The flash is activated automatically when there is insufficient light, or when the camera is
shaken. To take pictures with no flash in dark places, set the flash mode to [ $] and set as
follows:
Increase the [ISO] setting

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. 25)
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. 24)
• 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
g “WB Adjusting the color of a picture” (P. 24)
• Take pictures with K in s mode. Suitable for taking pictures on a sunny day at the
beach or in the snow.
g “ s (Scene) Selecting a scene mode according to the shooting situation” (P. 23)
• Often, bright subjects (such as snow) turn out darker than their natural colors. Use 1F to
adjust toward [+] to make these subjects closer to their true shades. Conversely, when you
are shooting dark subjects, it can be effective to adjust toward the [–]. Sometimes, using the
flash may not produce the brightness (exposure) that was intended.
g “ 1F button Changing picture brightness (Exposure Compensation)” (P. 16)
• When [SHADOW ADJ. ON] is selected, 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. 17)
• 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. 25)
• 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.
g “ 3# button Flash shooting” (P. 16)
