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 you turn the < 5> 
dial, the “ ” mark on the screen will 
change to “     ” (3 points).
Turning the dial to the right sets the B/
A bracketing, and turning it to the left 
sets the M/G bracketing.
X On the right, “ Bracket” indicates the 
bracketing direction and correction 
amount.
  Pressing the < L> button will cancel 
all the [ WB Shift/Bkt. ] settings.
  Press < 0> to exit the setting.
 Bracketing Sequence
The images will be bracketed in the following sequence: 1. Standard 
white balance, 2. Blue (B) bias, and 3. Amber (A) bias, or 1. Standard 
white balance, 2. Magenta (M) bias, and 3. Green (G) bias.

 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 blink.
  You can change the sequence (p.483) and number of shots (p.484) for 
the white balance bracketing.
  “Bkt. ” stands for bracketing.

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 >.
2Select the setting.
  Select the desired setting, then press 
.
3Take the picture.
  The image will be recorded with the 
brightness and contrast corrected if 
necessary.
3 Auto Correction of Brightness and Contrast
  Depending on the shooting conditions, noise may increase.
  If the effect of Auto Lighting Optimizer is too strong and the image is too 
bright, set [ Low] or [Disable ].
  If a setting other than [ Disable] is set and y ou use exposure 
compensation or flash exposure compensation to darken the exposure, 
the image may still come out bright.  If you want a darker exposure, set 
this function to [ Disable].
  When you set multiple exposures (p.268), HDR mode (p.263), or 
highlight tone priority (p.206), [ Auto Lighting Optimizer] will be 
automatically set to [ Disable].
In step 2, if you press the < B> button and remove the [ X] mark for 
[ Disabled in M or B modes ] setting, the [Auto Lighting Optimizer ] can be 
set even in the < a> and < F> modes.

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>.
  M : Multi Shot Noise Reduction
This applies noise reduction wi th higher image quality than [High]. 
For a single photo, four shots  are taken continuously and aligned 
and merged automatically in to a single JPEG image.
If the image-recording quality is set to RAW or RAW+JPEG, you 
cannot set [ Multi Shot Noise Reduction ].
3Take the picture.
 The image will be recorded with noise 
reduction applied.

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 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 after 
performing 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 [z 3: Long exp. noise reduction ], [z 3: Multiple exposure ], [z 3: 
HDR Mode ], Dual Pixel RAW shooting, AEB shooting, WB bracketing, or 
Live View shooting with Servo AF is set, [ Multi Shot Noise Reduction] 
cannot be set.
  This cannot be set for bulb shooting.
  Flash shooting is not possible. Note that the AF-assist beam of EOS-
dedicated, external Speedlites will be emitted according to the [ 23: 
AF-assist beam firing ] setting.
  Doing any of the following will auto matically switch the setting to 
[ Standard ]: Setting the power switch to < 2>, replacing the battery, 
replacing the card, selecting the < A> or < F> shooting mode, setting or 
switching the image-recording quality to RAW or RAW+JPEG, or 
switching to movie shooting.

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 
.
  Auto
For exposures of 1 sec. or longer , noise reduction is performed 
automatically if noise typical of  long exposures is detected. This 
[ Auto ] setting is effective in most cases.
  Enable
Noise reduction is performed for all exposures of 1 sec. or longer. 
The [ Enable ] setting may reduce noise that cannot be detected with 
the [ Auto ] setting.
3Take the picture.
 The image will be recorded with noise 
reduction applied.

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 image 
displayed, “ BUSY” will be displayed during the noise reduction process. 
The Live View display will not appear until the noise reduction is 
completed. (You cannot take another picture.)

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.
3  Highlight Tone Priority
 When [ Enable ] is set, noise may increase slightly.
  With [ Enable ], the settable ISO speed range will start from ISO 200. 
Expanded ISO speeds cannot be set.
  When you set multiple exposures (p.268) or HDR mode (p.263), 
[Highlight tone priority ] will be automatically set to [ Disable].
When highlight tone is set, < A> is displayed in the viewfinder and on the 
LCD panel.

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 
characteristics of the lens, diffraction phenomenon, and the 
deterioration of resolution caused by the low-pass filter.
By default, the [ Peripheral illum corr ], [Chromatic aberr corr ], and 
[ Diffraction correction ] are set to [Enable], [Distortion correction ] 
and [ Digital Lens Optimizer ] is set to [Disable].
If the lens correction data is registered (saved) in the camera, 
peripheral illumination correction,  chromatic aberration correction, and 
diffraction correction will be done even in the < A> mode.
If the setting screen displays [ Correction data not available ] or the 
[ ] icon, it means that the correction  data for the respective lens is not 
registered in the camera. See “Lens Correction Data” on page 213.
1Select [Lens aberration 
correction].
 Under the [ z1] tab, select [ Lens 
aberration correction ], then press 
< 0 >.
2Select [Peripheral illum corr].

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 maximum 
correction amount that can be applied with Digital Photo Professional (EOS 
software, p.598).
