D Using the Built-in Flash
 If the subject is far away, increase the ISO speed  (p.79).
By increasing the ISO speed,  you can extend the flash range.
  In bright light, decrease the ISO speed.
If the exposure setting in the view finder blinks, decrease the ISO 
speed.
  Detach the lens hood and keep at least 1 meter/3.3 feet away 
from the subject.
If the lens has a hood attached or  you are too close to the subject, 
the bottom of the picture might look dark due to the obstructed flash. 
For important shots, check the im age on the LCD monitor to make 
sure the flash exposure looks natural (not dark at the bottom).
Using the red-eye reduction lamp  before taking a flash picture can 
reduce red eye. Red-eye reduction  will work in any shooting mode 
except , < 3>, < 5>, or < k>.
  Under the [ 1] tab, select [Red-eye 
reduc. ], then press < 0>. Select 
[Enable ], then press < 0>.
 
For flash photography, when you press 
the shutter button halfway, the red-eye 
reduction lamp will light. Then when 
you press the shutter button 
completely, the picture will be taken.
Shooting Tips
3  Red-eye Reduction
 The red-eye reduction feature is most  effective when the subject looks at 
the red-eye reduction lamp, when the  room is well lit, or when you are 
close to the subject.
  When you press the shut ter button halfway, the 
scale display on the botto m of the viewfinder will 
shrink and turn off. For bes t results, take the picture 
after this scale display turns off.
  The effectiveness of red-eye reductio n varies depending on the subject.

Advanced Shooting
This chapter builds on Chapter 3 and introduces more 
ways to shoot creatively.
  The first half of this chapte r explains how to use the < s>, 
< f >, , and < 8> modes on the Mode Dial.
  All the functions explained in C hapter 3 can also be used in 
the < s>, < f >, and < a> modes.
  To see which functions can be  used in each shooting mode, 
see page 268.
  The  M mark shown on the right of the page title indicates 
that the function is available only in Creative Zone modes 
(p.22).
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.

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.

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 1/30 sec. or slower. Use a tripod to 
prevent hand-held camera shake.
  Set the shutter speed so that the aperture display does not 
blink.
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 blur the background or to make everything near and far look sharp, 
set the Mode Dial to  (Aperture-priority AE) to adjust the depth of 
field (range of acceptable focus).

2Set the desired aperture.
 The higher the f/number, the wider 
the depth of field where sharper focus 
is obtained in both the foreground 
and background.
  Turning the < 6> dial to the right will 
set a higher f/number (smaller 
aperture opening), and turning it to 
the left will set a lower f/number 
(larger aperture opening).
3Take the picture.
  Focus and press the shutter button 
completely. The picture will be taken 
with the selected aperture.

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.

f: Changing the Depth of Field
 When using an aperture with a  high f/number, note that camera 
shake can occur in low light scenes.
A higher aperture f/number will ma ke the shutter speed slower. 
Under low light, the shutter speed ca n be as long as 30 sec. In such 
cases, increase the ISO speed and hol d the camera steady or use a 
tripod.
  The depth of field depends not onl y on the aperture, but also on 
the lens and on the subject distance.
Since wide-angle lenses have a wide depth of field (range of 
acceptable focus in front of and beh ind the point of focus), you need 
not set a high aperture f/number to  obtain a sharp picture from the 
foreground to the background. On the other hand, a telephoto lens 
has a narrow depth of field.
And the closer the subject, the narro wer the depth of field. A farther 
subject will have a wider depth of field.
  Set the aperture so that the  shutter speed display does not 
blink.
If you press the shutter  button halfway and change 
the aperture while the shutter speed is displayed, 
the shutter speed display will also change to 
maintain the same exposure (amount of light 
reaching the image sensor). If you exceed the 
adjustable shutter speed  range, the shutter speed 
display will blink to indicate that the standard 
exposure cannot be obtained.
If the picture will be too dark, the “ 30” (30 sec.) shutter speed 
display will blink. If th is happens, turn the < 6> dial to the left to set 
a lower aperture f/number or increase the ISO speed.
If the picture will be too bright, the “ 4000” (1/4000 sec.) shutter 
speed display will blink.  If this happens, turn the < 6> dial to the 
right to set a higher aperture f/number or decrease the ISO speed.

To obtain a correct flash expos ure, the flash output will be set 
automatically to match the set a perture (autoflash exposure). The 
shutter speed will be set automatically  between 1/200 sec. - 30 sec. to 
suit the scene’s brightness.
In low light, the main subject is ex posed with the automatic flash, and 
the background is exposed with a slow  shutter speed set automatically. 
Both the subject and background look properly exposed (automatic 
slow-speed flash sync). If you ar e handholding the camera, keep it 
steady to prevent camera shake. Using a tripod is recommended.
If you do not want a slow s hutter speed to be used, set [ 3: Flash sync. 
speed in Av mode] to [ 1: 1/200-1/60 sec. auto ] or [2: 1/200 sec. 
(fixed) ] in [7  Custom Functions (C.Fn) ] (p.252).
The aperture opening (diaphragm) changes only at the moment when 
the picture is taken. Otherwise,  the aperture remains fully open. 
Therefore, when you look at the  scene through the viewfinder or LCD 
monitor, the depth of field will look narrow.
When you press the depth-of-field 
preview button, you can see the actual 
depth of field before you shoot.

To obtain a correct flash expos ure, the flash output will be set 
automatically (autoflash exposure)  to match the manually-set aperture. 
The flash sync speed can be set fr om 1/200 sec. to 30 sec. and bulb.
A bulb exposure keeps the shutter open 
for as long as you hold down the shutter 
button. It can be used to photograph 
fireworks, etc.
In step 2 on the preceding page, turn the 
< 6 > dial to the left to set < BULB>. 
The elapsed exposure time will be 
displayed on the LCD monitor.
I  Using the Built-in Flash
BULB: Bulb Exposures
  During the bulb exposure, do not po int the lens toward the sun. The 
sun’s heat can dam age the camera’s in ternal components.
  Since bulb exposures produce more noise than usual, the image might 
look a little grainy.
  You can reduce the noise due to  long exposures by setting [4: Long exp. 
noise reduction ] to [1: Auto ] or [2: On ] in the [7  Custom Functions 
(C.Fn) ] (p.253).
 For bulb exposures, using a tripod  and Remote Switch (sold separately, 
p.262) is recommended.
  You can also use a remote  controller (sold separately, p.261) for bulb 
exposures. When you press  the remote controller’s transmit button, the 
bulb exposure will star t immediately or 2 sec.  later. Press the button 
again to stop the bulb exposure.
