 About the Histogram
The brightness histogram display shows the exposure level 
distribution, overall brightness, and gradation. And the RGB 
histogram display is for checking the color saturation and gradation. 
The display can be switched with the [3 Histogram] menu.
[Brightness] Display
This histogram is a graph showing the 
distribution of the image’s brightness level. The 
horizontal axis indicates the brightness level 
(darker on the left and brighter on the right), 
while the vertical axis indicates how many 
pixels exist for each brightness level. The more 
pixels there are toward the left, the darker the 
image. And the more pixels there are toward the 
right, the brighter the image. If there are too 
many pixels on the left, the shadow detail will be 
lost. And if there are too many pixels on the 
right, the highlight detail will be lost. The 
gradation in-between will be reproduced. By checking the image and 
its brightness histogram, you can see the exposure level inclination 
and the overall tone reproduction condition.
[RGB] Display
This histogram is a graph showing the distribution of the image’s 
brightness level of each primary color (RGB or red, blue, and green). 
The horizontal axis indicates the color’s brightness level (darker on the 
left and brighter on the right), while the vertical axis indicates how 
many pixels exist for each color brightness level. The more pixels 
there are toward the left, the darker and less prominent the color. And 
the more pixels there are toward the right, the brighter and denser the 
color. If there are too many pixels on the left, the respective color 
information will be lacking. And if there are too many pixels on the 
right, the color will be too saturated with no detail. By checking the 
image’s RGB histogram, you can see the color’s saturation and 
gradation condition and white balance inclination.

Printing Images and
Transferring Images to a Computer
 Printing (p.134)
You can connect the camera directly to a printer and print 
out the images in the card. The camera is compatible with 
“wPictBridge” which is the standard for direct printing. 
The Web site below gives more information on using your 
Canon camera with various printers, such as which paper 
types to use.
http://canon.com/pictbridge/
 Digital Print Order Format (DPOF) (p.143)
DPOF (Digital Print Order Format) enables you to print 
images recorded in the card according to your printing 
instructions such as the image selection, quantity to print, 
etc. You can print multiple images in one batch or give the 
print order to a photofinisher.
 Transferring Images to a Personal Computer (p.147)
By connecting the camera to a personal computer, you can 
transfer images from the camera’s card by operating the 
camera.
