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 field (range of 
acceptable focus in front of and behind 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 narrower 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 this happens, turn the  dial to the left to set 
a lower 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 f/number or decrease the ISO speed.

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 (autom atic slow-speed flash sync). If you 
are handholding the camera, keep it steady to prevent camera shake. 
Using a tripod is recommended.
To prevent a slow shutter speed, under [ 53: Custom Functions 
(C.Fn) ], set [3: Flash sync. speed in Av mode ] to [1: 1/200-1/60sec. 
auto ] or [2: 1/200sec. (fixed)] (p.261).
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 on the 
LCD monitor, the depth of field will look narrow. With the procedure 
below, you can check the depth of field before taking the picture.
1Enable depth-of-field  preview to be used.
Under [5 3: Custom Functions (C.Fn) ], set [9: Assign SET 
button ] to [4: Depth-of-field preview ] (p.266).
 For details about Custom Function settings, see page 258.
2Exit the menu.
Press the < M> button two times to exit the menu.
3Press the < 0> button.
The aperture will be stopped down so you can see the depth of field.

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.

speed and aperture in order to obtain the standard exposure. Therefore, 
you may not obtain the desired exposure effect. 
						

							a: Manual Exposure

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 to 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 
displayed on the LCD monitor.
I  Using the Built-in Flash
BULB: Bulb Exposures
Elapsed exposure time
 Do not point the camera toward an intense light source, such as the sun 
or an intense artificial light source. Doing so may damage the image 
sensor or the camera’s internal components.
 Since bulb exposures produce more noise than usual, the image may 
look slightly grainy.
 You can reduce the noise due to long exposures by setting [ 4: Long exp. 
noise reduction ] under [53: Custom Functions (C.Fn) ] to [1: Auto ] or 
[ 2: On ] (p.262).
 If ISO Auto is set for a bulb exposure, the ISO speed will be fixed at ISO 
800 (p.94).
For bulb exposures, using a tripod and  a remote switch (sold separately, 
p.271) is recommended.

Three 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.
w  Partial metering
Effective where there are much brighter lights 
around the subject due to backlight, etc. The 
gray area in the left figure is where the 
brightness is metered to obtain the standard 
exposure.
e Center-weighted  average meteringThe brightness is metered at the image center 
and then averaged for the entire scene. This 
metering mode is for advanced users.
q Changing the Metering ModeN
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) and  e (Center-weighted average metering) modes, the 
exposure is set at the moment the pi cture is taken. (Pressing the shutter 
button halfway does not lock the exposure.)

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.
Making it brighter
Hold down the < O> button and 
turn the < 6> dial to the right 
(increased exposure).
Making it darker
Hold down the < O> button and 
turn the < 6> dial to the left 
(decreased exposure).
 As shown in the figure, the exposure 
level is displayed on the LCD monitor 
and in the viewfinder.
 After taking the picture, cancel the 
exposure compensation by setting 
it back to 0.

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 [z 2] 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 exposure 
compensation, AEB will be applied 
centering on level of exposure 
compensation.
