 Setting Noise ReductionN

132

Noise reduction is possible with images exposed for 1 sec. or longer.

 

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

 

If you are handholding the camera, keep it steady to prevent camera 
shake. If there is significant misalignment in the image due to camera 
shake, or if you are shooting a moving subject, the noise reduction effect 
may be minimal. Using a tripod is recommended.

 

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.

 

1

+73 or 1 cannot be selected. AEB shooting and WB bracketing 

cannot be used. [z3: Long exp. noise reduction] cannot be set. If any 
of these has already been selected or 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, change the shooting mode to a Basic Zone 
mode, shoot a bulb exposure, or shoot a movie, the setting will 
automatically be changed to [Standard].

 

[z3: Dust Delete Data] cannot be set. 

 

If you play back or directly print a 1+73 or 1 image with the camera, 
the effect of the high ISO speed noise reduction may look minimal. Check 
the noise reduction effect or print noise-reduced images with Digital Photo 
Professional (provided software, p.366).
