High ISO Speed Noise Reduction
This function reduces the noise generated in the image. Although noise
reduction is applied at all ISO speeds, it is particularly effective at high
ISO speeds. When shooting at low ISO speeds, the noise in the darker
parts of the image (shadow areas) can further be reduced. Change the
setting to match the noise level.
[M: Multi Shot Noise Reduction]

For a single photo, four shots are taken continuously and aligned
and merged automatically into a single JPEG image.
If the image-recording quality is set to 1 or 1+73, you cannot
set [Multi Shot Noise Reduction].
You can set the camera to display <i> in the viewfinder for when Multi Shot
Noise Reduction is set (p.395).
