There are several factors that can cause the picture to appear grainy.

Using the digital zoom to take close-up pictures

• With the digital zoom, part of the image is cropped and enlarged. The greater the

magnification, the grainier the picture appears.

g “DIGITAL ZOOM Zooming in on your subject” (P.27)

Increasing the ISO sensitivity

• When you increase the [ISO] setting, “noise”, which appears as spots of unwanted color or

unevenness in the color, can be introduced and give the picture a grainy appearance. This camera
is equipped with a function to allow shooting at high sensitivity while suppressing noise; however,
increasing the ISO sensitivity can result in some noise, depending on the shooting conditions.

g “ISO Changing the ISO sensitivity” (P.26)

• The reason why there are sometimes differences between the actual colors and the colors recorded

in a picture is related to the light source illuminating the subject. [WB] is the function that helps the
camera determine the true colors. Normally, the [AUTO] setting provides the optimal white balance,
but depending on the subject, results may be better if you manually adjust the [WB] setting.

• When the subject is in the shade on a sunny day
• When the subject is illuminated by both natural light and indoor lighting, such as

when near a window

• When there is no white in the center of the frame

beach or in the snow.

• Often, bright subjects (such as snow) turn out darker than their natural colors. Use

subjects, it can be effective to adjust toward the [-]. Sometimes, using the flash may not
produce the brightness (exposure) that was intended.

• Panning along the camera central axis reduces picture misalignment. When you shoot

close subjects, panning along the axis of the tip of the lens gives good results.

• In [COMBINE IN CAMERA 1] mode, the camera automatically detects its own position

except for the following cases (In such cases, use [COMBINE IN CAMERA 2] or
[COMBINE IN PC].) :

• when panning the camera in a quick or unsteadily manner.
• when shooting a low contrast subject (blue sky, etc.).
• when shooting a moving subject framed in full screen.
• when panning the camera with no images on-screen.

• When Shadow Adjustment Technology is set to [ON], the subject’s face appears brighter even

against backlight and the color of the background is enhanced in the picture. This function can
also be used to shoot a subject inside a home or building from outside.

g “f Brightening the subject against backlight” (P.18)

• With [ESP/n] set to [n], the picture can be taken based on the brightness at the center

of the monitor without being affected by the light in the background.

g “ESP/n Changing the area for measuring the brightness of a subject” (P.28)

• Set the flash to [

#] to activate fill-in-flash. You can shoot a subject against backlight

without the face of the subject appearing dark. [

#] is effective for shooting against

backlight and under fluorescent and other artificial lighting.
