Exposure Compensation
This camera features an program AE function that automati-
cally changes shutter speed and aperture in accordance
with available light. In addition, you can also manually adjust
the exposure to compensate for backlighting, indirect indoor
lighting, dark backgrounds, and other special conditions.
To manually adjust the exposure
1.
Set the Function Switch to REC.
2.
Use [+] and [–] to perform exposure compensa-
tion.
• Pressing [+] or [–] displays an EV indicator that shows
the current exposure compensation setting.
• Pressing [+] makes the image on the LCD brighter.
Use it to adjust for dim indoor lighting and backlight-
ing.
• Pressing [–] makes the image on the LCD darker. Use
it to adjust for bright sunlight.
• The EV indicator turns red whenever the compensa-
tion value is at its limit.

OTHER RECORDING FUNCTIONS

This section describes more advanced recording operations
that are also provided by this camera.
Using the Zoom Feature
The zoom features let you move in closer on subjects that
are located far from the camera. You can choose either opti-
cal zoom or digital zoom, or even use them in combination to
increase the size of the original image by four or eight times
its original size.
Using Optical Zoom
Optical zoom enlarges the image by changing the focal dis-
tance of the lens.
You can increase the double the size of the image using op-
tical zoom.
IMPORTANT!
• For Optical Zoom recording, first perform the zoom
operation and then move the camera towards the sub-
ject. Otherwise the lens can be damaged by coming
into contact with the subject when it extends from the
camera during the zoom operation.
• Do not carry the camera around or leave it laying
around with the lens extended.
RECORDING
3.
After adjusting the exposure, press the shutter
button to record the image.
NOTES
• Exposure compensation is generally expressed in
terms of an exposure compensation (EV) value. The
exposure compensation value is always set to zero
whenever you turn on the camera.
• Each press of [+] or [–] changes the exposure com-
pensation value by 0.25EV. A change in either direc-
tion is indicated on the monitor screen by arrows
pointing left (negative correction) or right (positive cor-
rection).
• The normal maximum range for exposure compensa-
tion is –2EV to +2EV. Under certain conditions, how-
ever, the camera may impose lower maximum values
when exposure compensation would result in an im-
age that is too dark or too light.
OTHER RECORDING FUNCTIONS
1.
Slide the Function Switch to REC.
2.
Moving ZOOM slider to-
wards T (telephoto) to
zoom in on the subject,
T W
or W (wide-angle) to
zoom out.
ZOOM slider
Telephoto Wide-angle
3.
Compose the image on the monitor screen,
and then press the shutter button about half
way.
RECORDING
• The exposure compensation value automatically re-
verts to zero whenever the shutter button is pressed.
You can manually reset the exposure compensation
value by using [+] and [–] to change the value back to
zero, which is indicated when the EV indicator disap-
pears from the monitor. EV value is fixed during pan-
orama recording.
• Shutter speed and aperture is fixed whenever you
manually adjust the exposure setting.

After confirming that the Auto Focus operation
is complete, press the shutter button all the
way down to record the image.
• Brightness (aperture) is also affected by using optical
zoom.

Using Digital Zoom
Digital zoom produces a VGA size image (640 x 480 pixels)
that can be double or four times the size of the original im-
age.
Using digital zoom and optical zoom in combination can
zoom an image to 8X.
IMPORTANT!
• The focus range for Auto Focus depends on the digital
zoom setting as shown below.
Digital Zoom Focus Range
0.25m to ∞ (0.8 ' to ∞)
OFF
0.6m to ∞ (2.0 ' to ∞)
2X
1.5m to ∞ (5.0 ' to ∞)
4X
• The camera may not be able to focus on an image
within the Auto Focus frame if the subject is closer
than the distances noted above. In such a case, the
Auto Focus frame changes to white when you press
the shutter button half way.
• Note that 4X digital zoom produces a relatively
rougher image than OFF or 2X when used in combina-
tion with Auto Focus.
See "Using the Record Menu" on page 59 for details on mak-
ing digital zoom settings.
