 Custom Function SettingsN

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.

Noise reduction is performed for all exposures of 1 sec. or longer. The 
[On] setting may be able to reduce noise which otherwise cannot be 
detected with the [Auto] setting.

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.
0: Standard

 

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 2, if a long exposure is shot with the Live View 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.)

 

With setting 2, the maximum burst for continuous shooting will greatly 
decrease.

 

If you playback a RAW or RAW+JPEG image with the camera or print an 
image directly, the effect of the high ISO speed noise reduction may look 
minimal. You can check the noise reduction effect or print noise-reduced 
images with Digital Photo Professional (provided software).
