Follow steps 1 and 2 to turn off the AEB range display (set to 0).
 The AEB setting will also be canceled automatically if the power 
switch is set to < 2>, flash recycling is completed, etc.
 Using AEB with continuous shooting
If the drive mode is set to < i> or  (p.112) 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. The shooting will then stop 
automatically.
 Using AEB with single shooting ( u/B )
Press the shutter button three times to take the three bracketed 
shots. The three bracketed shots will be taken 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 control shooting (< Q> or ), 
you can take three continuous shots after a 10-sec. or 2-sec. delay. 
With  (p.114) set, the number of continuous shots will be three 
times the number set.

Shooting Tips
 During AEB, < A> in the viewfinder and AEB range will blink.
 AEB cannot be used with flash, [ Multi Shot Noise Reduction], Creative 
filters, or bulb exposures.
 If [z 2: Auto Lighting Optimizer ] (p.136) is set to any setting other 
than [ Disable ], the effect of AEB may be reduced.

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 picture. This is called AE lock. It is 
effective for backlit subjects, etc.
1Focus on the subject.
 Press the shutter button halfway.
 The exposure setting will be 
displayed.
2Press the  button. (0 )
 The < A> icon lights up in the 
viewfinder to indicate that the 
exposure setting is locked (AE lock).
 Each time you press the < A> button, 
the current autoexposure setting is 
locked.
3Recompose and take the picture.
 If you want to maintain the AE lock 
while taking more shots, hold down 
the < A> button and press the shutter 
button to take another shot.
* When the lens’s focus mode switch is set to < MF>, AE lock is applied to the 
center AF point.

Camera vibrations caused by the mirror’s reflex action is called “mirror 
shock”. Mirror lockup can reduce the  blur caused by camera vibrations.
This is useful especially when you  are using a super telephoto lens or 
shooting closeups (macro photography).
Mirror lockup is enabled by setting [9: Mirror lockup] to [1: Enable] 
in [ 54: Custom Functions (C.Fn)]  (p.342).
1 Focus on the subject, then press the shutter button 
completely.
 The mirror will swing up.
2 Press the shutter button completely again.
The picture is taken and the mirror goes back down.
 After taking the picture, set [ 9: Mirror lockup] to [0: Disable].
 Using the self-timer < Q>, < l> with mirror lockup
When you press the shutter button completely, the mirror locks up. 
The picture will be then taken 10 sec. or 2 sec. later.
 Remote control shooting
Since you do not touch the camera when the picture is taken, remote 
control shooting together with  mirror lockup can further reduce 
camera shake (p.350). With Remote Controller RC-6 (sold 
separately) set to a 2-sec. delay, press the transmit button to lock up 
the mirror, and the picture will be taken 2 sec. after the mirror lockup.

							Mirror Lockup to Reduce Camera ShakeK
164
Do not point the camera toward an intense light source, such as the sun 
or an intense artificial light source. Doing so may damage the image 
sensor or the camera’s internal components.
 In very bright light, such as at the beach or a ski slope on a sunny day, 
take the picture promptly afte r mirror lockup is stabilized.
 If you use the self-timer and bulb exposure in combination with a mirror 
lockup, keep pressing the shutter button completely (self-timer delay 
time + bulb exposure time). If you let go of the shutter button during the 
self-timer countdown, there will be  a shutter-release sound, but no 
picture will be taken.
 During mirror lockup, shooting function settings and menu operations, 
etc. are disabled.
 If you use flash, the red-eye reduction lamp will not light up (p.167).
Even if you set the drive mode to < i>, < M >, or < q>, the camera 
will still shoot in single shooting mode.
 When [ z3: High ISO speed NR ] is set to [Multi Shot Noise 
Reduction], four continuous shots will be taken for the single picture 
regardless of the [ 9: Mirror lockup] setting.
 If 30 sec. elapse after the mirror is locked up, it will go back down 
automatically. Pressing the shutter button completely again locks up the 
mirror again.

D Using the Built-in Flash
In bright light, decrease the ISO speed.
If the exposure setting in the viewfinder blinks, decrease the ISO 
speed.
 Detach the lens hood. Do not get too close to the subject.
If the lens has a hood attached or you are too close to the subject, 
the bottom of the picture may look dark due to the obstructed flash. 
For important shots, check the image on the LCD monitor to make 
sure the flash exposure looks natural (not dark at the bottom).
Using the red-eye reduction lamp  before taking a flash picture can 
reduce red eye.
Red-eye reduction will function  in any shooting mode except , 
, < 5>, < x>, or < G>.
Under the [ z1] tab, select [Red-eye 
reduc. ], then press < 0>.
 Select [ Enable], then press < 0>.
 For flash photography, when you 
press the shutter button halfway, the 
red-eye reduction lamp will light up. 
Then when you press the shutter 
button completely, the picture will be 
taken.
Shooting Tips
3  Red-eye Reduction
The red-eye reduction feature is more  effective when the subject looks at 
the red-eye reduction lamp, when the room is well lit, or when you are 
close to the subject.
 When you press the shutter button halfway, the 
scale display on the bottom of the viewfinder will 
shrink and turn off. For best  results, take the picture 
after this scale display turns off.
 The effectiveness of red-eye reduction varies depending on the 
individual subject.

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.
1Press the  button ( 7 ).
The Quick Control screen will appear 
(p.51).
2Select [ y].
Press the < S> cross keys to select 
[y *].
 [Flash exposure comp.] will be 
displayed at the bottom.
3Set the exposure compensation 
amount.
 If the exposure is too dark, turn the 
 dial to the right (for increased 
exposure).
If the exposure is too bright, turn the 
< 6 > dial to the left (for decreased 
exposure).
 When you press the shutter button halfway, the < y> icon will 
appear in the viewfinder.
 After taking the picture, cancel the flash exposure 
compensation by setting it back to 0.
y  Flash Exposure Compensation K
If [z 2: Auto Lighting Optimizer ] (p.136) is set to any setting other 
than [ Disable ], the image may still look br ight even if a decreased flash 
exposure compensation is set.

If flash exposure compensation is set with an external Speedlite (sold 
separately, p.171), you cannot set the flash exposure compensation with the 
camera (Quick Control or External flash function settings). If it is set with both 
the camera and Speedlite, the Speedlite’s setting overrides the camera’s.

D Using the Built-in Flash
If the subject is on the side of the frame and you use flash, the subject may 
turn out to be too bright or dark depending on the background, etc. Use FE 
lock in such a case. After setting the proper flash exposure for the subject, 
you can recompose (put the subject toward the side) and shoot. This 
feature can also be used with a Canon EX-series Speedlite.
* FE stands for Flash Exposure.
1Press the  button.
The built-in flash will be raised.
