3 Setting Noise ReductionN
Cautions for Setting Multi Shot Noise Reduction
 If there is significant misalignment in the image due to camera shake, the
noise reduction effect may become smaller.
 If you are handholding the camera, keep it steady to prevent camera
shake. Using a tripod is recommended.
 If you shoot a moving subject, the moving subject may leave
afterimages.
 The image alignment may not function properly with repetitive patterns
(lattice, stripes, etc.) or flat, single-tone images.
 If the subject’s brightness changes as the four consecutive shots are
taken, irregular exposure in the image may result.
 After shooting, it may take some time to record an image to the card for
noise reduction and merging the images. During the processing of the
images, “buSY” will be displayed in the viewfinder and on the LCD panel,
and you cannot take another picture until the processing is completed.
 You cannot use AEB and WB bracketing.
 If [z3: Long exp. noise reduction], [z3: Multiple exposure], [z3:
HDR Mode], AEB, or WB bracketing is set, [Multi Shot Noise
Reduction] cannot be set.
 You cannot set [Multi Shot Noise Reduction] for bulb exposures or
movie shooting.
 Flash shooting is not possible. The AF-assist beam will be emitted
according to the [8 C.Fn II -6: AF-assist beam firing] setting.
 If you turn off the power, change the shooting mode to a Basic Zone
mode or <F>, or switch to movie shooting, the setting will automatically
switch to [Standard].
