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.

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...

94
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...

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.

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).
*  stands for Aperture value wh ich is the size of the diaphragm hole inside the lens.
1Set the Mode Dial to .
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...

97
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...

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)....

You can set both the shutter speed and aperture manually as desired. 
While referring to the exposure level indicator in the viewfinder, you can 
set the exposure as desired. This method is called manual exposure.
* < a> stands for Manual.
