 Noise Reduction SettingsN

You can reduce noise in long exposures.

 

Under the [z3] tab, select [Long 
exp. noise reduction], then press 
<0>.

 

The following functions cannot be set: AEB, WB bracketing, [z3: Long 
exp. noise reduction], 1+73/1. If any of these has already been 
set, [Multi Shot Noise Reduction] cannot be set.

 

Flash shooting is not possible. The AF-assist beam will be emitted according to 
the [54: Custom Functions (C.Fn)]’s [4: AF-assist beam firing] setting.

 

You cannot set [Multi Shot Noise Reduction] for bulb exposures.

 

If you turn off the power or change the shooting mode to a Basic Zone 
mode, movie shooting, or bulb, the setting will change to [Standard].

 

If there is significant misalignment in the image due to camera shake, the 
noise reduction effect may be minimal.

 

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 subject’s movement may leave 
afterimages or the surrounding area of the subject may become dark.

 

The image alignment may not function properly with repetitive patterns 
(lattice, stripes, etc.) or flat, single-tone images.

 

Recording the image to the card will take longer than with normal 
shooting. During the processing of the images, “BUSY” will be displayed 
and you cannot take another picture until the processing is completed.

 

[z3: Dust Delete Data] cannot be set.

 

If [Multi Shot Noise Reduction] is set, direct printing (p.280) is not 
possible.
