BASIC IMAGE RECORDING

This section describes the basic procedure for recording an

image.

Recording an Image

Aiming the Camera

Use both hands to hold the camera still when shooting an

image. Holding the camera with one hand increases the

chance of movement, which can blur your images.

•Horizontal Hold the camera

still in both

hands, with your

arms firmly

against your

sides.

•Vertical When holding

the camera

vertically, make

sure that the

flash is above

the lens. Hold

the camera still

with both hands.

IMPORTANT!

•Make sure your fingers or the strap does not block

the flash or lens.

NOTE

•Your image will be blurred if you move the camera

when pressing the shutter release button. Press the

shutter release button carefully, taking care that

there is no camera movement. This is especially

important when available lighting is low, which slows

down the shutter speed.

BASIC IMAGE RECORDING

Compose the image

on the monitor

screen.

•You can compose

images using either the

monitor screen or the

optical viewfinder.

•When using the optical viewfinder, you can turn off

the monitor screen to save power (page 25).

Press the shutter

release button to

record the image.

•The number of images that can be stored in memory

depends on the resolution setting you are using

(pages 52, 183).

•Depending on the distance or angle between the

subject and the camera, the image you see in the

viewfinder may not be exactly the image that is

recorded.

Recording an lmage

Your camera automatically adjusts shutter speed in

accordance with the brightness of the subject. Images you

record are stored in the camera’s built-in memory, or to a

memory card if you have one loaded in the camera.

•When an optionally available SD memory card or

MultiMediaCard (MMC) is loaded in the camera, images

are stored on the card (page 125).

Press the power button

to turn on the camera.

•This causes an image or

a message to appear on

the monitor screen.

Align the mode

selector with “ ”

(REC).

•This enters the REC

mode for image

recording.

BASIC IMAGE RECORDING

About the REC Mode Monitor Screen

•The image shown on the monitor screen in the REC

mode is a simplified image for composing purposes. The

actual image is recorded in accordance with the image

quality setting currently selected on your camera. The

image saved in file memory has much better resolution

and detail than the REC mode monitor screen image.

•Certain levels of subject brightness can cause the

response of the REC mode monitor screen to slow down,

which causes some static noise in the monitor screen

image.

Recording Precautions

•Never open the battery cover or place the camera onto

the USB cradle while the operation/flash charge lamp is

flashing. Doing so not only causes the current image to

be lost, it can also corrupt images already stored in file

memory and even lead to malfunction of the camera.

•Never remove the memory card while an image is being

recorded to the memory card.

•Fluorescent lighting actually flickers at a frequency that

cannot be detected by the human eye. When using the

camera indoors under such lighting, you may experience

some brightness or color problems with recorded images.

•When “Auto”is selected for the ISO sensitivity setting

(page 72), the camera automatically adjusts its sensitivity

in accordance with the brightness of the subject. This can

cause some static noise to appear in images of relatively

dark subjects.

•When “Auto”is selected for the ISO sensitivity setting

(page 72), the camera raises the sensitivity and uses a

faster shutter speed. Because of this, you need to guard

against camera movement if you have flash turned off

(page 47) when recording a dimly lit subject.

•If unwanted light is shining on the lens, shade the lens

with your hand when recording the image.

BASIC IMAGE RECORDING

Using Zoom

You can use the digital zoom feature of your camera to

zoom in on the center of an image. Performing a zoom

operation toggles the zoom factor between 1X and 4X.

In the REC mode, press [MENU].

Use [] and [] to select the “REC”tab.

Use [] and [] to select “Digital Zoom”, and

then press [].

Use [] and [] to select “On”, and then

press [SET].

•Selecting “Off”disables digital zoom.

Record the image.

Zoom out Zoom in

In the REC mode, use [] and [] to change

the digital zoom factor.

[] : Zoom in.

[] : Zoom out.

BASIC IMAGE RECORDING

IMPORTANT!

•Zoom is disabled whenever the monitor screen is

turned off (page 25).

•Using digital zoom can cause degradation of the

recorded image.

•To disable digital zoom, select “Off”for the “Digital

Zoom”setting on the “REC”tab.

NOTE

•You can use the key customization feature (page 75)

to configure the camera so the digital zoom factor

changes whenever you press [] and [] while in the

REC mode.

Using the Flash

Perform the following steps to select the flash mode you

want to use.

In the REC mode, press [MENU].

Use [] and [] to select the “REC”tab.

Use [] and [] to select “Flash”, and then

press [].

Use [] and [] to select the flash mode you

want, and then press [SET].

To do this:

Have the flash fire automatically

when required (Auto Flash)

Turn off the flash (Flash Off)

Always fire the flash (Flash On)

Fire a pre-flash followed by image

recording with flash, reducing the

chance of red-eye in the image (Red-

eye reduction). Have the flash fire

automatically when required.

Select this setting:

Auto

BASIC IMAGE RECORDING

Record the image.

IMPORTANT!

•The flash unit of this camera fires a number of times

when you record an image. The initial flashes are

pre-flashes, which the camera uses to obtain

information it uses for exposure settings. The final

flash is for recording. Make sure that you keep the

camera still until the shutter releases.

•Image recording may not be performed if you press

the shutter release button while the operation/flash

charge lamp is flashing amber.

NOTE

•You can use the key customization feature (pages

74, 75) to configure the camera so the flash mode

changes whenever you press [] and [], or [] and

[] while in the REC mode.

■About Red-eye Reduction

Using the flash to record at night or in a dimly lit room can

cause red spots inside the eyes of people who are in the

image. This is caused when the light from the flash reflects

off of the retina of the eye. Red-eye reduction fires a pre-

flash, which causes the irises in the eyes of any people in

the image to close. This is followed by another flash

operation when the image is actually recorded.

IMPORTANT!

Note the following important points when using red-

eye reduction.

•Red-eye reduction does not work unless the people

in the image are looking directly at the camera

(flash). Before pressing the shutter release button,

call out to the subjects so they all look at the camera.

•Red-eye reduction may not work very well if the

subjects are located far away from the camera.

BASIC IMAGE RECORDING

Flash Precautions

Take care that your fingers do not block the flash when you

hold the camera. Covering the flash with your finger can

greatly reduce its effectiveness.

•The approximate effective range of the flash is shown

below. The flash is unable to adequately illuminate a

subject that is outside this range.

0.8 meter to 1.5 meters (2.6´to 4.9´) (ISO Sensitivity :

“Auto”)

•The flash takes anywhere from a few seconds as long as

10 seconds to attain full charge after being fired. The

actual time required depends on the battery level,

temperature, and other conditions.

•The flash does not fire during movie recording. This is

indicated by on the monitor screen.

Flash

•The flash unit may not be able to charge when battery

power is low. Low battery power is indicated by the on

the monitor screen, and when the flash fails to fire

properly resulting in poor image exposure. When these

symptoms occur, charge the camera’s battery as soon as

possible.

•When the red-eye reduction mode ( ) is selected, flash

intensity is adjusted automatically in accordance with the

exposure. The flash may not fire at all when the subject is

brightly lit.

•Using flash in combination with another light source

(daylight, fluorescent light, etc.) can result in abnormal

image colors.

BASIC IMAGE RECORDING

Recording Macro Images

You can select either normal or macro (close-up) recording

using the selector located on the left side of the camera.

The table below describes the two settings available with

the selector.

•The distances indicated above represent the distance

from the camera’s lens surface to the subject.

Align the Normal ( )/

Macro ( ) selector with

“ ”.

Record the image.

Normal ( )/Macro ( )

selector

To do this:

Shoot normal images, at a distance of

about 1m (39.4˝) to infinity (Normal)

Shoot close-ups, at a distance of about

30cm (11.8˝) (Macro)

Select this setting:

IMPORTANT!

• Selecting the macro mode causes the indicator

to appear on the monitor screen.

• Normally, you should leave the Normal ( )/Macro

() selector setting at “ ”.

BASIC IMAGE RECORDING

Using the Self-timer

The self-timer lets you select either a 2-second or 10-

second delay of the shutter release after you press the

shutter release button. A Triple Self-timer feature lets you

perform three consecutive self-timer operations to record

three images.

In the REC mode, press [MENU].

Use [] and [] to select the “REC”tab.

Use [] and [] to select “Self-timer”, and

then press [].

Use [] and [] to select the self-timer time

you want to use, and then press [SET].

• Selecting “Off” in step 4 disables the self-timer.

• With the Triple Self-timer, the camera records a

series of three images in the sequence described

below.

1. The camera performs a 10-second countdown and

then records the first image.

2. The camera prepares to record the next image.

The amount of time required for preparation

depends on the camera’s current “Size” and

“Quality” settings, the type of memory (built-in or

card) you are using for image storage, and

whether or not the flash is charging.

3. After preparation is complete, the indicator “1sec”

appears on the monitor screen, and another

image is recorded one second later.

4. Steps 2 and 3 are repeated once more to record

the third image.

To do this:

Specify a 10-second self-timer

Specify a 2-second self-timer

Specify Triple Self-timer

Disable the self-timer

Select this setting:

10 sec

2 sec

Off

BASIC IMAGE RECORDING

Record the image.

• When you press the

shutter release button,

the self-timer lamp

flashes and the shutter

releases after the self-

timer reaches the end

of its countdown.

• You can interrupt an

ongoing self-timer

countdown by pressing

the shutter release

button while the self-

timer lamp is flashing.

NOTES

• The “2 sec” self-timer setting is best when shooting

with a slow shutter speed, because it helps to avoid

blurring of images due to hand movement.

• You can use the key customization feature (page 75)

to configure the camera so the self-timer setting

changes whenever you press [] and [] while in the

REC mode.

Specifying Image Size and Quality

You can specify the image size and image quality to suit

the type of image you are recording.

To specify the image size

In the REC mode, press [MENU].

Use [] and [] to select the “REC”tab.

Use [] and [] to select “Size”, and then

press [].

Use [] and [] to select the setting you

want, and then press [SET].
