u White Balance Correction N
With just one shot, three images with different color tones can be 
recorded simultaneously. Based on the color temperature of the current 
white balance setting, the image will be bracketed with a blue/amber 
bias and magenta/green bias. This f unction is called white balance 
bracketing (WB-BKT). White balance br acketing is possible up to ±3 
levels in single-level increments.
Set the white balance bracketing 
amount.
 In step 2 for “White Balance 
Correction”, when...

 During white balance bracketing, the maximum burst for continuous 
shooting will be lower.
  Since three images are recorded for one shot, it takes longer to record 
the image to the card.
 You can also set white balance correction and AEB together with white 
balance bracketing. If you set AEB  in combination with white balance 
bracketing, a total of nine images  will be recorded for a single shot.
  When white balance bracketing is se t, the white balance icon will...

If the image comes out dark or the contrast is low, the brightness and 
contrast can be corrected automatical ly. This function is called Auto 
Lighting Optimizer. The default setting is [ Standard]. With JPEG 
images, the correction is applied when the image is captured.
In the < A> mode, [ Standard ] is automatically set.
1Select [Auto Lighting Optimizer].
 Under the [ z2] tab, select [ Auto 
Lighting Optimizer ], then press 
< 0 >.

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.
1Select [High ISO speed NR].
  Under the [ z3] tab, select [ High ISO 
speed NR ], then press < 0>.
2Set the level.
  Select the desired noise reduction 
level, then press < 0>.

Cautions for Setting Mult i 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...

For images exposed for 1 sec. or longer, noise (dots of light and 
banding) typical of long exposures can be reduced.
1Select [Long exp. noise 
reduction].
 Under the [ z3] tab, select [ Long 
exp. noise reduction ], then press 
< 0 >.
2Set the desired setting.
  Select the desired setting, then press

For exposures of 1 sec. or longer , noise reduction is performed 
automatically if noise typical of  long exposures is detected. This 
[ Auto ] setting is...

3 Setting Noise Reduction N
 With [ Auto] or [Enable ] set, the noise reduction process after the picture 
is taken may take the same amount of time as that for the exposure. 
During noise reduction, shooting is st ill possible as long as the maximum 
burst indicator in the viewfinder shows “1” or higher.
  Images taken at high ISO speeds may look grainier with the [ Enable] 
setting than with the [ Disable] or [Auto ] setting.
  With [ Enable ] set, if a long exposure is shot with the Live View...

You can reduce overexposed, clipped highlights.
1Select [Highlight tone priority].
 Under the [ z3] tab, select 
[ Highlight tone priority ], then press 
< 0 >.
2Select [Enable].
  Highlight details are improved. The 
dynamic range is expanded from the 
standard 18% gray to bright 
highlights. The gradation between the 
grays and highlights becomes 
smoother.
3Take the picture.
 The image will be recorded with 
highlight tone priority applied.

Peripheral light fall-off is a phenomenon that makes the image corners 
look darker due to the optical characteristics of the lens. Image 
distortion due to optical characteristics of the lens is called distortion. 
Color fringing along subject outlines  is called chromatic aberration. And 
decreased image sharpness due to the  aperture is called diffraction 
phenomenon. These lens aberrations can be corrected. The Digital 
Lens Optimizer can correct the variou s aberrations caused by optical...

3Select [Enable].
 Check that [ Correction data 
available ] is displayed for the 
attached lens.
  Select [ Enable], then press < 0>.
4Take the picture.
  The image will be recorded with the 
peripheral illumination corrected.
  Depending on shooting conditions, noise may appear on the image 
periphery.
  The higher the ISO speed, the lower the correction amount will be.
The correction amount applied will be slightly lower than the...
