ISO sensitivity is a value that expresses sensitivity to light. A 
larger value indicates higher sensitivity, which is better for 
shooting when available lighting is dim. If you want to use faster 
shutter speeds, you should use a higher ISO sensitivity value. 
Under certain conditions, a fast shutter speed in combination 
with a high ISO sensitivity setting can cause digital noise, which 
makes an image appear rough. For clean, good-quality images, 
use the lowest possible ISO sensitivity setting.
1.In a REC mode, press [MENU].
2.On the “Quality” tab, select “ISO” and then 
press [ X].
3.Use [ S] and [ T] to select the setting you want 
and then press [SET].
IMPORTANT!
• Using flash with high ISO sensitivity can cause problems 
with subjects that close to the camera.
• “Auto” ISO sensitivity always is used for movies, regardless 
of the current ISO sensitivity setting.
• You can use the key customization feature to configure the 
[W ] and [ X] buttons so they control the ISO sensitivity 
setting (page 140).
• “Anti Shake” Image Blur (page 123) operates properly only 
when “Auto” is selected for the ISO sensitivity setting.

The metering mode determines what part of the subject is 
metered for exposure.
1.In a REC mode, press [MENU].
2.On the “Quality” tab, select “Metering” and 
then press [X].
3.Use [ S] and [ T] to select the setting you want 
and then press [SET].
 Multi (Multi Metering)
Multi-pattern metering divides the image into 
sections and measures the light in each 
section for a balanced exposure reading. The 
camera automatically determines shooting 
conditions according to the measured lighting pattern, and 
makes exposure settings accordingly. This type of metering 
provides error-free exposure settings for a wide range of 
shooting conditions.  Center Weighted
Center weighted metering concentrates on the 
center of the focus area to measure light. Use 
this metering method when you want to exert 
some control over exposure, without leaving 
settings totally up to the camera.
 Spot
Spot metering takes readings at a very small 
area. Use this metering method when you 
want exposure to be set according to the 
brightness of a particular subject, without 
being affected by surrounding conditions.

IMPORTANT!
•The metering mode will change to “Center Weighted” 
automatically if you change the EV shift value (page 126) to 
anything other than 0.0 while “Multi” is selected. The 
metering mode will change back to “Center Weighted” 
when the EV shift value is changed back to 0.0.
• When “Multi” is selected as the metering mode, the   
icon will not be displayed on the monitor screen when you 
return to a REC mode information display (page 253). You can use the procedure below to expand the dynamic range, 
which makes it possible to capture the bright areas of an image 
while reducing the chance of underexposure. When shooting a 
subject that is back lit, for example, an expanded dynamic range 
minimizes underexposure.

Timestamp, you can do so later using the DPOF function 
and the printing software function (page 214).
• Once date and time information is stamped in a print, it 
cannot be edited or deleted.
• Use the “Date Style” setting (page 199) to specify the Year/
Month/Day format of the date.
• The recording date and time are determined in accordance 
with the camera’s clock settings (pages 11, 199) when the 
snapshot is recorded.
• Digital zoom is not supported while date stamping is turned 
on.
• Date stamping is not supported for the following types of 
images.

The on-screen histogram that provides a graphic representation 
of the current exposure of the image. You can also display the 
histogram in the PLAY mode for information about the exposure 
levels of images.
1.Press [S] (DISP) as many times as necessary 
to display the histogram (page 53).
NOTE• You can use key customization to configure the [ W] and [ X] 
buttons so they control the EV shift setting. Then you can 
perform EV shift while viewing the results on the on-screen 
histogram (page 140).
■ How to Use the 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. If 
the histogram appears too lopsided for some reason, you can 
use EV shift to move it left or right in order to achieve better 
balance. Optimum exposure can be achieved by EV shifting so 
the graph is as close to the center as possible. For snapshots, 
you can even display individual histograms for R (red), G 
(green), and B (blue). These lines can be used to determine 
whether there is too much or too little of each of the color 
components in an image.Using the On-screen Histogram to

Example Histograms
A histogram towards the left side 
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, as shown in 
the nearby image.
A histogram towards the right side 
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, as shown in 
the nearby image.
An overall well-balanced histogram 
results when the overall image is at 
optimal lightness.
IMPORTANT!
•
A centered histogram does not necessarily guarantee 
optimum exposure. If you intentionally want to over expose 
or under expose the image, you may not want a centered 
histogram.
• Due to the limitations of exposure compensation, you may 
not be able to achieve an optimum histogram configuration.
• Use of the flash and certain shooting conditions can cause 
the histogram to indicate exposure that is different from the 
actual exposure of the image when it was shot.
