You can correct the white balance that has been set. This adjustment 
will have the same effect as using a commercially-available color 
temperature conversion filter or color compensating filter. Each color 
can be corrected to one of nine levels.
This is for advanced users who are familiar with using color temperature 
conversion or color compensating filters.
1Select [WB Shift/BKT].
  Under the [ 2] tab, select [WB Shift/
BKT ], then press < 0>.
X The WB correction/WB bracketing 
screen will appear.
2Set the white balance correction.
  Press the < S> key to move the “ ” 
mark to the desired position.
  B is for blue, A is amber, M is 
magenta, and G is green. The color in 
the respective direction will be 
corrected.
  On the upper right, “ Shift” indicates 
the direction and correction amount.
  Pressing the < B> button will 
cancel all the [ WB Shift/BKT ] 
settings.
  Press < 0> to exit the setting and 
return to the menu.

 During the white ba lance correction,  will be displayed in the 
viewfinder and on  the LCD monitor.
  One level of the blue/amber  correction is equivalent to 5 mireds of a color 
temperature conversion filter. (Mir ed: Measuring unit indicating the 
density of a color temper ature conversion filter.)

With just one shot, three images  having a different color balance can be 
recorded simultaneously. Ba sed on the color temperature of the current white 
balance setting, the image will be br acketed with a blue/amber bias or 
magenta/green bias. This  is called white balance bracketing (WB-BKT). White 
balance bracketing 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 
 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 < B > button will cancel 
all the 
[WB Shift/BKT ] settings.
 Press < 0> to exit the setting and 
return to the menu.
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.
White Balance Auto Bracketing
B/A bias ±3 levels
During WB bracketing, the maximum burs t for continuous shooting will be 
lower and the number of possible shot s will also decrease to one-third the 
normal number.
  Since three images are recorded for one  shot, the card will take longer to 
record the shot.
  “BKT ” stands for Bracketing.

If the image comes out dark or the contrast is low, the brightness and 
contrast can be corrected automatic ally. 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).
The default setting is [ Standard].
1Select [Auto Lighting Optimizer].
 Under the [ 2] tab, select [Auto 
Lighting Optimizer ], then press 
< 0 >.
2Set the correction setting.
  Press the < U> key to select the 
desired setting, then press < 0>.
3Take the picture.
  The image will be recorded with the 
brightness and contrast corrected if 
necessary.

 Depending on the shoo ting conditions, noise might increase.
  If a setting other than [ Disable] is set and you use exposure 
compensation, flash expo sure compensation, or manual exposure to 
darken the exposure, the  image might still come out bright. If you want a 
darker exposure, set this to [ Disable] first.
In Basic Zone modes, [ Standard] is set automatically.

Due to the lens characteristics, the four corners of the picture might look 
darker. This is called lens light fall- off or drop in peripheral illumination. 
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).
The default setting is [ Enable].
1Select [Peripheral illumin. 
correct.].
 Under the [ 1] tab, select 
[Peripheral illumin. correct.], then 
press < 0>.
2Set the correction setting.
  On the screen, check that the 
attached lens’ [ Correction data 
available ] is displayed.
  If [Correction data not available] is 
displayed, see “About the Lens 
Correction Data” on the next page.
  Press the < V> key to select 
[Enable ], then press < 0>.
3Take the picture.
  The image will be recorded with the 
corrected peripheral illumination.

3 Lens Peripheral Illumination Correction
The camera already contains lens  peripheral illumination correction 
data for approx. 25 lenses. In step 2, if you select [ Enable], the 
peripheral light correction will be a pplied automatically for any lens 
whose correction data has been registered in the camera.
With EOS Utility (provided software), you can check which lenses have 
their correction data registered in the camera. You can also register the 
correction data for unregistered lens es. For details, see the Software 
Instruction Manual (CD- ROM) for EOS Utility.
About the Lens Correction Data
 For JPEG images already captured , lens peripheral illumination 
correction cannot be applied.
  Depending on shooting conditions , noise might appear on the image 
periphery.
  When using a non-Canon lens, setting the correction to [ Disable] is 
recommended, even if [ Correction data available] is displayed.
 Lens peripheral light co rrection is applied even when an Extender is 
attached.
  If the correction data for the attached  lens has not been registered to the 
camera, the result will be  the same as when the correction is set to 
[ Disable ].
  The correction amount applied will be  slightly lower than the maximum 
correction amount settable with Di gital Photo Professional (provided 
software).
  If the lens does not have distance in formation, the correction amount will 
be lower.
  The higher the ISO speed, the lowe r the correction amount will be.

The camera’s mechanical shake caused by the reflex mirror action can 
blur images taken with a super teleph oto lens or close-up (macro) lens. 
In such cases, mirror  lockup is effective.
Mirror lockup is enabled by selecting the [7  Custom Functions 
(C.Fn)] menu’s [Mirror lockup] and setting it to [1: Enable] (p.195).
1 Focus the subject, press th e shutter button completely.
XThe mirror will swing up.
2 Press the shutter button completely again.
XThe picture is taken and the mirror goes back down.
  Using the self-timer < l> with mirror lockup.
When you press the shutter button completely, the mirror locks up, 
then the picture is taken 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 prevent 
camera shake. With Remote Controller RC-6 set to a 2-sec. delay, 
press the transmit button, the mirr or will lockup and the picture will 
be taken 2 sec. later.
Preventing Camera Shake N
Shooting Tips
 Do not point the camera toward the su n. The sun’s heat can damage the 
camera’s internal components.
 
If you use the self-timer  and mirror lockup in combination with a bulb exposure, 
keep pressing the shutter but ton 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-rel ease sound, but no picture will be taken.
 Even if < i> (Continuous shooting) has been  set, single shooting will 
take effect.
  If 30 seconds elapse after the mirror  has locked up, it will go back down 
automatically. Pressing the  shutter button completely again locks up the 
mirror again.

Shooting with the LCD Monitor(Live View Shooting)
You can shoot while viewing  the image on the camera’s 
LCD monitor. This is called “Live View shooting.”
Live View shooting is effective for still subjects which do 
not move.
If you handhold the camera and shoot while viewing the 
LCD monitor, camera shake  can cause blurred images. 
Using a tripod is recommended.
About Remote Live View ShootingWith EOS Utility (provide d software) installed in your computer, you 
can connect the camera  to the computer and shoot remotely while 
viewing the computer screen. Fo r details, see the Software 
Instruction Manual  in the CD-ROM.

 When < g> is displayed in white, it indi cates that the Live View image 
brightness is close  to what the captured  image will look like.
  If  is blinking, it indicates that  the Live View image is not being 
displayed at the suitable  brightness due to low or bright light conditions. 
However, the actual im age recorded will reflect  the exposure setting.
  If flash is used or  bulb is set, the < g> icon and histogram will be 
grayed out (for your re ference). The histogram might not be properly 
displayed in low- or br ight-light conditions.
