• The initial factory default image size setting is 10M (10 million pixels).
• Selecting 3:2 records images with an as pect ratio of 3:2, which matches the 
standard aspect ratio of print paper.
• The letters “HDTV” stand for “High Defini tion Television”. An HDTV screen has an 
aspect ratio of 16:9, which makes them  wider than the usual 4:3 aspect ratio of 
television screens of the past. Your camera can record images that are compatible 
with the aspect ratio an HDTV screen.

ISO sensitivity is a measure of sensitivity to light.
1.In the REC mode, press [ 8].
2.Use [ 8] and [ 2] to select the third control panel option from the top 
(ISO Sensitivity).
3.Use [ 4] and [ 6] to select the setting you  want and then press [SET].
• The current ISO sensitivity setting is  used when shooting a high speed movie 
in the  M (manual exposure) mode. For all ot her types of movies, “AUTO” is 
used as the ISO sensitivity setting.
•“ S  Image AS” (page 95) can be used onl y when the ISO sensitivity setting is 
“AUTO”.
• An ISO setting of ISO 400 or greater is not supported when the “Image Size” 
setting is “RAW+”. If the ISO setting is “ISO 400” or greater when you change 
the “Image Size” setting to “RAW+”, an ISO  setting of “ISO 200” will be used for 
recording.
• Higher ISO sensitivity values tend to  result in digital noise in images.
• Since higher ISO sensitivity values tend  to result in digital noise in images, the 
camera performs a noise filtering proc ess. Because of this, it may take 
relatively longer for the camera to finish  recording an image after it is shot. You 
will not be able to perform any key operation while image recording is in 
progress.

• When “‡ Auto WB” is selected for the white balance setting, the camera 
automatically determines the white point  of the subject. Certain subject colors 
and light source conditions can caus e problems when the camera tries to 
determine the white point, which makes proper white balance adjustment 
impossible. If this happens, select the wh ite balance setting that matches your 
shooting conditions (Day light, Overcast, etc.).
You can manually adjust an image’s exposure  value (EV value) before shooting it.
• Exposure Compensation Range: –2.0 EV to +2.0 EV
• Unit: 1/3EV
1.In the REC mode, press [ 8].
2.Use [ 8] and [ 2] to select the fifth control panel option from the top (EV 
Shift).
3.Use [ 4] and [ 6] to adjust the exposu re compensation value.
To cancel exposure compensation, change 
the EV value to 0.0.
4.Press [SET].
This applies the exposure compensati on value. The exposure compensation 
value you set remains in effect until you change it or turn off the camera (which 
causes it to revert to “0.0”).
NOTE
• When shooting under very dark or very brig ht conditions, you may not be able to 
obtain satisfactory results even after performing exposure compensation.
• EV shift is disabled while the “High Speed Lighting” BEST SHOT scene is being  use.
Correcting Image Brightness (EV Shift)
[6 ] : Increases the EV value. A higher EV 
value is best for light-colored subjects 
and backlit subjects.
[ 4 ] : Decreases the EV value. A lower EV 
value is best for dark-color subjects 
and for shooting outdoors on a clear 
day.

IMPORTANT!
• The camera will not release the shutter unless the flash unit is raised when any one 
of the following conditions exists. Be sure  to raise the flash unit whenever shooting 
with flash is required.
– When shooting with Flash CS, wh ich requires the flash to fire
– When  < (Flash On) is selected for the flash mode
– When  > (Auto Flash) or  ¥ (Red-Eye Reduction) is selected for the flash mode 
and the camera judges that flash is required
NOTE
• Take care to ensure nothing is close to or in  contact with the flash unit when it fires. 
Also make sure that the flash unit and the area around it is not dirty. Objects, dust, 
or dirt near the flash unit can be burned when the flash fires.
• Take care so your fingers and the strap do not block the flash.
• The desired effect may not be obtained when the subject is too far away or too  close.
• Flash charging time depends on operating  conditions (battery condition, ambient 
temperature, etc.). With new batteries it takes about 5 seconds.
• Flash charging time and operation are a ffected by the remaining battery capacity.
The flash will take longer than normal to  charge if it is being used when the battery 
level indicator is showing   or   while  “Alkaline” is selected for the “Battery 
Type” setting (page 19).
 indicates that the flash  is disabled. Replace batte ries as soon as possible.
• Shooting with flash turned off when lighting  is dim results in a slow shutter speed, 
which can cause image blur due to camera movement. Under such conditions, 
secure the camera with a tripod, etc.
• With red eye reduction, the flash is fi red automatically in accordance with 
exposure. It does not fire in  areas where lighting is bright.
• The presence of outdoor sunlight, fluorescent  lighting, or some other light source 
can cause abnormal image colors.
• Select 
? (Flash Off) for the flash setting when shooting in areas where flash 
photography is prohibited.
• While A, S, or M is selected for the ex posure mode, the flash will not fire if > (Auto 
Flash) or  ¥ (Red Eye Reduction) is selected as  the flash mode. If you want the 
flash to fire, select  < (Flash On) as the flash mode. 
						

							
48Snapshot Tutorial
Red-eye Reduction
Using the flash to shoot 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. When  ¥ (Red-Eye Reduction) is selected as the 
flash mode, the camera fires a pre-flash to  cause the irises in the eyes of any people 
in the image to close, which reduces the chance of red eye.
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).
• Red-eye reduction may not work very well  if the subjects are located far away from 
the camera.
Other Useful Flash Features

Your camera provides you with 20X optical zoom (that changes the lens focal 
distance), which can be used in combinati on with digital zoom (that digitally 
processes the center portion of the image to  enlarge it) for total zoom capabilities of 
20X to 318.8X. The image deterioration point depends on the image size (page 51).
1.In the REC mode, slide the zoom controller to zoom.
• Sliding the zoom controller as far as it wi ll go in either direction will zoom at 
high speed.
2.Press the shutter button  to shoot the image.
NOTE
• The higher the digital zoom factor, the coarser the recorded image. Note that the 
camera also has a function that lets y ou record using digital zoom without image 
deterioration (page 50).
• Use of a tripod is recommended to protect against image blur due to camera  movement when shooting with telephoto.
• Performing a zoom operation changes the lens aperture.
• Digital zoom is disabled while “RAW+”  is selected for the “Image Size” setting 
(page 39).
• Both optical zoom and digital zoom  are disabled during high speed movie 
recording.
• Both optical zoom and digi tal zoom are disabled when Á (Super Macro) is 
selected as the focus mode.
Shooting with Zoom
z  (Telephoto) : Enlarges the subject and narrows the range.
w  (Wide Angle) : Reduces the size  of the subject and broadens the range.

If you hold the zoom controller towards z (Telephoto), the zoom operation will stop 
when the optical zoom factor reaches its  maximum. Momentarily releasing the zoom 
controller and then holding it again towards  z (Telephoto) will switch to digital 
zoom, which you can use to se t an even higher zoom factor.
• If you do want to use digital zoom, change the “Digital Zoom” setting to “On” (page  98).
• During zoom, a zoom bar on the monitor screen shows the current zoom setting.
