C.Fn II -1 Long exposure noise reduction

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 able to reduce noise which otherwise cannot be detected with the [Auto] setting.

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.)

C.Fn II -2 High ISO speed noise reduction

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	2:	Strong
1:	Low	3:	Disable

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).
