3 White Balance Correction N
With just one shot, three images having a different color tone 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 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 <
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.
XOn the right side of the screen, “BKT”
indicates the bracketing direction and 
the bracketing amount is also displayed.
 Pressing the  button will cancel 
all the [
WB SHIFT/BKT] settings.
 Press  to exit 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, 3. Green (G) bias.
White Balance Auto Bracketing
B/A bias ±3 levels
 During WB bracketing, the maximum burst for continuous shooting will be 
lower and the number of possible shots will also decrease to one-third the 
normal number. Also, the white balance icon will blink on the LCD panel.
  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.
  Since three images are recorded for one shot, the CF card will take 
longer to record the shot.
  “BKT ” stands for Bracketing.

The file number is like the frame number on a roll of film. The captured 
images are assigned a sequential file number from 0001 to 9999 and 
saved in one folder. You can also change how the file number is 
assigned.
The file number will appear on the personal computer in this format: 
IMG_0001.JPG.
1Select [File numbering].
 Under the [ 5] tab, select [ File 
numbering ], then press < 0>.
2Select the file numbering method.
  Turn the < 5> dial to select the 
desired method, then press < 0>.
File numbering continues even after CF card replacement
Even after you replace the CF card, the file numbering continues in 
sequence up to 9999. This is convenient when you want to save the 
images numbered anywhere between 0001 to 9999 in one folder in your 
personal computer.
If the replacement CF card contains images recorded previously, the file 
numbering of the new images might continue from the file numbering of 
the existing images in the card. If you want to use continuous file 
numbering, you should use a newly-formatted CF card each time.

3 File Numbering Methods
Resets the file numbering to 0001 whenever the CF card is replaced
Each time the CF card is replaced, the file numbering starts from 0001. 
This is convenient if you want to organize images according to CF cards.
If the replacement CF card contains images recorded previously, the file 
numbering of the new images might continue from the file numbering of 
the existing images in the card. To start the file numbering from 0001, the 
CF card must be formatted before use.
The file numbering starts from 0001 in the new folder
When you reset the file numbering manually, a new folder is created 
automatically and the file numbering of images saved to that folder 
starts from 0001. This is convenient when you want to use different 
folders for the images taken yesterday and the ones taken today, for 
example. After the manual reset, the file numbering returns to 
continuous or auto reset.

If folder No. 999 is created, [ Folder number full] will appear on the LCD 
monitor. If that folder contains images reaching file number 9999, shooting 
will not be possible even if the CF card still has storage capacity. The LCD 
monitor will display a message to replace the CF card. Be sure to replace 
the CF card.
For both JPEG and RAW/sRAW images, the file name will start with “IMG_”. 
The extension will be “.JPG” for JPEG images and “.CR2” for RAW and 
sRAW images.

The color space refers to the range of reproducible colors. With this 
camera, you can set the color space for captured images to sRGB or 
Adobe RGB. For normal images, sRGB is recommended.
1Select [Color space].
 Under the [ 2] tab, select [ Color 
space ], then press < 0>.
2Set the desired color space.
  Select [ sRGB] or [Adobe RGB ], then 
press < 0>.
This is mainly used for commercial printing and other industrial uses. 
This setting is not recommended if you do not know about image 
processing, Adobe RGB, and Design rule for Camera File System 2.0 
(Exif 2.21). Since the image will look very subdued with sRGB personal 
computer environment and printers not compatible with Design rule for 
Camera File System 2.0 (Exif 2.21), post-processing of the image with 
software will be required.
3  Setting the Color Space N
About Adobe RGB
 If the captured image was shot in the Adobe RGB color space, the first 
character in the file name will be an underscore “_”.
 
The ICC profile is not appended. The ICC profile is explained in the 
Software Instruction Manual (CD-ROM).

f: Selecting the AF Mode N
This AF mode is for moving subjects when the focusing distance 
keeps changing. While you hold down the shutter button halfway, 
the subject will be focused continuously.
 The exposure is set at the moment the picture is taken.
  In the Creative Zone modes, AF is also possible by pressing the 
 button.
  When the AF point selection is automatic (p.78), the camera first 
uses the center AF point to focus. During autofocusing, if the subject 
moves away from the center AF point, focus tracking continues as 
long as the subject is covered by another AF point.
AI Focus AF switches the AF mode from One-Shot AF to AI Servo 
AF automatically if the still subject starts moving.
  After the subject is focused in the One-Shot AF mode, if the subject 
starts moving, the camera will detect the movement and change the 
AF mode automatically to AI Servo AF.
AI Servo AF for Moving Subjects
AI Focus AF for Automatic  Switching of AF Mode
 If focus cannot be achieved, the focus confirmation light < o> in the 
viewfinder will blink. If this occurs, a picture cannot be taken even if the 
shutter button is pressed completely. Recompose the picture and try and 
focus again. Or see “When Autofocus Fails” (p.80).
  If the [ 1Beep ] menu is set to [ Off], the beeper will not sound when 
focus is achieved.
With AI Servo AF, the beeper will not sound even when focus is achieved. 
Also, the focus confirmation light < o> in the viewfinder will not light.
When focus is achieved in the AI Focus AF mode with the Servo mode 
active, the beeper will sound softly. The focus confirmation light < o> in the 
viewfinder will not light.

Under low-light conditions, when you press the shutter button halfway, 
the built-in flash fires a brief burst of flashes. It illuminates the subject to 
enable easier autofocusing.
With lenses whose maximum aperture is larger than f/5.6
With all AF points, cross-type AF sensitive to both vertical and 
horizontal lines is possible.
With lenses whose maximum aperture is larger than f/2.8*
With the center AF point, high-precision, cross-type AF sensitive to both 
vertical and horizontal lines is possible. The center AF point’s sensitivity 
to vertical and horizontal lines is about twice as sensitive as the other 
AF points.
The remaining eight AF points will work as cross-type points with lenses 
brighter than f/5.6.
* Except with the EF28-80mm f/2.8-4L USM and EF50mm f/2.5 Compact Macro lenses.

Autofocus can fail to achieve focus (the focus confirmation light 
blinks) with certain subjects such as the following:
Subjects difficult to focus
  Low-contrast subjects
Example: Blue sky, solid-color walls, etc.
  Subjects in low light
  Extremely backlit and reflective subjects
Example: Car with a reflective body, etc.
  Overlapping near and far objects
Example: Animal in a cage, etc.
  Repetitive patterns
Example: Skyscraper windows, computer keyboards, etc.
In such cases, do one of the following:
(1) Focus an object at the same distance as the subject and lock the  focus before recomposing. (p.48)
(2) Set the lens focus mode switch to < MF> and focus manually.
1Set the lens focus mode switch to 
.
2Focus the subject.
 Focus by turning the lens focusing 
ring until the subject looks sharp in 
the viewfinder.
