Four methods (metering modes) to measure the subject’s brightness 
are provided. Normally, evaluative metering is recommended.
In Basic Zone modes, evaluative metering is set automatically.
1Select [Metering mode].
Under the [A 3] tab, select 
[Metering mode ], then press .
2Set the metering mode.
Select the metering mode, then press 
.
q Evaluative metering 
This is a general-purpose metering mode suited 
even for backlit subjects. The camera sets the 
exposure automatically to suit the scene.
w  Partial metering
Effective when the background is much brighter 
than the subject due to backlighting, etc. The 
gray area in the left figure is where the 
brightness is metered to obtain the standard 
exposure.
r  Spot metering
This is for metering a specific part of the subject 
or scene. The gray area in the left figure is 
where the brightness is metered to obtain the 
standard exposure. This metering mode is for 
advanced users.

e Center-weighted average metering
The brightness is metered at the image center 
and then averaged for the entire scene. This 
metering mode is for advanced users.
When One-Shot AF is set: With  q, the exposure setting will be locked 
when you press the shutter button halfway and focus is achieved. With  w, 
r , and  e, the exposure setting is set at the moment of exposure. (The 
exposure setting is not locked when you press the shutter button halfway.)

Set exposure compensation if the exposure (without flash) does not come out 
as desired. This feature can be used in Creative Zone modes (except <
a>). 
You can set the exposure compensation up to ±3 stops in 1/3-stop increments.
You can set exposure compensation on the Live View screen or  B 
Quick Control screen. On the Live View screen, you can adjust the 
exposure compensation while checking the effect on the screen.
Using the Live View screen When you tap the exposure 
compensation scale, the setting 
screen appears. Tap [ +]/[- ] to adjust 
the exposure compensation.
Using the  B Quick Control screenOn the B Quick Control screen, select 
exposure compensation. Either tap [
+]/[-] 
or press the <
Y A>/ button to 
adjust the exposure compensation.
 Making it brighter:
Tap [ +] or press the < ZO > button. 
(Increased exposure)
 Making it darker:
Tap [ -] or press the < YA > button. 
(Decreased exposure)

After taking the picture, cancel the exposure 
compensation by setting it back to 0.

If you combine it with AEB (p.155), you can set it beyond ±3 stops. Set it 
with [ A3: Expo.comp./AEB ] or the B Quick Control screen.

Set flash exposure compensation if the flash exposure of the subject does not come out 
as desired. You can set the exposure compensation up to ±2 stops in 1/3-stop increments.
1Display the B Quick Control 
screen.
2Select [ y].
Press the < Wj /i >//
< Y A >/ button to select [y *].
[Flash exposure comp. ] will be 
displayed at the bottom.
3Set the exposure compensation amount.
To make the flash exposure brighter, turn the 
<
5> dial to the right. (Increased exposure)To make it darker, turn the  dial 
to the left. (Decreased exposure)
 Alternatively, you can press < Q/
0 > to display the setting screen. 
Tap [ Y]/[Z ] or turn the 
 dial to 
adjust the compensation amount.
When you tap [ 2], the  icon will 
appear.

After taking the picture, cancel the flash 
exposure compensation by setting it back to 0.
y  Flash Exposure  Compensation
If [A 3: Auto Lighting Optimizer ] (p.159) is set to any setting other than 
[ Disable ], the image may look bright even if a decreased exposure 
compensation or decreased flash exposure compensation is set.
You can also set flash exposure compensation with [ Flash function 
settings ] in [A1: External Speedlite control ] (p.222).

This feature takes exposure compensation a step further by varying the 
exposure automatically (up to ±2 stops in 1/3-stop increments) with 
three shots as shown below. You can then choose the best exposure.
This is called AEB (Auto Exposure Bracketing).
1Display the B Quick Control 
screen.
2Select exposure compensation.
3Set the AEB range.
 Turn the  dial or tap [ ]/[ ] to 
set the AEB range.
 You can also set both AEB and 
exposure compensation. Either tap 
[+]/[-] or press the < YA >/< ZO > 
button to adjust the AEB range 
centering on exposure compensation 
setting.
 After you exit the setting, the AEB 
range will appear on the LCD monitor.

4Take the picture.
Press the shutter button completely. 
The three bracketed shots will be 
taken in this sequence: standard 
exposure, decreased exposure, and 
increased exposure.
 Follow steps 1 to 3 to turn off the AEB level display.
 The AEB setting will also be canceled automatically if the power is 
set to < 2>, flash recycling is completed, etc.
 Using AEB with continuous shooting
If  continuous shooting (p.133) is set and you press the shutter 
button completely, the three bracketed shots will be taken 
continuously in this sequence: standard exposure, decreased 
exposure, and increased exposure.
 Using AEB with < u> single shooting
Press the shutter button three times to ta ke the three bracketed shots. 
The three bracketed shots will be exposed in the following sequence: 
standard exposure, decreased exposure, and increased exposure.
Using AEB with the self-timer or a Remote Controller (sold separately)With the self-timer or a Remote Controller (< Q> or < l>), you can 
take three continuous shots after a 10-sec. or 2-sec. delay. With 
< q > (p.136) set, the number of continuous shots will be three 
times the number set.
Canceling AEB
Shooting Tips
AEB can also be set with the [ A3] tab’s [Expo.comp./AEB ].
AEB cannot be used with flash, Multi Shot Noise Reduction, Creative 
filter shooting, and bulb shooting.
 If [A 3: Auto Lighting Optimizer ] (p.159) is set to any setting other 
than [ Disable ], the AEB’s effect may be minimal.

You can lock the exposure when the area of focus is to be different from 
the exposure metering area or when you want to take multiple shots at 
the same exposure setting. Press the  button to lock the 
exposure, then recompose and take the shot. This is called AE lock. It is 
effective for backlit subjects.
1Focus the subject.
 Press the shutter button halfway.
The exposure setting will be 
displayed.
2Press the  button. (8 )
 will appear and the exposure 
will be locked (AE lock).
 Press the < YA > button again to 
cancel the AE lock.
3Recompose and take the picture.
 If you want to maintain the AE lock 
while taking more shots, hold down 
the < YA > button and press the 
shutter button to take another shot.

If the image comes out dark or the contrast is low, the brightness and 
contrast can be corrected automatically. This function is called Auto 
Lighting Optimizer. The default setting is [Standard]. With JPEG 
images, the correction is done when the image is captured. For RAW 
images, it can be corrected with Digital Photo Professional (provided 
software, p.340).
In Basic Zone modes, [Standard ] is set.
1Select [Auto Lighting Optimizer].
Under the [A 3] tab, select [Auto 
Lighting Optimizer ], then press .
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 ContrastN
 Under [ 54: Custom Functions (C.Fn) ], if [3: Highlight tone priority ] is 
set to [1: Enable ], the Auto Lighting Optimizer will be set automatically to 
[ Disable ] and the setting cannot be changed.
 Depending on the shooting conditions, noise may increase.
 If a setting other than [ Disable] is set and you 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].
In step 2, if you press the < B> button and uncheck < X> the [ Disable 
during man expo ] setting, the Auto Lighting Optimizer can be set in the 
< a > mode.

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. At low ISO speeds, the noise in the darker parts of the 
image (shadow areas) is further reduced. Change the setting to suit the 
noise level.
1Select [High ISO speed NR].
Under the [A 4] tab, select [High 
ISO speed NR ], then press .
2Set the setting.
Select the desired setting, then press 
.
The setting screen closes and the 
menu will reappear.
 [Multi Shot Noise Reduction]
Noise reduction with higher image quality than when [ High] is 
applied. For a single photo, four shots are taken in a burst and 
merged automatically into a single JPEG image.
3Take the picture.
 The image will be recorded with noise 
reduction applied.
3  Noise Reduction Settings N
High ISO Speed Noise Reduction
With [High] or [ Multi Shot Noise Reduction ], the maximum burst for 
continuous shooting will greatly decrease.
