3 Setting the Image-recording Quality
 I want to select the image-reco rding quality matching the paper 
size for printing. Refer to the diagram on the left when 
choosing the image-recording quality. If 
you want to crop the image, selecting a 
higher quality (more pixels) such as 73 , 
83 , 1 , or 1 +73  is recommended.
  What ’s the difference between 
7 and 8?
It indicates a different image quality due to a different compression 
rate. Even with the same number of pixels, the 
7 image has higher 
image quality. If 
8 is selected, the image quality will be slightly lower, 
but more images can be saved to the card.
  I took more shots th an the number of possible shots indicated.
Depending on the shooting conditions, you may be able to take 
more shots than was indicated. Or, it might be fewer than indicated. 
The number of possible shots displayed is only an estimate.
  Does the camera display the maximum burst?
The maximum burst is displayed in  the viewfinder’s right side. Since 
it is only a single-digit indicator  0 - 9, any number higher than 9 will 
be displayed only as “ 9.” Note that this number will also be displayed 
even when no card is installed in th e camera. Be careful not to shoot 
without a card in the camera.
  When should I use 
1?
1 images require processing with  your computer. For details, see 
“About 1” and “About 1+73” on the next page.
Other than 1, the images will be in  the JPEG type commonly used 
in digital cameras.

Although 1 images require software lik e Digital Photo Professional 
(provided) so they can be displayed on  the computer, they also offer flexibility 
for image adjustments possible only with 
1. 1 is effective when you 
want to precisely adjust the image your self or shoot an important subject.
1+73 records both a 1 and 73 image with a single shot. The two 
images are saved to the card simultaneously. The two images will be saved 
in the same folder with the same file numbers (file extension .JPG for JPEG 
and .CR2 for RAW). 
73 images can be viewed or printed even with a 
computer which does  not have the camera

Advanced Shooting
This chapter builds on the previous chapter and 
introduces more ways  to shoot creatively.
 The first half of this chapter explains how to use the < s> 
< f >   modes on the Mode Dial. Except for 
< 8 >, all the shooting modes can be used in 
combination with the functions introduced in Chapter 3.
  The second half of this chapt er, starting with “Changing the 
Metering Mode” explains the methods to adjust the 
exposure and the Picture Styles. All the functions 
introduced in this chapter c an also be used with the  
(Program AE) mode introduced in Chapter 3.
The pointer icon  displayed 
together with the shutter speed, aperture 
setting, or exposure compensation 
amount indicates that you can turn the 
< 6 > dial to adjust the respective 
setting.

You can either freeze the action or create motion blur with the  
(Shutter-priority AE) mode on the Mode Dial.
* < s> stands for Time value.
1Set the Mode Dial to < s>.
2Set the desired shutter speed.
 See “Shooting Tips” for advice on 
setting the shutter speed.
  Turning the < 6> dial to the right 
sets a faster shutter speed, and 
turning it to the left sets a slower one.
3Take the picture.
  When you focus and press the 
shutter button completely, the picture 
will be taken at the selected shutter 
speed.
s: Action Shots
Frozen action
(Fast shutter speed: 1/2000 sec.) Blurred motion
(Slow shutter speed: 1/30 sec.)
Shutter Speed Display
The LCD monitor displays  the shutter speed as a fraction. However, the 
viewfinder displays only the denominator. Also, “ 05” indicates 0.5 sec. and 
“ 15 ” is 15 sec.
COPY  
						

							79
s: Action Shots
 To freeze the action or moving subject.
Use a fast shutter speed such  as 1/4000 sec. to 1/500 sec.
  To blur a running child or animal giving the impression of fast 
movement.
Use a medium shutter speed such as  1/250 sec. to 1/30 sec. Follow 
the moving subject through the vi ewfinder and press the shutter 
button to take the picture. If you use a telephoto lens, hold it steady 
to prevent camera shake.
  How to blur a flowing river or water fountain.
Use a slow shutter speed of 1/15 sec. or slower. Use a tripod to 
prevent camera shake.
  Set the shutter speed so that the aperture display does not 
blink in the viewfinder.
If you press the shutter button halfway and change 
the shutter speed while the aperture is displayed, 
the aperture display will also change to maintain the 
same exposure (amount of light reaching the image 
sensor). If you exceed the adjustable aperture 
range, the aperture display will blink to indicate that 
the standard exposure cannot be obtained.
If the exposure will be too dark, the maximum aperture (smallest 
number) will blink. If this happens, turn the < 6> dial to the left to 
set a slower shutter speed  or increase the ISO speed.
If the exposure will be too bright,  the minimum aperture (highest 
number) will blink. If this happens, turn the < 6> dial to the right to 
set a faster shutter speed or decrease the ISO speed.
To obtain a correct flash expos ure, the flash output will be set 
automatically (autoflash exposure)  to match the automatically-set 
aperture. The flash sync speed can be set from 1/200 sec. to 30 sec.

To obtain a blurry background or to make everything near and far look 
sharp, set the Mode Dial to < f> (Aperture-priority AE) to adjust the 
depth of field (range of acceptable focus).
* < f> stands for Aperture valu e which is the size of the diaphragm hole inside 
the lens.
1Set the Mode Dial to < f>.
2Set the desired aperture.
 The higher the aperture f-number, the 
sharper the picture will look with a 
wider depth of field.
  Turning the < 6> dial to the right will 
set a higher f-number, and turning it 
to the left will set a lower f-number.
3Take the picture.
  Focus and press the shutter button 
completely. The picture will be taken 
with the selected aperture.
f: Changing the Depth of Field
Blurred background(With a low aperture f-number: f/5.6)Sharp foreground and background(With a high aperture f-number: f/32)
Aperture Display
The higher the f-number, the smaller  the aperture opening will be. The 
apertures displayed will differ  depending on the lens. If no lens is attached to 
the camera, “ 00” will be displayed for the aperture.
