Advanced Shooting
This chapter buitds on the previous chapter and
introduces more ways to shoot creatively.
_ The first half of this chapter explains how to use the <Tv>
<Av > < M > <A-DEP> modes on the Mode Dial. Except for
<A-D[P>, all the shooting modes can be used in
combination with the functions introduced in Chapter 3.
_ The second half of this chapter, starting with "Changing the
Metering Mode" explains the methods to adjust the
exposure and the Picture Styles. All the functions
introduced in this chapter can also be used with the <P>
(Program AE) mode introduced in Chapter 3.
_ About the Main Diat Pointer
The pointer icon <_> displayed
together with the shutter speed, aperture
setting, or exposure compensation
amount indicates that you can turn the
<_ > dial to adjust the respective
setting.

Tv' Action Shots
You can either freeze the action or create motion blur with the <Tv>
(Shutter-priority AE) mode on the Mode Dial.
*<Tv> standsfor Time value.
Frozen action Blurred motion
(Slow shutter speed: 1/30 sec.)(Fast shutter speed: 1/2000 sec.)
Set the Mode Dial to <Tv>.
_j, Set the desired shutter speed.
i ® See "Shooting Tips" for advice on
setting the shutter speed.
® Turning the <_> dial to the right
sets a faster shutter speed, and
turning it to the left sets a slower one.
Take the picture.
® When you focus and press the
shutter button completely, the picture
will be taken at the selected shutter
speed.
The LCB monitor displays the shutteE speed as a fraction. However, the
viewfinder displays only the denom!natoE. Also, 'Q,!51!indicates 0.5 sec, and
,15"" is 15 sec.

Tv: Action Shots
#_.'- Shooting Tips
®_To freeze the action or moving subject.
Use a fast shutter speed such as 114000 sec. to 11500 sec.
_To blur a running child or animaJ giving the impression of fast
movement.
Use a medium shutter speed such as 1/250 sec. to 1130 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.
®_How to bJur aflowing 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 dispJay does not
blink inthe vJewfindero
If you press the shutter button haFway 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 <_> 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 <_ > dial to the right to
set a faster shutter speed or decrease the ISO speed.
Using the Built_in Flash
To obtain a correct flash exposure, the flash output will be set
automatically (autoflash exposure) to match the automatically-set
aperture. The flash sync speed can be set from 11200 sec. to 30 sec.

Av' Changing the Depth of Field
To obtain a blurry background or to make everything near and far look
sharp, set the Mode Dial to <Av> (Aperture-priority AE) to adjust the
depth of field (range of acceptable focus),
*<Av > standsfor Aperture value which isthe size ofthe diaphragm hole inside
the lens.

Av : Changing the Depth of Field
Cd-'-shootingTips
_ When using an aperture with a high f-number, note that camera
shake can occur in Jow light scenes.
A higher aperture #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
tdpod.
_ The depth of fieJd depends not on?y on the aperture, but also
the lens and subject distance.
Since wide-angle lenses have a wide depth of field (range of
acceptable focus infront of and behind the point of focus), you need
not set a high aperture #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 in the viewfindero
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. Ifthis happens, turn the <_ > dial to the lef_to set
a lower aperture f-number or increase the ISO speed.
If the picture will be too bdght, the "4000" (1/4000 sec.) shutter
speed display will blink. If this happens, turn the <_> dial to the
dght to set a higher aperture #number or decrease the ISO speed.

Av : Changing the Depth of Field
Using the Built,in Flash
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 11200 sec. - 30 sec. to
suit the scene's brightness.
In low light, the main subject is exposed 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 are handholding the camera, keep it
steady to prevent camera shake. Using a tripod is recommended.
If you do not want a slow shutter speed to be used, set the [_ Custom
Functions (CoFn)] menu's [Flash synco speed in Av mode] to [1: 1t
200-1160 sec. auto] or [2:1/200 sec. (fixed)] (p.192).
Depth of Field Preview_
Press the depth=of=field preview button
to stop down to the lens's current
aperture setting. You can then check the
depth of field (range of acceptable focus)
through the viewfinder.
The depth_0f-field effect Can be Clearly seen on the Live View image as you
change the aperture and press the depth-of-fie!d preview button (p,112),

M' Manual Exposure
You can set both the shutter speed and aperture manually as desired.
With flash, the flash exposure will be set automatically to match the
aperture that was set. The flash sync speed can be set within 1/200
sec. to 1/30 sec. or to bulb.

M: Manual Exposure
Bulb Exposures
In step 2 on the preceding page, turn the
<_> dial to the left to set <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. The elapsed exposure
time will be displayed on the LCD
monitor.
,® Since bulb exposures produce more noise than usual, the image might
look a little gra ny
You can reduce this noise by setting the [9=- Custom Functions (C.Fn)]
menu's [Long exp. noise reduction] to [1: Autoj or [2: On] (p=193).

For bulb exposures, using a tripod and Remote Switch (p.204,205) is
recommended.
_}.You can also use a remo_e controller (sold separately, p.204) for I:UIO
exposures. When you press the remo-[e comforter's transmit button, the
DUIDexposure will start _mmedlate_y or 2 sec. later. Press the button
again to stop the bulb exposure.

A-DEP:Automatic Depth-of°Field AE

_ Aim the AF points over the subjects
and press the shutter button halfway
(¢4).
e_All the subjects covered by the AF
points flashing in red will be in focus.
Take the picture.
_ The aperture display in the viewfinder blinks.
The exposure is correct, but the desired depth of field cannot be
obtained. Either use a wide-angle lens or move farther away from
the subjects.
®_The shutter speed display in the viewfinder blinks.
If the "30'"' shutter speed blinks, it means that the subject is too dark.
Increase the ISO speed. If the "4000" shutter speed blinks, it means
that the subject is too bright. Decrease the ISO speed.
_ A slow shutter speed has been set.
Use a tripod to steady the camera.
®_I want to use flash.
Flash can be used, however, the result will be the same as using the
<P> mode with flash. The desired depth of field will not be obtained.
