
Reduces the noise generated in the image. Although noise reduction is applied at all ISO speeds, it is particularly effective at high ISO speeds. At low ISO speeds, the noise in the shadow areas is further reduced. Change the setting to suit the noise level.
