White balance (WB) is for making the white areas look white. Normally, 
the  (Auto) setting will obtain the correct white balance. If natural-
looking colors cannot be obtained with <
Q>, you can select the white 
balance for each light source or set it manually by shooting a white 
object. In the Basi c Zone modes,  will be set automatically.
1Press the  button. (9 )
2Select the white balance.
 While looking at the LCD panel, turn 
the < 5> dial.
To the human eye, a white object looks white regardless of the type of 
lighting. With a digital camera, the color temperature is adjusted with 
software to make the white areas look white. This adjustment serves as 
the basis for the color correction. The result is natural-looking colors in 
the pictures.

You can set the white balance’s color temperature numerically in Kelvin. This is for advanced users.
1Select [White balance].
 Under the [2 ] tab, select [White 
balance ], then press < 0>.
2Set the color temperature.
  Turn the < 5> dial to select [ P].
  Turn the < 6> dial to set the color 
temperature, then press < 0>.
  The color temperature can be set 
from 2500K to 10000K in 100K 
increments.
P Setting the Colo r Temperature
 If the exposure obtained in step 1 is way off, a correct white balance 
might not be obtained.
  If the image was captured while the Picture Style was set to 
[Monochrome ] (p.66), it cannot be selected in step 3.
 Instead of a white object, an 18% gray card (commercially available) can 
produce a more accurate white balance.
  The personal white balance registered with the provided software will be 
registered under < O>. If you do step 3, the data for the registered 
personal white balance will be erased.
  When setting the color temperature for an artificial light source, set white 
balance correction (magenta or green) as necessary.
  If you want to set < P> to the reading taken with a commercially-
available color temperature meter, take test shots and adjust the setting 
to compensate for the difference between the color temperature meter’s 
reading and the camera’s color temperature reading.

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>.
2Set the white balance correction.
  Use < 9> 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.

White Balance Correction
Sample setting: A2, G1
 During the white balance correction, < u> will be displayed in the 
viewfinder and on the LCD panel.
  One level of the blue/amber correction is equivalent to 5 mireds of a color 
temperature conversion filter. (Mired: Measuring unit indicating the 
density of a color temperature conversion filter.)

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.
X On the right side of the screen, “ BKT” 
indicates the bracketing direction and 
the bracketing amount.
 
Pressing the  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, 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 card will take longer to 
record the shot.
  “BKT ” stands for Bracketing.

Due to the lens characteristics, the four corners of the picture might look 
darker. This is called lens light fall-o ff or drops in peripheral illumination. 
This can be corrected. For JPEG imag es, lens light fall-off is corrected 
when the image is captured. For RAW images, it can be corrected with 
Digital Photo Professional (provided software).
1Select [Peripheral illumin. 
correct.].
  Under the [1 ] tab, select 
[Peripheral illumin. correct.], then 
press < 0>.
2Check the screen.
  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.
  Turn the < 5> dial to select [ Enable], 
then press < 0>.
3Take the picture.
  The image will be displayed with the 
corrected peripheral light.

3 Lens Peripheral Illumination Correction
The camera already contains lens  peripheral light correction data for 
about 20 lenses. In step 2, if you select [ Enable], the peripheral light 
correction will be applied automatical ly for any lens whose correction 
data has been registered in the camera.
With the EOS Utility (provided soft ware), you can check which lenses 
have their correction data registered in the camera. You can also 
register the correction data for unregi stered lenses. For details, see the 
Software Instruction Manual (CD-ROM) for EOS Utility.
About the Lens Correction Data
  For JPEG images already captured, lens peripheral light correction 
cannot be applied.
  Depending on shooting conditions, noise might appear on the image 
periphery.
  When using a third-party lens setting the correction to [ Disable] is 
recommended, even if [ Correction data available ] is displayed.
 Lens peripheral light correction 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 Digital Photo Professional (provided 
software).
  If the lens does not have distance information, the correction amount will 
be lower.
  The higher the ISO speed, the lower the correction amount will be.
  The correction might not be noticeable with lenses whose peripheral light 
fall-off is minimal.

About FoldersAs with “ 100CANON ” for example, the folder name starts with three digits 
(folder number) followed by five alphanum eric characters. A folder can contain 
up to 9999 images (file No. 0001 - 9999). When a folder becomes full, a new 
folder with a higher one-up folder number is created automatically. Also, if 
manual reset (p.81) is executed, a new folder will be created automatically. 
Folders numbered from 100 to 999 can be created.
Creating Folders with a Personal ComputerWith the card open on the screen, create a new folder named “ DCIM”. Open 
the DCIM folder and create as many folders as necessary to save and 
organize your images. The folder name must follow the “ 100ABC_D” format 
where the first three digits is 100  - 999 followed by five alphanumeric 
characters. The five characters can be  a combination of upper- or lower-case 
letters from A to Z, numerals, and an underscore “_”. There can be no space in 
the folder name. Also, folder names cannot have the same three-digit number 
such as “100ABC_D” and “100W_XYZ” even if the letters are different.

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 change how the file number is assigned.
The file number will appear on a 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>.
Continues the file numbering sequence even after the card is 
replaced or a new folder is created.
Even after you replace the card or create a new folder, 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 multiple cards or folders into one folder in your personal 
computer.
If the replacement card or existing folder already contains images 
recorded previously, the file numbering of the new images might 
continue from the file numbering of the existing images in the card or 
folder. If you want to use continuous file numbering, you should use a 
newly-formatted card each time.
