OTHER RECORDING FUNCTIONS
•Starting a movie record operation causes optical
zoom to be disabled. Only digital zoom is available
while a movie record operation is in progress. If you
want to use optical zoom to record a movie, perform
the zoom operation before starting the record
operation.
•The focus mode automatically changes to Pan Focus
(page 72) when you enter the Movie mode,
regardless of the mode memory’s (page 105) Focus
setting. You can, however, change to another focus
mode before starting a recording.
3.When movie recording is complete, the movie
file is stored in file memory.
1.Press [] (REC), and
then select “
 Movie”
as the recording mode
(page 48).
•This enters the Movie
mode and causes “” to
appear on the monitor
screen.
•You can use the key
customization feature
(page 104) to configure
the camera to enter the
Movie mode whenever
you press [
] or [] while
in a REC mode.
2.Point the camera at the
subject and then press
the shutter button.
•Movie recording
continues as long as
remaining memory
capacity allows, or until
you stop it by pressing

OTHER RECORDING FUNCTIONS
—Auto Focus is not performed in the case of the
Pan Focus (
), Manual Focus () and Infinity
() focus modes, and so no confirmation tone
sounds. In the case of the Manual Focus mode,
you cannot adjust focus settings while recording
is in progress. Be sure to make all adjustments
before beginning the record operation.
•Certain types of memory cards take longer to record
data, which can cause movie frames to be dropped.
 and REC flash on the monitor screen during
recording to let you know when a frame has been
dropped.
 IMPORTANT! 
•The flash does not fire in the Movie mode.
•This camera also records audio. Note the following
points when recording a movie.
—Take care that you do
not block the
microphone with your
fingers.
—Good recording
results are not
possible when the
camera is too far from
the subject.
—Operating camera buttons during recording can
cause button noise to be included in the audio.
—Movie audio is recorded in monaural.
—The camera automatically switches to Pan Focus
(
) (page 72) whenever you enter the Movie
mode.
—The camera focuses automatically whenever you
have Auto Focus or Macro (
) (page 68)
selected as the focus mode. Note that the
confirmation tone that sounds during the Auto
Focus operation will be recorded in the audio. If
you do not want confirmation tones in your audio,
keep Pan Focus (
) as the focus mode, or
select Manual Focus () and manually focus the
image before starting your recording.

files: one for the image data and one for the audio
data. Each file is stored in a different folder in
camera memory (page 172).
1.Press [] (REC), and then select  “
(+)” as the recording mode  (page 48).

OTHER RECORDING FUNCTIONS
Using the Histogram
You can use the [DISP] button to display a histogram on
the monitor screen. The histogram lets you check exposure
conditions as you record images (page 26). You can also
display the histogram of a recorded image in the PLAY
mode.
Histogram
•A histogram is a graph that represents the lightness of an
image in terms of the number of pixels. The vertical axis
indicates the number of pixels, while the horizontal axis
indicates lightness. You can use the histogram to
determine whether an image includes the shadowing (left
side), mid tones (center), and highlighting (right) required
to bring out sufficient image detail. If the histogram
appears too lopsided for some reason, you can use EV
shift (exposure compensation) to move it left or right in
order to achieve better balance. Optimum exposure can
be achieved by correcting exposure so the graph is as
close to the center as possible.

 Audio Recording Precautions
•Keep the microphone on the
front of the camera pointed
at the source.
•Take care that you do not
block the microphone with
your fingers.
•Good recording results are not possible when the camera
is too far from the subject.
•Pressing the power button or pressing [
] (PLAY) stops
recording and stores any audio recorded up to that point.
•You can also perform “after-recording” to add audio to a
snapshot after recording it, and also change the audio
recorded for an image. See page 122 for more
information.

OTHER RECORDING FUNCTIONS
•When the histogram is too far
to the right, it means that
there are too many light
pixels.
This type of histogram results
when the overall image is
light. A histogram that is too
far to the right may result in
“white out” of the light areas of
an image.
•A centered histogram
indicates that there is good
distribution of light pixels and
dark pixels. This type of
histogram results when the
overall image is at optimal
lightness.
•An RGB histogram that shows the distribution of R (red) ,
G (green) , and B (blue) components is also displayed.
This histogram can be used to determine whether there is
too much or too little of each of the color components in
an image.
 NOTE 
•You can use key customization (page 104) to
configure the camera to perform exposure
compensation whenever you press [
] or [] while in
a REC mode. If you do this, you can adjust exposure
compensation while viewing the on-screen histogram
(page 76).
•When the histogram is too far
to the left, it means that there
are too many dark pixels.
This type of histogram results
when the overall image is
dark. A histogram that is too
far to the left may result in
“black out” of the dark areas
of an image.

REC Mode Camera Settings
The following are the settings you can configure before
recording an image using a REC mode.
•ISO sensitivity
•Sharpness
•Saturation
•Contrast
•Grid on/off
•Image Review on/off
•Icon Help on/off
•L/R key setting
•Power on default settings
•Resetting the camera
 NOTE 
•You can also configure the settings listed below. See
the referenced pages for more information.
—Size (page 65)
—Quality (page 66)
—White Balance (page 78)
—Digital Zoom (page 57)
—AF Area (page 70)
—Auto PF (page 69)
—Flash Intensity (page 61)
—Flash Assist (page 61)
 IMPORTANT! 
•Note that the above histograms are shown for
illustrative purposes only. You may not be able to
achieve exactly the same shapes for particular
subjects.
•A centered histogram does not necessarily
guarantee optimum exposure. The recorded image
may be over-exposed or under-exposed, even
though its histogram is centered.
•You may not be able to achieve an optimum
histogram configuration due to the limitations of EV
shift.
•Use of the flash as well as certain shooting
conditions can cause the histogram to indicate
exposure that is different from the actual exposure of
the image when it was recorded.
•The histogram does not appear when you are using
Coupling Shot (page 85) or Pre-shot (page 87).
•The RGB (color component) histogram is displayed
for snapshots only. In the Movie mode, only the
luminance distribution histogram appears on the
monitor screen.

OTHER RECORDING FUNCTIONS
 IMPORTANT! 
•Under certain conditions, a high shutter speed in
combination with a high ISO sensitivity setting can
cause digital noise (graininess), which makes an
image appear rough. For clean, good-quality images,
use the lowest ISO sensitivity setting possible.
•Using a high ISO sensitivity setting along with the
flash to shoot a nearby subject may result in
improper illumination of the subject.
 NOTE 
•You can use the key customization feature (page
104) to configure the camera so the ISO sensitivity
setting changes whenever you press [
] and []
while in a REC mode.
Specifying ISO Sensitivity
You can change the ISO sensitivity setting for better
images in places where lighting is dim or when you are
using faster shutter speeds.
•ISO sensitivity is expressed in terms of values that
originally indicated the sensitivity to light for photographic
film. A larger value indicates higher sensitivity, which is
better for recording when available lighting is dim.
