s: Conveying the Subject’s Movement
To freeze the motion of a fast-moving subject
Use a fast shutter speed such as 1/4000 sec. to 1/500 sec.
 To blur a running child or animal and convey an impression of 
motion
Use a medium shutter speed such as 1/250 sec. to 1/30 sec. Follow 
the moving subject through the viewfinder and press the shutter 
button to take the picture. If you use a telephoto lens, hold it steady 
to prevent camera shake.
 To blur a flowing river or fountain
Use a slow shutter...

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).
*< f > stands for Aperture value, which is the size of the diaphragm hole inside the lens.
1Set the Mode Dial to < f>.
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: Changing the Depth of Field
When using an aperture with a high f/number or shooting in low 
light scenes, note that camera shake can occur.
A higher aperture f/number will make the shutter speed slower. 
Under low light, the shutter speed can be as long as 30 sec. In such 
cases, increase the ISO speed and hold the camera steady or use a 
tripod.
 The depth of field depends not only on the aperture, but also on 
the lens and on the subject distance.
Since wide-angle lenses have a wide depth of...

To obtain a correct flash exposure, the flash output will be set 
automatically to match the set aperture (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  exposed with the auto flash metering, 
and the background is exposed with a slow shutter speed set 
automatically. Both the subject and  background look properly exposed  
with a touch of atmosphere...

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.
* stands for Manual.
1Set the Mode Dial to < a>.
2Set the ISO speed (p.122).
3Set the shutter speed and aperture.
 To set the shutter speed, turn the 
 dial.

a: Manual Exposure
156
To obtain a correct flash exposure, the flash output will be set 
automatically (autoflash exposure)  to match the manually-set aperture. 
The shutter speed can be set from 1/200 sec. to 30 sec or bulb.
A bulb exposure keeps the shutter open 
for as long as you hold down the shutter 
button. It can be used to shoot fireworks 
and other subjects requiring long 
exposures.
In step 3 on the preceding page, turn the 
 dial to the left to set < BULB>. 
The elapsed exposur e time will be...

Four methods (metering modes) to measure the subject’s brightness 
are provided. Normally, evaluative metering is recommended.
In Basic Zone modes, metering mode is set automatically.
1Select [Metering mode].
 Under the [z 2] tab, select [Metering 
mode ], then press < 0>.
2Set the metering mode.
 Select the desired metering mode, 
then press < 0>.
q  Evaluative metering 
General-purpose metering mode suited even 
for backlit subjects. The camera sets the 
exposure automatically to suit the scene....

e Center-weighted average metering
The brightness is metered at the image center 
and then averaged for the entire scene. This 
metering mode is for advanced users.
With  q (Evaluative metering), the exposure setting will be locked when you 
press the shutter button halfway and focus is achieved. In the  w (Partial 
metering),  r (Spot metering), and  e (Center-weighted average metering) 
modes, the exposure is set at the moment  the picture is taken. (Pressing the...

Set exposure compensation if the exposure (without flash) does not 
come out as desired. This feature can be used in Creative Zone modes 
(except < a>). You can set the exposure compensation up to ±5 stops 
in 1/3-stop increments.
1Check the exposure level indicator.
 Press the shutter button halfway 
(0 ) and check the exposure level 
indicator in the viewfinder or on the 
LCD monitor.
2Set the compensation amount.
If the exposure is too dark, hold down 
the  button and turn the  
dial to the...

This feature takes exposure compensation a step further by varying the 
exposure automatically (up to ±2 stops in 1/3-stop increments) with 
three shots as shown below. You can then choose the best exposure. 
This is called AEB (Auto Exposure Bracketing).
1Select [Expo.comp./AEB].
 Under the [ z2] tab, select 
[ Expo.comp./AEB ], then press .
2Set the AEB range.
 Turn the < 6> dial to set the AEB 
range.
 Press the < Y> < Z> keys to set the 
exposure compensation amount. If 
AEB is combined with...
